Five new Mesoamerican species are described in the orchid genera Chysis, Scaphyglottis, and Sobralia.Chysis addita Dressier (Chiapas) and C. orichalcea Dressier (El Salvador), described here, are allies of Chysis laevis Lindley with shorter and wider segments; C. addita has laminar keels and winglike extensions on the column foot; the predominantly yellow C. orichalcea has convex lat¬ eral lip margins.The new species Scaphyglottis bicallosa Dressier (Costa Rica) has smaller, more nu¬ merous flowers than S. amparoana (Schlechter) Dressier and a higher, bilobed callus.Also new, Scaphyglottis monspirrae Dressier (Panama) has narrower leaves than S. punctulata (Reichenbach f.) C. Schweinfurth and a three-lobed lip.Another novel species, Sobralia purpurea Dressier (Costa Rica), has lanceolate leaves 1-2.5 cm wide and an intensely purple, oblong lip.The synonymy of Chysis bruennowiana Reichenbach f. & Warscewicz and the identity of C. tricostata Schlechter are dis¬ cussed.New combinations are published for Arpophyllum giganteum subsp.alpinum (Lindley) Dressier, A. giganteum subsp.medium (Reichen¬ bach f
