Ballot results on proposed changes to ISTA List of Stabilized Names


A. First ballot

Date: 28 September 2012
Respondents: Baum, Chauvet, Dawson, Diederichsen, Ettekoven, Green, Hammer, Hetterscheid, Jarvis, Pistrick, Porcher, Wiersema.
Items: from 2 August 2012 Mailing (see also sample ballot)

The majority required to accept a voted item should be:

  1. simple (> 1/2) votes = 3
  2. two-thirds (≥ 2/3) votes = 4
  3. three-fourths (≥ 3/4) votes = 5
Note: On the basis of this vote, a ≥ 3/4 majority is thus required for implementation of the items below. All vote totals recorded below that have gained a ≥ 3/4 majority are therefore underscored.

Item 1. Additions from web report 1:

   1a. "Genus spp." names    (yes = 8    no = 4)
   1b. "Genus hybrids" names    (yes = 10    no = 2)
   1c. Hypericum calycinum    (yes = 12    no = )

   Comments: Diederichsen: As the items in list 1a are not species, there is no problem in using any genus name followed by spp. or spec. in any case. I do not see the point in approving this only for the given cases.
Pistrick: We should not unnecessarily expand our list. Nevertheless taxa of higher level can be used as collective names in the rules, where possible. Well-established names of paraphyletic groups, as Lycopersicon species should not be changed, but synonyms added.

Item 2. Family changes (see web report 2):

  1. putting Aceraceae & Hippocastanaceae into Sapindaceae    (yes = 8    no = 3)
    Comment: Hetterschied: The sinking of Aceraceae and Hippocastanaceae in Sapindaceae has been challenged by a molecular study. So caution is required here.
  2. putting Agavaceae, Hyacinthaceae, Laxmanniaceae, and Ruscaceae into Asparagaceae    (yes = 7    no = 4)
  3. putting Alliaceae into Amaryllidaceae    (yes = 7    no = 3)
  4. putting Asclepiadaceae into Apocynaceae    (yes = 9    no = 1)
  5. putting Asphodelaceae (incl. Aloaceae) and Hemerocallidaceae into Xanthorrhoeaceae    (yes = 7    no = 3)
  6. putting Bombacaceae, Sterculiaceae & Tiliaceae into Malvaceae    (yes = 7    no = 4)
  7. putting Cuscutaceae into Convolvulaceae    (yes = 10    no = 1)
  8. putting Dipsacaceae and Valerianaceae into Caprifoliaceae    (yes = 7    no = 4)
  9. putting Eucryphiaceae into Cunoniaceae    (yes = 10    no = 1)
  10. putting Leeaceae into Vitaceae    (yes = 10    no = 1)
  11. putting Myrsinaceae into Primulaceae    (yes = 10    no = 1)
  12. putting Sparganiaceae into Typhaceae    (yes = 10    no = 1)
  13. putting Taxodiaceae into Cupressaceae    (yes = 10    no = 1)
  14. putting Trapaceae into Lythraceae    (yes = 10    no = 1)
  15. putting Fumariaceae back into Papaveraceae    (yes = 10    no = 1)
  16. putting Nyssaceae back into Cornaceae    (yes = 10    no = 1)
  17. removing Altingiaceae from Hamamelidaceae    (yes = 10    no = 1)
  18. removing Calophyllaceae from Clusiaceae    (yes = 10    no = 1)
  19. removing Cleomaceae from Capparaceae    (yes = 10    no = 1)
  20. removing Montiaceae and Talinaceae from Portulacaceae    (yes = 10    no = 1)
  21. removing Nothofagaceae from Fagaceae    (yes = 10    no = 1)
  22. removing Hydroleaceae from Hydrophyllaceae, and transferring rest of Hydrophyllaceae to Boraginaceae    (yes = 9    no = 1)
    Comment: Pistrick: I favor removing Hydroleaceae from Hydrophyllaceae, but oppose transferring rest of Hydrophyllaceae to Boraginaceae.
  23. transferring part of Apiaceae (i.e. Hydrocotyle) to Araliaceae    (yes = 10    no = 1)
  24. realigning Euphorbiaceae into Euphorbiaceae (sensu stricto), Phyllanthaceae, etc.    (yes = 10    no = 1)
  25. realigning Scrophulariaceae into Calceolariaceae, Linderniaceae, Orobanchaceae, Paulowniaceae, Phrymaceae, Plantaginaceae, Scrophulariaceae (sensu stricto), etc.    (yes = 7    no = 4)
  26. apportioning Flacourtiaceae to Achariaceae, Aphloiaceae, Salicaceae, etc.    (yes = 7    no = 4)
  27. putting Chenopodiaceae into Amaranthaceae    (yes = 6    no = 5)
   Comment:
Baum: Although APG is conducting a very good piece of research, the results do not justify to change classifications and names so quickly especially at the family name. As we enter into an era where whole genomes will be sequenced with relative ease a new picture of relationship will no doubt emerge. Furthermore, personally I am of the opinion that the methods of analysis, including nucleotide sequence of alignment, phylogenetic analyses, inferring classifications from them, etc, are far from robust. Therefore, I am opposed to rush into changing classifications and certainly nomenclature at this point in time.

