These plants differ from the Costa Riean representatives of P peruvianus in
several particulars but I believe they can be included in the specific concept
without injustice. The stems up to 40 cm long and the less rigid habit may be
the result of different growing conditions at a lower altitude, but the structure
and shape of leaves are alike. If a subsequent examination of the type of P.
valenciae (C. M.) Par. (Caiharinea vaiaiciae C. M.) shows no substantial differences,
I suspect that Brotherus' name will have to be relegated to synonymy in
favor of the earlier published epithet.
A complete set of the species listed above is in the herbarium of The New
York Botanical Garden and a duplicate set in the writer's herbarium.
