PBS is in the later phase of preparing for publication (online) the monograph "The Genus Hippeastrum in Bolivia" by Lara and Vasquez, including a key updated from the one posted by Dr. Suarezmotta. It covers only species found in that country, however, and not those of Peru, which presumably is the source of the two for which Diana has the names H. machupijchensis and H. cuzcoensis (note that these names are spelled wrong, as they should end in -ense; they may once have been called Amaryllis etc., which is feminine). The same is probably true of the Fontqueria article sent by Dr. Suarezmotta. H. yungascense, mentioned by Diana, is included as a valid species among the Bolivian group. Over the two centuries during which Hippeastrum species have been described, many peculiar things appear to have happened. Some have been described on the basis of a single specimen and never found again, and at least one was only refound quite recently. A couple have been described from cultivation and never found in the wild. A disagreement among botanists led to much of the 20th-century literature being published under Amaryllis rather than Hippeastrum, particularly in the journal Plant Life (Stanford). The beauty of these plants encouraged their cultivation from pre-Columbian times to the present, and bulbs found in nature may have hybridized freely in gardens. One cannot entirely blame botanists for the confusion. According to Lara's book, many hippeastrums grow naturally in densely vegetated areas that are very difficult of access even today. The author has included a chapter on the refinding of one species, with photos of his assistants crossing a swift river on a raft made of saplings and climbing a vertical cliff to photograph plants in flower.