Item 3. Spelling changes (see web report 3).

   (yes = 12    no = )
   Comments: Baum: I am not sure about Louisiana; perhaps louisianae?
Response from Wiersema: The change to the spelling of Proboscidea louisianica (to louisiana) is a return to the original spelling of Miller (1768). Unfortunately, Thellung altered Miller's original spelling when he transferred his species from Martynia to Proboscidea in 1912, and this altered spelling has been widely adopted. IPNI has reverted to the original spelling, and presumably FNA will do likewise when volume 18 of this flora appears, but since most other references continue to use Thellung's incorrect correction, we should reconsider this one separately.

Item 4. Changes to authorship of names (see web report 4).

   (yes = 12    no = )
   Comments:
Pistrick: Because the question of the amount of Robert Brown's authorship of the Cruciferae in W. T. Aitons Hortus Kewensis remains not clear (cp. Taxonomic Literature and the use of R. Br. In Kubitzki, Index Nominum Genericorum, Names in Current Use, Eur. Garden Fl., Atlas Fl. Eur., Vienna Code 14.5 Ex. 4) it seems to be better to use "R. Br. in W. T. Aiton", not to have new discussions in the question "Brown or Aiton?" soon.
Response from Wiersema: The changes to Art. 46 of the Code (on author citations) first appeared in the 1994 Tokyo Code, and in particular the addition of Ex. 29 (of the Vienna Code), which pertains directly to this case, only first appeared in the 2000 St. Louis Code (there as Ex. 20). However, already in the 1994 Tokyo Code all generic entries of Cruciferae from Hortus Kewensis, ed. 2 in Appendix III were corrected from "R. Br." to "W. T. Aiton", and this correction has been subsequently maintained in the next two codes. It was obviously not taken account of in the 1993 NCU or the 1979 published volumes of ING, although now reflected in the on-line ING and IPNI databases. This change has also been adopted in the 2010 FNA treatment of the family. The discrepancy in Ex. 4 (an Example which traces at least to the 1956 Paris Code) under Art. 14, has unfortunately been overlooked until now, but is to be corrected in the 2012 Melbourne Code. The issue, which affects the names Barbarea vulgaris, Lepidium campestre, Malcolmia maritima, Matthiola incana, and Nasturtium officinale will be put to a second vote.

Item 5. Changes to synonym linkage (see web report 5).

   (yes = 11    no = )
   Comments: none.

Item 6. Taxonomic or nomenclatural changes (see web report 6).

