TWO NEW TAXA IN CYRTOPODIUM (ORCHIDACEAE) FROM SOUTHERN BRAZIL

Abstract

Cyrtopodium kleinii and  C. brandonianum subsp.  lageanum (Cyrtopodiinae, Cymbidieae, Orchidaceae) from southern Brazil are described and illustrated.  Cyrtopodium kleinii is similar to a group of terrestrial species characterized by their small pseudobulbs, buried underground, and small flowers, but it can be distinguished by the color of its flowers, lip lateral lobes slightly or not falcate and subequal in length and width, lip midlobe base with little or no constriction, and geographical distribution. Cyrtopodium brandonianum subsp. lageanum is similar in general flower color to typical C. brandonianum, but it can be distinguished by its earlier flowering, leaves poorly developed at anthesis and different shape and colour of the lip. Both taxa are rare and only known from southern Brazil.
