Ceylon. This has pendulous stems like those of D. 



Pierardi, but of a delicate purple when young ; the leaves 

 too are stained underneath and at the edges with the 

 same colour. The flowers are as large as those of D. 

 aggregatum, of a clear fawn colour, with the tips of the 

 segments and lip stained with a deep rich violet. There 



is moreover a scarlet spot in the middle of the lip.

28. D. remlutum (lAn^X. in Bot. Reg. 1840, misc. 110); cau- 

 libus obtuse ancipitibus, foliis ovato-oblongis obtusis 

 apice obliquis emarginatis basi subcarinatis, floribus 

 solitariis oppositifoliis, sepalis petalisque acutissimis revo- 

 lutis, labello carnoso convexo obtuso subtrilobo aut 

 rhombeo per medium exarato (s. lamellis duabus inflexis 



parallelis instructo) lineis tribus discoloribus. Sinca- 



pore. Flowers straw-coloured, and about the size of 



those of D. Pierardi, but their lip is fleshy, convex, 

 almost lozenge-shaped, and marked with 3 brown lines. 



29. D. excisum (Lindl. in Bot. Reg. 1841. misc. 165) ; foliis 

 lineari-oblongis oblique retusis, floribus (solitariis ?) 

 oppositifoliis basi squamatis, sepalis .petalisque acumi- 

 natis, labello oblongo acuto carnoso basi utrinque exciso : 

 disco late glanduloso, cornu pedicello fere duplo breviore. 



Sincapore. A small species with the habit of D. 



pulchellum, but with white inconspicuous flowers. 



30. D. aqueum (Lindl. in Bot. Reg. 1843. misc. 6. t. 54) ; 

 foliis ovato-oblongis undulatis acuminatis, floribus pg,tulis 

 cornu brevi obtuso, sepalis petalisque ovatis, labelli tri~ 

 lobi pubescentis lacinia media ovata denticulata basi alte 

 excavata lateralibus latioribus rotundatis margine ante- 



riore serrulato. Bombay. With the manner of 



growth of D. Pierardi, the pale watery green flowers of 

 this are quite destitute of the attractive colours of that 

 gay species, and are entirely difl*erent in the structure of 

 the lip, which is furnished with a large cavity, almost a 

 pouch at the base of the middle lobe. It is also a much 

 stouter plant with wavy leaves. 



31. D. longicornu (Lindl. in Wall. Cat. no. 1997- Bot. Reg. 

 t. 1315. Gen. et Sp. Orch. no. 26) ; caulibus erectis 

 hispidis flexuosis, foliis ovato-lanceolatis apice valde 

 obliquis, floribus fasciculatis v. solitariis terminalibus, 

 bracteis ovatis acuminatis hispidis pedicello multo brevio-
