Taxon: Pyrus elaeagrifolia Pall.

Genus: Pyrus section: Pyrus
Family: Rosaceae subfamily: Amygdaloideae tribe: Maleae subtribe: Malinae.
Nomen number: 30491
Place of publication: Nova Acta Acad. Sci. Imp. Petrop. Hist. Acad. 7:355, t. 10. 1793
Comments:
  • valid publication verified from original literature
  • according to W. Greuter (pers. comm. via e-mail on 29 Apr 2011), this name was likely intentionally based on the Greek "elaeagros" meaning wild olive tree, not "elaeagnos", and thus the original spelling is not a correctible orthographic error
Name verified on: 05-Jul-2011 by ARS Systematic Botanists. Last updated: 10-May-2012
Species priority site is: Natl. Germplasm Repository - Corvallis (COR).
Accessions: 31 in National Plant Germplasm System.
