Discussion
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.
