Veiy near E. obliquum Blujie ; it is impossible to find the distinction 

 between that species and our new one without dissecting flowers, so much closely 

 do they resemble in appearance. The differeuce hetween thcm is shown as 

 follows : 



i?. obliquum 

 Corolla-tube cylindric contracted 

 at the mouth, lower lip of the co- 

 rolla 3-lobed ; stigma minutely 2- 

 lobed. 



R. holoqlossum 

 Corolla-tube cylindric not at all 

 contracted at tlie mouth, lower lip of 

 tlie corolla entii'e, not lobed; stigma 

 globose entire, not lobed. 



Clarice says, iu Hook. f. Fl. Brit. Ind. IV. ]}. 367, " Lcaves (of R. ohliquum) 

 1-^in."; but this could never be the case witli any species of the genus. I 

 presume this is due to a misprint. 



R. ohliquum Blume var. parvijlora Clarice {=R. zeylanicum HooK. iu Bot. 

 Jlag. t. 4198) agrees fairly well witli om- R. Iiologlossum; the only difference is 

 that in the former the lower lip of the coroUa is 3-lobed, while in the latter 

 the lip is entire. lu respect of the relativc length of the lips and the 

 corolla-tubes, tlie uew species accords very well with R. zeylanicum Hook. 

 HooKER says in the note of Bot. ]\Iag. t. 4198 that "tlie geuus is Loxotis of Mr. 

 Brown, in Horsfield's Plants of Java, Fasc. I. p. 102, t. 24, and the specie-s 

 there admirably figured and described, so much resembles the present one, that 

 at first I was unwilling to consider them distinct ; but in all tlie many 

 flowers I have examined, there is uniformly in our plant such a difterence in 

 the lower lip, short and broadly ovate, uot twice tlie leugth of the uppcr liji, 



and shorter thau the tube in Mr. Brown's Loxotis obliqua oblong or strap- 



shaped, longer even than the tube of the corolla, obscurely tridentate, that I 

 cannot but describe thc present as new." As is seen in the statements made 

 by HooivER, our plant is nearer to R. zeylanicum thau to R,. dbliquum. Still, 

 ours is difierent from R. zeylanicum in having entre lower lip of the corolla.
