Abstract

Notes on Cleistes tenuis are presented, including a detailed description, distribution, and herbarium records. This species is particularly interesting because flowers at full anthesis and preserved in alcohol differ so dramatically from those drawn based on herbarium material and descriptions in the literature, that “two species” easily could be distinguished. Differential drying and shrinking in the labellum, however, account for differences in flowers and in this case are referable to the same species.
