A NEW AND VEGETATIVELY UNIQUE, SMALL-FLOWERED CYRTOCHILUM (ORCHIDACEAE, ONCIDIINAE), FROM PERU

摘要

A distinctive small-flowered Cyrtochilum (Orchidaceae; Oncidiinae) from Peru is described, illustrated, and compared with similar species. The first record of this species that I am aware of were some flowers submitted by Sheila An-stall of Salt LakeCity, Utah, to the Orchid Identification Center (OIC) in November of 1976. They were subsequently identified as Oncidium cimiciferum (Rchb.f.) Beer (OIC 1150 = Cyrtochilum cimiciferum (Rchb.f.) Dalstrom). During my first visit to Selby Gardens in 1981, Iencountered this specimen, drew a flower and was struck by the odd morphology, not corresponding to that of C. cimiciferum at all. I was unable to find another name for it, however, and put it away in my miscellaneous Oncidiinae file as an unidentifiedspecies.
