membranous, ovate, acuminate ; the base rounded and passing abruptly 

 into the short loose sheath, 7- to 9- nerved ; length 3'5 to 5'5 in., 

 breadth 225 to 2*75 in. Inflorescence much longer than the leaves, 

 slender, striate; raceme as long as the ebracteate peduncle, few-flowered; 

 floral bract lanceolate, shorter than the slender • pedicelled ovary, re- 

 flexed. Flowers '4 in. long, pale-green with a shade of yellow, (fide 

 ■collector) their ovaries nearly "5 in. long. Sepals lanceolate, reflexed, 

 the dorsal narrower than the lateral pair. Petals linear ; their margins, 

 like those of the sepals, revolute. Lip deflexed from the very base, 

 flat, broadly obovate, the margins entire, the base with two small rouud- 

 ed calli. Column almost straight, not winged at the apex and not dilated 

 at the base. 



The nearest ally of this appears to be the North- West Himalayan 

 species L. rostrata, Reichb. fil., from which this however differs in 

 having an entire lip with two calli at its base, a more elongated pseudo- 

 bulb and almost sessile leaves. It also resembles L. deflexa, Hook, 

 fil., but differs from that in having nearly sessile broader leaves and 

 an entire lip. It belongs to the section Mollifolise.

 flowering in August ; Kurz (without flower) No. 345. 



Dendrobium Ritaeanum, n. spec. Stems slender, formed of chains 

 of slender pseudo-bulbs with fibrous remains of old sheaths at the 

 joints, branching; the branches consisting of sessile sub-cylindric 

 pseudo-bulbs about 1*25 in. long and '25 in. thick. Leaf solitary, from 

 the apex of the pseudo-bulb, lanceolate-oblong, sub-acute, 2*25 to 3*5 

 in. long, and *5 in. wide. Flowers '5 in. across, solitary on a very short 

 peduncle ; floral bract minute, triangular. Dorsal sepal ovate-lanceolate ; 

 the lateral pair falcate, -sub-acute. Petals oblong, shorter than the 

 sepals. Lip in general outline spathulate ; the lateral lobes small, 

 projecting, obliquely obtuse ; terminal lobe deeply divided by a blunt 

 apical sinus into two broadly elliptic blunt lobules ; the disc between 

 the lateral lobes occupied by a thickened purple area sub-spathulate in 

 shape and having a slightly raised mesial line. Column and its foot 

 rather long ; mentum short, wide. Clinandrium laciniate ; lip of anther 

 2-lobed. 



Khasia Hills ; elevation 3-4000 feet ; collected by Mr. Rita, after 

 whom it has been named. 



A species belonging to the Section Cadetia and allied to D. Macraei, 

 Lindl. ; but with pale yellow, instead of white, flowers and with much 

 smaller leaves ; also having a very different lip from that species and 

 more slender pseudo-bulbs.
