Pupulin, F. 2004. A note on Prosthechea (Orchidaceae: Laeliinae), with a new species. Selbyana 25(1): 17–22.
Abstract. Current views about the phylogeny of Laeliinae (Orchidaceae) and the systematic position of Prosthechea and related genera are discussed. Morphologic characters used to circumscribe genera in the Prosthechea clade are reviewed. A new species from Costa Rica, P. barbozaei, is described and illustrated. Prosthechea barbozaei is closely related to P. glauca and P. ortizii, from which it may be distinguished by the ligulate sepals and oblong petals, the elliptic-oblong lateral lobes and the suborbicular, retuse rnidlobe of the lip, the shape of the callus and the androclinium, and the vegetative habit, with suborbicular, strongly ancipituous pseudobulbs, respectively.
Key words: Orchidaceae, Laeliinae, Prosthechea, Prosthechea barbozaei, Pseudoencyclia, Anacheilium, Hormidium, Panarica, Pollardia, morphology, systematics, Costa Rica
