Very near R. obliquum BLUME ; 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 difference between them is shown as 

 follows : 



R. obliquum 



Corolla-tube cylindric contracted 

 at the mouth, lower lip of the co- 



rolla 3-lobed ; stigma minutely 2- 

 lobed. 



R. hologlossum 



Corolla-tube cylindric not at all 

 contracted at the mouth, lower lip of 

 the corolla entire, not lobed; stigma 

 globose entire, not lobed. 

 CLARICE says, in HOOK. f. Fl. Brit. Ind. IV. p. 367, " Leaves (of R. obliquum) 

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

 presume this is due to a misprint. 



R. obliquum BLUME var. parviflora CLARKE (=R. zeylanicum HOOK, in Bot. 

 Mag. t. 4198) agrees fairly well with our R. hologlossum} the only difference is 

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

 the lip is entire. In respect of the relative length of the lips and the 

 corolla-tubes, the new species accords very well with R. zeylanicum HOOK. 

 HOOKER says in the note of Bot. Mag. t. 4198 that "the genus is Loxotis of Mr. 

 BROWN, in HORSFIELD'S Plants of Java, Fasc. I. p. 102, t. 24, and the species 

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

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

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

 the lower lip, short and broadly ovate, not twice the length of the upper lip, 

 and shorter than 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 the present as new." As is seen in the statements made 

 by HOOKER, our plant is nearer to R. zeylanicum than to R. obliquum. Still, 

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