Cleisostoma.'] CXLVIII. ORCHIDK^E. (J. D. Hooker.) 75 



ASSAM, Mann. SIKKIM ? (Ic. in Herb. Calcutt.) 



I have seen but one specimen ; it is as small as C. undulatum, from which it 

 differs in the much longer stouter peduncle and raceme, and very small flowers about 

 T ^ in. diam. (pale golden yellow flushed with red at the base of the sepals and 

 petals, according to the Sikkim drawing). Dorsal scale of spur erect, 2-fid ; column 

 very short, anther broad, obtuse, poll'mia subglobose, strap dilated upwards, rather 

 long, gland small. 



14. C. decipiens, Lindl. in Hot. Reg. 1884, Misc. 11 ; leaves 8-10 by 

 1 in. thick purple dotted beneath, peduncle simple or branched, spike 

 many-fid., sepals and petals ovate or oblong-ovate, lip broader than long 

 entire, spur short broad gibbous. C. maculosum, Thwaites Enum. 304 (C. 

 P. 3885) (not of Lindl.} C. Thwaitesianum, Trimeri in Journ. Bot. 1885, 

 244.

A drawing of this plant from the Perideniya Herbarium represents the stem \\ 

 in. long, the leaves 5-6 by f-1 in., lorate, unequally obtusely 2-lobed, sheaths \ in. 

 long, and underside of leaf speckled with purple. Flowering peduncle stout, 

 speckled with purple, with the dense-fld. spike 2 in., lengthening to 6 in. in fruit ; 

 bracts minute, subulate ; flowers i in. diam., yellowish, more or less suffused with 

 red. Capsule sessile, f- in., linear-oblong.- The specimen in Lindley's herbarium 

 (from Hort. Lcddiges) consists of an imperfect leaf 4 by f in. and a few inches of a 

 branched panicle, the flowers not in. diam., are crowded in elongate spikes with a 

 stout rachis. The sepals as drawn by Lindley are obovate-oblong, obtuse, reddish- 

 brown, with a broad golden margin ; side lobes of lip erect, truncate, midlobe white, 

 spur yellowish ; dorsal scale of spur broad erect; column and rostellum very short ; 

 strap of globose polliuia linear, with an apiculate tip. Trimen rightly suspects his 

 Thwaitesianum to be Lindley's decipiens. 



15. C. bicuspidatum, Hook. f. ; leaves 3-4 by |-1 in. acutely 2-fid, 

 raceme lax-fld. much shorter than the leaves, sepals orbicular-obovate obtuse, 

 petals oblong-obovate, side lobes of lip plicate truncate, midlobe very 

 stout ovate acute incurved, spur cylindric longer than the sepals obtuse. 



SIKKIM HIMALAYA ; near Darjeeling, Anderson (in Serb. Calcutt.). KHASIA 

 HILLS ; alt. 2000 ft., Mann. TENASSEEIM, Parish (Ic. in Hort. Calcutt.). 



Stem very short. Leaves flat, narrowed towards the base, lobes very acute, often 

 unequal, the longer in. Peduncle with 5-6-fld. simple or branched raceme 2-5 in. ; 

 bracts small, ovate; flowers |-f in. diam., spreading or reflexed ; sepals and petals 

 yellowish-green, with a median stripe ; lip white, speckled or flushed with rose, 

 spur longer than the sepals, mouth infundibular with a thickened ridge, dorsal callus 

 2-lobed ; column very short, rostellum long decurved ; anther beaked ; strap of 

 globose pollinia dilated upwards, tip rounded produced beyond the pollinia, margins 

 recurved, gland minute. 



SPECIES UNKNOWN TO ME. 



C. DISCOLOE, Lindl. in Sot. Reg. 1845, Misc. 59; leaves oblong channelled 

 obliquely truncate, peduncle long slender dull purple branched at the extremity, 

 sepals orbicular -ovate 5-nerved, and petals elliptic, both dull yellow with a greenish 

 tinge, lip 3-fid, side lobes plicate with a conical caruncle in the inner faces within, 

 dorsal tooth undivided keeled, spur longer than the sepals obtuse nearly white. 

 India (Hort. Loddiaes). In Lindley's fragment the leaf is 3| by nearly 1 in., the 

 very slender peduncle has some small ovate obtuse sheaths ; bracts small, broad, 

 membranous; fl. buds about ~ in. diam., membranous; spur cylindric, longer than the 

 broad sepals, walls thin ; side lobes of lip truncate, subcrenate ; midlobe very short 

 continuous with the side lobes, incurved, ovate, acute, concave, thin, without calli ; 

 callus below the column 2-lobed, puberulous; pollinia each didymous, strap clavate 

 with recurved margins, gland very small.
