12 PEOFESSOE LlJfDLEY's CONTEIBUTIONS TO 



each other that it is scarcely possible to find good distinctions 

 for them. Even when seen alive in their natural state, the uncer- 

 tainty is the same. " All the species," says Griffith, " with cochle- 

 ate labella are nearly akin ; they run into each other so much, 

 that distinguishing marks are very difficult." (Itinerary Notes, 

 p. 185, speaking of a form of Dendrobmm nohile found at Panukka 

 in Bootan.) 



103. D. pulchellum, Lindl, Gen. 8f Sp. No. 35 ; Bot. Cab, t. 1935. 

 (D. brevifolium, Hort. D. Devonianum, Pawfon, B. M. t. 442.9. D. 

 pictum, Griffith.) 



Khasija, J. D. H. (15); Bootan, Griffith. 



I have this from Bootan from Griffith, under the name of D. 

 pictuTiiy but have failed to discover any trace of it in his Itinerary 

 Notes. 



104. D. Pierardi, Boxb. Fl. Ind. 3. 482. 

 Valleys of Sikkim, Cathcart ; J. D. H. (5). 



105. D. primulinum, Lindl. in Gard. Chron. 1858, no. 223. (D. nobile 

 palHdiflorum, Bot. Mag. t. 5003.) 



Hot valleys of Sikkim, J. D. H. (154). 



Possibly this is not distinct from D. cucullatum, as is suggested 

 in the work above referred to. 



106. D. transparens, Wallich, Cat. No. 2008. (D. Henshalli, Bchb. f.; 

 Bot. Mag. t. 4663.) 



Sikkim, at 2000 feet, J. D. H. (153) ; on rocks towards Chuka, in Bootan, 

 and near Murichom, at 3500 to 4000 feet, Griffith. 



I am unable to distinguish the Sikkim specimens from this 

 plant, although they are somewhat larger than such as have ap- 

 peared in our gardens ; there can be no doubt that it is the No. 

 1135 of ' Griffith's Itin. Notes,' p. 198, and Prof. Echb. has himself 

 pointed out the identity of his D. Henshalli. 



107. D. amoenum, Wallich, in Lindl. Gen. c^' Sp. Orch. p. 78. 

 Sikkim, Cathcart (Jc). 



This is readily known by its narrow, blunt, nearly equal sepals 

 and petals, each with a purple stain at the point. 



108. D. nobile, Lindl. Gen. Sf Sp. Orch. 24. (D. cserulescens, Lindl. 

 Serf. Orch. t. 17.) 



Khasija, Griffith, J. D. H. ; Darjeeling, Griffith ; Assam, Id. 



Evidently variable in the size, and probably in the colours, 

 of the flowers. It is the No. 940 of Griffith's Itin. Notes, p. 184.
