Genus SCAPHYGLOTTIS POepp. & Endl.
PlaceOfPublication Nov. Gen. & Sp. 1:58. 1835.
Synonym Cladobium Lindl. Nat. Syst. Bot. 446. 1836 (or 1835?). Hexadesmia Brongn. in Ann. Sci. Nat. Bot. II, 17:44. 1842.
Description Caespitose or repent epiphytic herbs. Stems indurated or pseudobulbose, simply branched, or fasciculately branched (superimposed) above. Leaves 1-3 from the apex of the segments of the stem or pseudobulbs, thin and grass-like to coriaceous or fleshy and terete. Inflorescence a fascicle or a raceme, terminal on the growths or segments of the stem. Sepals subequal, erect. Petals similar to the sepals but usually smaller. Lip articulated from the tip of the column-foot or subarticulated, straight, geniculate, reflexed or recurved, clawed or clawless, entire or 3-lobed, often emarginate. Column short, wingless or winged or auricu- late, produced into a more or less distinct foot at the base; anther terminal, operculate, incumbent, the loculae provided with longitudinal septae; pollinia 4 or 6, if 6 then all of equal size or two smaller than the others, ceraceous, laterally compressed (at least 4 of each set compressed).
Note A difficult but interesting genus of some 40 or 50 species. The generic name Scaphyglottis should, in all probability, be substituted by Cladobium Lindl. The original generic-description of Scaphyglottis obviously applies more to Scaphyglottis parviflora Poepp. & Endl. than to any of the other component species. Of the species described in the original publication most are Maxillaria, and the generic description applies best to those species which belong to the genus Maxillaria.