   Item 6a. Nomenclatural changes (indicated by "N"):
  1. Castanopsis hystrix = Castanopsis purpurella
    Comments: Pistrick: GRIN comment not clear: What about a valid publication of Castanopsis hystrix Miq.?
    Response from Wiersema: Castanopsis hystrix Miq. (1863) was validly published, but the problem is the existence of another earlier name, Castanea purpurella Miq. (1861), that apparently applies to this species and has been now transferred to Castanopsis. However, because the new name has yet to be adopted in most Asian references I think we should defer this change. So the case should be voted again.
  2. Centrosema pubescens auct. = Centrosema molle
  3. Dichondra repens auct. = Dichondra micrantha
  4. Eragrostis amabilis = Eragrostis tenella
  5. Ipomoea marginata and Ipomoea sepiaria = Ipomoea sagittifolia
  6. Ipomoea plebeia = Ipomoea biflora
  7. Matricaria recutita and Chamomilla recutita = Matricaria chamomilla
  8. Musa uranoscopos auct. = Musa coccinea
  9. Petunia ×hybrida = Petunia ×atkinsiana
  10. Rheum ×hybridum = Rheum ×rhabarbarum
    Pistrick: Rheum ×hybridum Murray should not be included as a synonym of Rh. ×rhabarbarum L., because it is regarded as an obviously natural hybrid Rh. ×rhaponticum L. × Rh. palmatum L. ((Rudolf Mansfelds Kulturpflanzenverzeichnis, 2. Aufl. 1986, Bd. 1, p. 107, cp. Rothmaler Exkursionsflora von Deutschland, Bd. 5, p. 207)).
    Response from Wiersema: Although Rheum ×hybridum has been accepted in the sense of "garden rhubarb" in some references, and also formerly in GRIN, in view of Klaus's comments it seems best to leave it out. We will vote this one again.
  11. Sedum reflexum = Sedum rupestre
  12. Tripleurospermum perforatum, Matricaria inodora, and Matricaria perforata = Tripleurospermum inodorum
   (yes = 8    no = 1)
   Comments: none.

   Item 6b(1). Taxonomic changes (indicated by "T") to binomials involving generic realignments:

  2. segregation of Senegalia and Vachellia from Acacia    (yes = 7    no = 4)
  3. sinking of Acroptilon into Rhaponticum    (yes = 10    no = )

  9. segregation of Vasconcellea from Carica    (yes = 8    no = 2)
  10. restructuring of Centaurea to include Cnicus and segregate Plectocephalus and Psephellus    (yes = 9    no = 1)
  11. sinking of Xanthocyparis (Chamaecyparis nootkatensis) into Cupressus    (yes = 6    no = 4)
  12. segregation of Dysphania from Chenopodium    (yes = 9    no = 1)
  13. segregation of Tarenaya from Cleome    (yes = 7    no = 3)

  26. segregation of Cyclachaena from Iva    (yes = 7    no = 3)
  27. sinking of Kochia into Bassia    (yes = 10    no = )

  38. segregation of Weingartia from Rebutia    (yes = 8    no = 2)
  39. segregation of Triadica from Sapium    (yes = 10    no = )
  40. segregation of Lomelosia from Scabiosa    (yes = 8    no = 2)

  50. segregation of Pascalia and Sphagneticola from Wedelia    (yes = 8    no = 2)
   Comment: Names not adopted will be added to the Stabilized List as synonyms if not already present.

