25. Cleisostoma.] 159. ORCHIDACE.E. 



large callus protruding so as to meet a smaller callus projecting from the posterior 

 wall, lateral lobes of lip small, apical oblong convex with thin erose edges. Column 

 with a large cheek-like protuberance each side of the rostellum. Anther depressed 

 with a long beak. Capsule -25- -3" (ripe ?). 



26. SACCOLABIUM, Blmne. 



Epiphytes without pseudobulbs, with leafy stems and flat, keeled 

 or terete leaves. Flowers usually small in lateral spikes, racemes or 

 panicles, sometimes subcorymbose. Sepals and petals spreading 

 subsimilar free but adnate to the base of the column, lip sessile at the 

 base of the column, usually consisting of a large saccate or cylindric 

 spur, small lateral lobes and a small midlobe, sac or spur not septate 

 within (as in Sarcanthus) and without a large scale or callus within 

 under the column. Column short, broad, truncate, rarely beaked, 

 Avithout a foot ; anther 1- or imperfectly 2-celled, pollinia 2, entire 

 or 2-partite. 



Our 2 species both belong to section Acampe with keeled thickly coriaceous 

 leaves, flowers corymbose, lip a large hemispheric sac with truncate or short side- 

 lobes and a short warted reniform or ovate adnate erose or fimbriate midlobe, very 

 short column and globose pollinia with linear caudicles. Acampe is now generally 

 maintained as a distinct genus. 

 Midlobe of lip suborbicular or broadly ovate, spur a rounded 



sac tubercled and pubescent at the base within . . .1. prcemorsum. 



Midlobe of lip ovate, spur conical, pubescent within . . 2. papillosnm. 



1. S. praemorsum, Hool: f: Syn. AcamjDe Wightianii, Lindl. 



A small epiphyte with leafy stem 5-6" or up to 1 ft. Leaves 5-7", 

 narrow. Flowers yelloAv with transverse red markings, -5 — 7" diam., 

 papillose all over, on a short stout scape only 1-2" long. Lip deeply 

 lobed, very complicate, midlobe broadly ovate or suborbicular, spur 

 a rounded sac tubercled and pubescent at the base within. 



Hundrughagh, Eanchi, Prain ! Fl. r.s. 



Internodes ■ 5-1" long. Racemes with thick rhachis breaking laterally through 

 the leaf-sheaths. Leaves linear, very firm, premorse, articulate just above their 

 sheath, about 6" long and 1" broad. Bracts minute triangular, but their base 

 shows an aninUar ring. Lip dotted pink. Capsule 2" narrowly fusiform. 



2. S. papillosum, Lindl. Syn. Acampe papillosa, Lindl. 



Stem elongate 2-3 ft. branched, creeping along the tree branches, 

 slender with obliquely notched leaves 3-4" long. Flowers •5--7" 

 diam., capitate on a short scape only 1-2" long w'hich is closely scarred 

 (nodal scars) to the base. Lip with ovate midlobe and short conical 

 spur pubescent within. 



Sarguja, Cardon ! Fl. July (Oct.-Jan., Puntliny). 



Stems (according to Paiitling) erect rigid clustered -35" thick bearing many sub- 

 horizontal coriaceous curved deeply channelled (as in last) leaves 3-4" by -6- -8", 

 apiculate at the unequal tip. Peduncle only about -5" bearing a sub-corymbose 

 4-8-fld. raceme. Flowers somt>times -7" across {F.B.I.), sepals and petals yellow 

 with brown bars {Liinllci/ shows red dots), oblong, petals narrower sub-spatliulate, 

 lip slightly longer, decurved, ovate-oblong, white with pale purple markings crenate 

 and transversely rugulose and with a cylindric slightly tapering pale-yellow spur, 

 hairy within, side-lobes 0. Capsule fusiform, ridged, 1-25" long.
