Orchidaceae | Restrepiella | | | | 
|
Orchidaceae | Restrepiella ophiocephala | | Epiphytic on Fraxinus cubensis. | Sw. FL (?); Mexico and Central America. Apparently not considered to have been adequately documented as occurring in FL by FNA26 or WH3. The historical presence of this taxon in s. FL remains dubious as it stems from a single plant apparently collected in Collier County in 1963 by Edgar R. Thomasson, Jr., but then perhaps cultivated for a decade and not vouchered by Luer until 1973 (Luer 069). Whether it had always been a cultivated specimen or had truly originated from Collier County is a detail that will likely be difficult to ascertain. Additionally, its far disjunction from Mexico, while not impossible, follows an uncommon global distribution pattern than that of other epiphytic orchid taxa in s. FL otherwise primarily distributed in the West Indies. |