   Item 6b(2). Taxonomic changes (indicated by "T") to binomials involving species realignments:
  1. including Agropyron sibiricum in A. fragile    (yes = 8    no = 2)
  2. sinking of Annona diversifolia into A. macroprophyllata    (yes = 8    no = 1)
  3. acceptance of Callistemon lanceolatus as distinct from C. citrinus    (yes = 9    no = )
  4. sinking of Campanula colorata into C. pallida    (yes = 10    no = )
  5. sinking of Cenchrus incertus into C. spinifex    (yes = 7    no = 3)
  6. including Commiphora erythraea in C. kataf    (yes = 10    no = )
  7. sinking of Flaveria australasica into F. trinervia    (yes = 8    no = 1)
  8. sinking of Indigofera pseudotinctoria into I. bungeana    (yes = 10    no = )
  9. acceptance of Juncus decipiens as distinct from J. effusus    (yes = 7    no = 3)
  10. acceptance of Lantana strigocamara as distinct from L. camara    (yes = 7    no = 3)
  11. sinking of Leontopodium alpinum into L. nivale    (yes = 9    no = 1)
  12. acceptance of Lolium ×hybridum in place of L. ×boucheanum    (yes = 10    no = )
  13. acceptance of Murraya exotica as distinct from M. koenigii    (yes = 11    no = ) Comment: Wiersema: this should have indicated M. paniculata rather than M. koenigii, which was the subject of a separate favored proposal to be transferred to Bergera. The widely cultivated "orange-jasmine" is currently treated in the Stabilized List as M. paniculata, under which M. exotica has often been synonymized in the literature, but recent research has shown that the two are distinct taxa. Because M. paniculata is not in cultivation, the proposal should have been to change this entry to M. paniculata auct., non (L.) Jack and make it a synonym of M. exotica. A separate ballot will address this issue.
  14. acceptance of Osteospermum ecklonis as Dimorphotheca ecklonis    (yes = 7    no = 3)
  15. sinking of Paspalum wettsteinii into P. virgatum    (yes = 10    no = )
  16. sinking of Rosa wichuraiana into R. luciae    (yes = 10    no = )
    Comments: Pistrick: R. wichuraiana has to be corrected into "R. wichurana" (of Max Ernst Wichura; ICBN 60.11).
    Response from Wiersema: While it is very likely that Crépin was honoring Wichura with his epithet, he did not indicate this directly. Because it is favored to now treat this name, formerly accepted in the Stabilized List and most other places with the spelling "wichuraiana", as a synonym, a new vote can decide the spelling that should be used.
  17. sinking of Solanum diflorum into S. pseudocapsicum    (yes = 10    no = )
  18. sinking of Spermacoce assurgens into S. remota    (yes = 8    no = 1)
  19. acceptance of Glandularia ×hybrida in place of Verbena Hybrida Group    (yes = 8    no = 2)
    Comments: Pistrick: I would prefer "Verbena ×hybrida Groenl. et Rümpler".
    Hammer: I would prefer "Verbena ×hybrida
    Response from Wiersema: In the last edition of the Stabilized List (2007) the decision was made to adopt the segregation of Glandularia from Verbena, resulting in the acceptance of G. canadensis and G. laciniata in place of the corresponding Verbena names. The name V. ×hybrida has not been accepted in the last two editions of the Stabilized List, having been relegated to the synonymy of Verbena Hybrida Group. However, the common "garden verbena" to which these names have been applied, both in the Stabilized List and elsewhere, is the result of hybridization of species now placed in Glandularia. Four options: 1) retaining Verbena Hybrida Group, as before, 2) accepting V. ×hybrida, 3) accepting Glandularia Hybrida Group, or 4) accepting Glandularia ×hybrida will be reconsidered.
   Comment: Names not adopted will be added to the Stabilized List as synonyms if not already present.

   Item 6b(3). Taxonomic clarifications (indicated by "T") involving synonym (and accepted name) additions of binomials:
  1. adding Asparagus densiflorus auct. and A. aethiopicus to clarify misapplication of former name    (yes = 11    no = )
  2. adding Asparagus setaceus auct. to clarify misapplication of this name    (yes = 11    no = )
  3. adding Mentha arvensis auct. Amer. and M. canadensis to clarify misapplication of former name    (yes = 10    no = 1)
    Comment: Pistrick: better var. canadensis (L.)Kuntze ?, cp. Gleason and Cronquist, Manual of Vascular Plants NE US; if necessary M. canadensis could be mentioned in the ISTA list as "included in".
    Response from Wiersema: According to an article in Taxon (51: 703–718. 2002), M. canadensis (2n=96), found in North America and Asia but not in Europe, is an ancient stabilized amphidiploid arising from hybridization of M. arvensis (2n=72) and M. longifolia (2n=24), two Eurasian species not native to North America. Until quite recently the name M. arvensis, occasionally as M. arvensis var. canadensis, has most commonly been used for the North America plants that represent M. canadensis, but usage of M. canadensis is becoming more common so the name should be accounted for. In response to Klaus's comment a few alternatives will be proposed in a separate ballot.
   Comments: none.

