bium, and its nearest ally appears to be the Ceylon species D. macros- 

 tachyum, Lindl. ; but in that species the margins of the lip are slightly 

 erose, not deeply firnbriate-serrate as in this ; the disc is naked in that, 

 or has only a few scattered hairs ; the nectary and anther are entire 

 in D. macrostachyum, and the flowers, which are sweet-scented, are in 

 racemes. 



Bulbophyllttm DEPRH3SSUM, n. spec. Pseudo-bulbs obliquely de- 

 pressed-ovoid, '25 in. long, produced at distances of *2 in. on a filiform 

 rhizome. Leaf sessile ; broadly ovate, acute, the apex shortly aristate, 

 length 4 in. Flowers *2 in. long, solitary, from the bases of the pseudo- 

 bulbs ; the ovary slender, about as long as the flower ; floral bract ovate, 

 acute, shorter than the sessile ovary. Sepals equal, linear-oblong, acu- 

 minate, connivent. Petals fleshy, less than half as long as the sepals, 

 oblong, slightly ob-lanceolate, acute. Lip shorter than the sepals, 

 decurved from the middle ; oblong, 3-lobed ; the lateral lobes erect, 

 large, broadly oblong, oblique, their edges irregularly dentate-serrate ; 

 apical lobe fleshy, blunt, entire, its base much thickened. Column very 

 short, only about half the length of the foot, without teeth. Pollinia 

 very unequal.

 Jaintia Hills ; elevation 3000 feet ; Pantling No. 627. 



The sepals of this interesting little plant are greenish, shading to- 

 wards the middle into dull purple : the petals and lip are of a uniform 

 dull purple. The species is closely allied to B. Listeri, a species describ- 

 ed in a former number of this Journal (Vol. LXIV, Pt. 2, page 334). 

 But that has a lip with no lobes, and its column has long subulate apical 

 processes ; its lip moreover is linear-oblong. It is also allied in habit 

 to B. Epicrianthes, Hook, fil., which has however totally different petals, 

 being thread-like and pendulous. 



Bulbophyllum Collettit, n. spec. King and Pantling. Pseudo- 

 bulbs oblong, "75 to 1 in. long, situated an inch and a half apart on a wiry 

 rhizome. Leaf solitary, elliptic-oblong, blunt, suddenly contracted at 

 the base, sessile ; length 1*5 to 2 in., breadth "4 to "6 in. Scope not 

 longer than the pseudo-bulb, bearing several sheaths and also 3 or 4 

 spathaceous bracts just under the 2- to 6-flowered terminal umbel. 

 Flowers pale yellow, 3 in. across ; floral bract spathaceous, lauceolate, 

 as long as the shortly stalked ovary. Sepals sub-equal, linear, acumi- 

 nate, the dorsal rather shorter. Petals lanceolate, finely acuminate, 

 slightly shorter than the dorsal sepal. Lip oblong-ovate, fleshy, with 

 a broad shallow triangular groove extending from the base nearly to 

 the apex. Column stout, the apex with two long subulate teeth ; stig- 

 matic surface large and excavated ; the foot as long as the column,
