T2  - Harvard papers in botany
N2  - A systematic revision of the genus Dichaeu (Orchidaceae) in Costa Rica is presented. The taxonomic history of the genus and its phylogenetic position are discussed, with emphasis on infragenenc grouping. Characters of vegetative and floral morphology are treated, and their taxonoiilic significance is discussed. Twenty-nine Dichnea taxa are recognized for the flora of Costa Rica, and a key to species is provided. Each taxon is described on the basis of Costa Rican material, illustrated in a composite plate, and its distribution in the country is assessed. Distribution maps for all the taxa are given. Overall distribution, derivation of name, notes on species ecology, and diagnostic features are presented for each taxon. Lectotypes are selectcd for D. acostae Schltr., D. acroblephara Schltr., D. amparoana Schltr., D. costaricensis Schltr., D. dammeriana Kraenzl., D. lycopodioides Rchb. f. ex Kraenzl., D. poicillantha Schltr., D. selaginella Schltr., D. tuercklheimii Schltr., Epidendrum echinocarpon Sw., and E. trichocarpon Sw. A new species, D. gomez-lauritoi, is described and illustrated from the wet Caribbean plains of central Costa Rica.
