Agrostopliyllum.] CXLYIII. OROHIDE^E. (J. D. Hooker.) 825 



PEBAK, Scortechini. 



Stems 18-20 in., naked below, flexuous. Leaves % in. diam., thin. Peduncles 

 -j\ T in. ; flowers Jg- in. 



Species of doubtful position. 



6. A. ZEYLANICUM, HooJc.f. ; leaves 4-5 by i in. flaccid, base slightly 

 contracted, tip rounded, sheath 1-2 by ' in. truncate, ovary obtuse-angled 

 very much longer than the obtuse bracts. Ceylon, McKenzie, Walker, 

 " Abundant on the road to Adam's Peak on trees." I have seen only two 

 specimens ; in one the flowers are too withered for analysis, the other is 

 monstrous with the head filled with fascicles of setaceous bracts. The thin 

 flaccid leaves are peculiar. 



31. CERATOSTYLIS, Wume. 



Epiphytic low herbs with fibrous roots ; stems tufted, simple or branched, 

 sheathed, sometimes leafless and rush-like. Leaves narrow, coriaceous, 

 fleshy or subterete, rarely thin. Flowers minute, solitary, or few in a small 

 cluster of bracts. Sepals erect, conniving ; lateral broader, forming with 

 the foot of the column a gibbous or short spur-like mentum. Petals nar- 

 rower. Lip adnate to the foot of the column by a long incumbent claw ; 

 blade short, erecto-patent, fleshy, entire. Column short, top broad, 2-lobed, 

 or with two spathulate erect arms ; foot long ; anther 2-celled ; pollinia 8, 

 small, attached in fours or all together by a small viscus. Species 15, 

 Indian, Malayan and Pacific. 



* Stems erect, rush-like. Flowers capitate; mentum spur-like. Arms 

 of column long, erect. 



1. C. teres ? Reiclib.f. in Bonpland. ii. 89, and in Wal-p. Ann. vi. 470 ; 

 flowers pubescent, lip narrowly spathulate, tip thickened concave. Ap- 

 pendicula tere-s, Griff. Notul. iii. 359 ; Ic. PL Asiat. t. 332. 



UPPER ASSAM : near Negregam, Griffith. KHASIA HILLS ; at Amwee, 

 alt. 4-5000 ft., J. D. If. $ T. T. 



Stems 8-12 in., #s thick as a crow-quill, from a stout fibrous rhizome, straight or 

 curved, jointed (or with a terete leaf) at the head of flowers, clothed at the base with 

 appressed scarious sheaths. Heads of flowers ^ J in. diam., sessile lateral or ter- 

 minal, in a tuft of sheathing bracts ; flowers ^ in. long, very shortly exserted ; 

 bracteole cymbiform, acuminate; ovary short, ovate, acuminate; lateral sepals 

 pubescent; petals lanceolate, acute ; mentum as long as the ovary, clavate ; column 

 much shorter than its spathulate arms. 



2. C. malaccensis, Hook. f. Ic. Plant, ined. flowers glabrous, lip 

 lanceolate, tip thickened acute, disk with 3 ridges. 



PEKAK, Scortechini ; on Batang Padung, alt. 4900 ft., Wray ; Mount Ophir, 

 Griffith (Ke-to Distrib. 5213). 



Habit of C. terex, but stems shorter, flowers quite glabrous, and lip with mem- 

 branous margins. This will probably prove to be a Malay Archipelago species, but 

 1 cannot identify it with any. 



** Stem ascending or pendulous, sheathed throughout, 



ft/ft* of bract ft ; mentum very aJiorL roiut<h-d ; col taint with a broad reniforffl 

 top. 



3. C. clathrata, Ilvok.f.; glaljrous, stems densely tufted, sheatlis 

 clathrately reticulate, leaves terete channelled, flowers pnpillose shortly
