concave, side lobes erect, midlobe recurved ; disk with nsually 2 pubes- 

 cent median ridges. Column long, foot ; anther 1- or imperfectly 

 2-celled ; poUinia 2 deeply grooved or 4, subglobose or pyramidal, sessile on 

 the broad strap or gland. — Species about 30, tropical and subtropical, on 

 the Mountains of Asia, with a few African and Australian. 



* Leaves rudimentary or at flowering time. 



1. C> macrorhlzon, Lindl. Gen.Sf Sp. Orchid. 162; terrestrial, root- 

 stock creeping branched, bracts narrow membranous. 



N.W. India, Royle, Falconer. Khasia Hiils, alt. 5-6000 ft., Lohh, &c. ; 

 Naoa Hills (Herb. Calcutt.). 



Rootstock as thick as a goose-quMl, branched. Scape very short, with the raceme 

 6-9 in., ascending, 6-8.fld. ; basal sheaths short, or elongating to 2 in. and narrowly 

 subfoliaeeous ; bracts J-J in., narrow, membranous ; pedicel with ovary 1 in. ; flower 

 1^— If in. broad, sepals linear-lanceolate, acuminate, and rather broader petals 

 white or pale yellowish with pink striae ; lip white spotted with crimson, side lobes 

 narrow, midlobe ovate obtuse, disk with 2 thick ridges between the side lobes; 

 anther papillose ; pollinia 4, subhemispheric. — A remarkable species, a parasite 

 according to Clarke. Lindley describes the rootstock as jointed, and the ridges of 

 the lip as arcuate. 



2. C. slkkimense, Hook. f. ; epiphytic, bracts minute triangular- 

 ovate. 



SiKKiM Himalaya; Lachen Valley, alt. 6000 ft., J. D. H. 



Rootstoclc very stoat. Scape with many obtuse basal sheaths 2-3 in. long, those 

 higher up 1 in. long ; raceme 4-8 in., more or less deourved, rather stout, 20-30-fld. ; 

 bracts i in. ; pedicel with ovary i-| in. ; dorsal sepal linear-oblong, obtuse ; 

 lateral lanceolate, acute, snbfalcate ; petals elUptic, acute ; lip as broad as long, 

 rhombic-ovate, side lobes obscure rounded, narrowed into the very short ovate mid- 

 lobe, disk without ridges but with 2 obscure rounded calli. — A very distinct 

 species, overlooked by Lindley when studying my Sikkim Orchids, and mixed up with 

 C. aloifolium. 



** Leaves elliptic-lanceolate. 



3. C. lancifolium, Soolc Exot. Fl. t. 51 ; leaves long-petioled

 median lameUae between the side lobes. Lindl. Gen. Sf Sp. Orchid. 164 ; in

Stem 2-6 in., fleshy, fusiform ; sheaths ovate-lanceolate, acuminate ; roots very 

 long, thick and spongy. Leaves 6-10 in., petiole slender, sometimes as long. Scape 

 nodding, 6-8-fld. ; flowers li-2 in. diam. ; .sepals white, yellowish or greenish, 

 lanceolate, acuminate ; petals rather broader, white with a pink midrib ; lip white 

 spotted with red-purple, side lobes narrow, midlobe ovate obtuse.

 very coriaceous, scape with raceme longer than the_ leaves few-fld., bracts 

 lanceolate shorter than the ovary, flower long-pedicelled, lip with 2 glabrous 

 ridges on the disk between the side lobes.