   Item 6c. Taxonomic considerations (indicated by "T") involving trinomials:
  1. Acer ginnala    (accept = 4    include in binomial = 2    make synonym of trinomial = 2)
  2. Aconitum vulparia    (accept = 4    include in binomial = 2    make synonym of trinomial = 2)
  3. Arabis caucasica    (accept = 4    include in binomial = 2    make synonym of trinomial = 2)
  4. Bouteloua rothrockii    (accept = 3    include in binomial = 3    make synonym of trinomial = 2)
  5. Bromus marginatus    (accept = 4    include in binomial = 3    make synonym of trinomial = 2)
    Comment: Pistrick: include the trinomial as a synonym
  6. Crambe abyssinica    (accept = 6    include in binomial = 2    make synonym of trinomial = 2)

  9. Helipterum roseum    (accept = 3    include in binomial = 3    make synonym of trinomial = 2)
    Comment: Wiersema: The approval of Rhodanthe as a segregate from Helipterum leaves this without a species name in Rhodanthe, where it has been treated only at subspecies rank under R. chlorocephala. The alternatives will be explored in a separate ballot.
  10. Hordeum spontaneum    (accept = 6    include in binomial = 2    make synonym of trinomial = 2)
  11. Iris florentina    (accept = 3    include in binomial = 3    make synonym of trinomial = 2)

    Comment: Pistrick: include the trinomial as a synonym
  18. Sorghum sudanense    (accept = 4    include in binomial = 2    make synonym of trinomial = 2)
    Comment: Pistrick: without synonym, not too broad S. bicolor, cp. Mansfeld's encyclopedia.
  19. Sporobolus diandrus    (accept = 4    include in binomial = 2    make synonym of trinomial = 2)
    Comment: Pistrick: include the trinomial as a synonym
  20. Trapa bispinosa    (accept = 4    include in binomial = 2    make synonym of trinomial = 2)
  21. Triticum dicoccon    (accept = 5    include in binomial = 3    make synonym of trinomial = 2)
    Comment: Hammer: as Triticum dicoccum Schrank ('dicoccon') to adapt to the still predominant use?
    Response from Wiersema: An item to be explored in a separate ballot.
  22. Triticum durum    (accept = 6    include in binomial = 2    make synonym of trinomial = 2)
  23. Triticum spelta    (accept = 6    include in binomial = 2    make synonym of trinomial = 2)
   Comments:
Diederichsen: I also suggest accepting Medicago falcata as a species name.
Response from Wiersema: We will explore this option in a separate ballot.
Jarvis: I don't have a feel for quite how complicating it might be to introduce trinomials for the first time into the ISTA List. All other things being equal, I would favour aligning the ISTA List with the names accepted in GRIN, including the trinomials. However, given the way in which the Secretary has drawn attention to what is evidently felt to be a significant step, I am cautious about voting in this way without a clearer idea of the implications. I would, however, not be in favour of the "include in binomial" option and if it is decided not to include trinomials, I would favour retaining the currently accepted names.
Pistrick: The ISTA list has been restricted to the species rank traditionally, to remain handleable. This tradition should be continued for practical reasons to avoid an overexpansion. The rank of a species is often much more in the focus of practical users than infraspecific categories, which should be nevertheless mentioned as synonyms, like in our 5th edition.
Green: Prefer to avoid option 3 (make synonym of trinomials) in Stabilized List. Continued use of Option 1 by ISTA may result in non ISTA organizations using one of the other GRIN options, being 'more up to date'. Preference to include in binomial, but in crop species where seed legislation applies (seed certification) there may be implications relating to species purity and varietal purity.
Hammer: Infraspecific rank is not included. But there are many cases where the infraspecific item has much importance. Should those races be included as a synonym on the species level, at least? Or does this proposal inflate the ISTA list too much?
