    "Cuttings of Avocado No. 42 from the residence of Margarita Munoz 4a Avenida Este and 5a Calle Sur, San Jose. This avocado was called to my attention by Don Anastasio Alfaro, Director of the National Museum. He recommends it as one of the best known to him and a variety of unusually late ripening season. The parent tree, which stands in a small back yard about 10 feet from a house, is 30 feet high, slender in form with a straight trunk 15 inches thick at the base, branched 8 feet above the ground.  At this time (June 1920) the fruits are not half grown, but judging from their present appearance and a plaster of Paris model made last year by Sr. Alfaro, it is possible to say, the form is oval to broad pyriform and that it is up to one pound in weight. The color is said to be green, the seed not unreasonably large, and the flesh of excellent quality. The season of ripening is September to November, sometimes to December.  Most of the avocados in this region ripen in August and September. The tree is a heavy bearer, the fruits sometimes being produced in clusters of two or three." (Popenoe, June 9, 1920.)
