THE ORCIIIDOLOGT OP INDIA. 41 



2.36. A. cylindriciim, Lindl I.e. ; Wight, Ic. 1744; Bot. Mag. 4982. 

 Nilgherries, J.D.H. (210); Sikkim, at 5000 feet, Id. (210). 



237. A. tseniale, Lindl. i.e. (Aerides carnosum. Griff. Not. t. 338 A.) 

 BootaD, Griffith ; Khasija mountains, up to 3000 feet, J. D. H. Sf T. T. 



(191). 

 "Elowers pale lilac," J. D. II. In the Khasija specimens the 

 leaves are from 4 to 5 inches long, and 1 to 1^ inch broad. 



238. A. affine, Wallich, Cat. no. 7316; Sertum Orch. 1. 15; Bot. Mag. 

 t. 4049, bad. (A. roseum, Loddiges; Paxton, Fl. Gard. t. 60. — A. 

 trigonum, Klotzsch,Jide Rchb.f.) 



Plains of E. Bengal and Assam, J. D. H. ^ T. T. (185); Assam and 

 Bootan, Griffith. 



Among the many specimens I have seen, flowers have occurred 

 in drooping and upright racemes, deep crimson and pale rose, 

 with the lip and other parts acute or obtuse, all which are there- 

 fore marks of one and the same variable species. 



239. A. odoratum, Loureiro. 



Base of Khasija, up to 2000 feet, J.D.H. Sf T. T. (182); Garden of 

 Sabarunpore, Id. ; Sikkim, in low valleys, J. D. H. 



240. A. crispum, Lindl. Gen. ^ S,p. Orch. p. 239 ; Bot. Reg. 1842, t. 

 55; Bot. Mag. t. 4427. (A. Brookei, Bateman, in B. R. 1841, misc. 

 116. — Saccolabium speciosum, Wight, Ic. t. 1674.) 



Concan, Law, in hb. Hooker. (268) ; Dalzell, in hb. Stocks. (75). 

 Several varieties of this beautiful plant are in our gardens. 

 The flowers in A. Brookei are rather smaller than usual. 



241. A. Lindleyanum, Wight, Ic. t. 1677. 



" On clefts of rocks bordering the Kartairy falls below Kaitie ; also on 

 rocky clefts on a high hill over Coonoor, flowering nearly the whole 

 year," R. Wight-, Nilgherries, T. T. (208). 



One of the finest of its order, the flowers being larger than in 

 either A. crispum ov falcatMin, and in larger more branching pa- 

 nicles. For this reason the localities given by Wight are stated 

 exactly, in the hope that some collector may send it home. In 

 front of the opening into the spur stands a pair of large curved 

 tubercles, which have not been observed in A. crispum. 



242. A. difforme, Wallich, in Lindl. Gen. ^ Sp. 242. 

 Khasija, at 3000-4000 feet, J. D. H. Sf T. T. (204), Griffith. 



This, which is the plant that Wallich had before him, seems to 

 diff'er from the following in having smaller flowers, with the 

 middle lobe of the lip only 2-lobed, the basal ones longer and a 

 little undulated, and the leaves more tapering to the base. This 

 I learn in part from careful dissection, and in part from one of
