Epiphytes ; stems elongate or pseudobulbous. Leaves never plaited. 

 Flowers racemose, often large and handsome. Sepals subequal, lateral 

 obliquely adnate to the foot of the column, and forming with it a sac or 

 inentum. Lip contracted at the base, rarely clawed, adnate to and 'incum- 

 bent on the foot of the column, side lobes embracing the column or 

 spreading or 0, terminal narrow or broad, flat, convex, concave or saccate, 

 disk often lamellate. Column short, foot long or short, top angled or 

 2-toothed ; anther 2-celled ; pollinia 4, free, ovoid or oblong, compressed, 

 closely collateral in pairs in each cell. Species about 300, Tropical Asiatic, 

 Australasian and Polynesian. 



The following attempt to arrange the Indian species of this vast and very intri- 

 cate genus into definable groups is open to much criticism in detail. It has entailed 

 many months of labour, and it must stand or fall according to the verdict of those 

 who may use it. 



Series I. Inflorescence terminal (that is, from the base of a terminal 

 arrested internode), or both terminal and lateral. (See also some species 

 of sect. Aporum ; lateral in Formosa. 



Sect. I. SARCOPODIUM. Pseudobulbs short, erect, uninodal, seated singly on a 

 stout creeping rhizome. Leaves 2, terminal, opposite, coriaceous, flat, persistent. 

 Flotvers solitary from between the leaves, or on a ]-few-fld. scape, large or medium- 

 sized ; mentum short, rounded. Habit of Bulb ophy Hum, sect. Sestochilus. 



Sect. II. BOLBODIUM. Pseudobulbs erect, as in Sarcopodium, but more tufted, 

 clavate and stipitate. Leaves *2, terminal, opposite, coriaceous, flat, persistent. 

 Flowers solitary or few from between the leaves, medium-sized, white; mentum 

 large, longer than the lateral sepals, conical, incurved. 



Sect. III. CADETIA. Stem branched, pendulous, branches forming chains of 

 uninodal sessile or stipitate pseudobulbs. Leaf solitary, terminal, coriaceous, flat, 

 persistent. Flowers 1-2 from the base of the leaf, medium-sized, white or pale ; 

 mentum short or elongate. 



Sect. IV. STACHYOBIUM. Stems tufted, forming a small polynodal pseudobulb, 

 or more or less elongate, often compressed, simple or branched. Leaves many, 

 narrow, membranous, deciduous or persistent. Flowers solitary, or in slender ter- 

 minal or terminal and lateral racemes, small or medium-sized, often white; mentum 

 rather long, conical, incurved, or short and obtuse ; lip with often a flat keel on the 

 disk that terminates in a truncate crenate callus on the midlobe. Small species of 

 this section resemble Eria, sect. Bryobium. 



Sect. V. FORMOSA. Stems rather short, tufted, leafy, usually suberect, often 

 with deciduous black hairs on the sheaths. Flotvers solitary or racemose, often large,
