UDC 582.594.2:581.92(597)
Abstract
Two new species of Cymbidium sect. Jensoa (Orchidaceae) are described from southern Vietnam as new for science under the names C. ledinhhienii and C. sungwookii. Both species morphologically are most similar to C. nanulum but clearly differ by the epigeous pseudobulbs and articulate perennial leaves when plant flowers with leaves. Diagnostic characters of C. ledinhhienii are median lip lobe elliptic to narrowly ovate, 1–1.2 cm long, 6–7 mm wide, disc lamellae divergent in the middle, column apex straight, not lobed, and anther cap smooth, without beak; diagnostic characters of C. sungwookii are triangular ovate median lip lobe, ca. 1 cm long and wide, disc lamellae convergent distally, column apex cleft, with two lobes, and finely papillose beaked anther cap. The paper presents standard illustrated taxonomic descriptions of new species, with data on their ecology, phenology, distribution, conservation status, and comparison with related species.
