content: Apparently described from cultivated plants, a "series of living specimens" collected by Maxon in Guatemala in 1905 and sent to the Smithsonian; these plants were assigned different greenhouse numbers and the type made from one of them. The holotype (explicitly cited by USNH number, 535059; greenhouse no. 05.306, specimen apparently made in 1907) is probably the only genuine type; a bulky specimen in the main herbarium bears the same greenhouse number and may be the same plant from which the holotype was made, but probably preserved at a later date.
