120 G. King &. R. Pantling — New Orchids from Sikkim. [No. 2, 



from 1*25 to 1*75 in. Pseudo-bulbs none. Leaves sub-coriaceous, oblanceo- 

 late or oblanceolate-elliptic, blunt and minutely bifid at tbe apex (some- 

 times obliquely so) much narrowed to the base ; length 2-2*25 in. breadth 

 •75 in. Scapes erect, filiform, slightly exceeding the leaves and bearing one 

 or two small sheathing bracts, the flowers in a terminal capitulum ■35 in. in 

 diam. Floral bract one half as long as the shortly-stalked ovary. Flowers 

 •1 in. in diam., dorsally flattened, fleshy, and of a dull purple throughout. 

 Sepals 3-neryed ; the dorsal broadly triangular, acute, concave and 

 covering the column ; the laterals ovate, acute, spreading. Petals 

 oblong, oblique, acute, 1 -nerved. Lip tumid, broadly ovate, convex, 

 papillose, the basal portion rectangular and deeply grooved ; column 

 with broad falcate arms having a short soft tooth at the end of each. 

 Anther flattened, pollinia in ovoid pairs. 



Sikkim Himalaya: at an elevation of 1,500 feet, flowering in 

 September and October. R. Pantling No. 242. 



This species, although quite distinct from B. xylophyllum, Reich b. 

 fil. is allied to it. The latter has more coriaceous leaves with broad blunt 

 emarginate apices. 



IONE, Lindl. 



Ione intermedia, n. spec. Rhizome less than "1 in. thick, smooth. 

 Pseudo-bulbs '5 in. long, ovoid, semi-transparent, less than 1 in. apart, 

 each bearing a single sessile linear leaf notched at the apex 2 to 4 in. 

 long and '25 in. broad. Scape slightly longer than the pseudo-bulb, 

 zig-zagged, enclosed at the base by two or three sheaths and bearing 

 1 to 3 flowers. Floral bracts lanceolate, equalling or longer than the 

 shortly-stalked ovary. Flowers pale green, *5 in. long. Sepals lanceo- 

 late, spreading, "25 in. long, the laterals lying under the lip and coher- 

 ing by their tips. Petals linear, more or less twisted and with broad 

 dilated serrate bases. Lip sessile, slightly shorter than the sepals, 

 lanceolate- acuminate ; the base dilated, slightly concave and with small 

 rounded lobes. Column rather broad, with narrow wings near the 

 middle. Rostellum elongated, deflexed. Pollinia 4, attached in pairs to 

 two strap-shaped caudicles ; gland reniform. 



Sikkim : at Tendong, elevation 6,000 feet ; flowering in June. 

 Pantling No. 161. 



The attachment of the pollinia in pairs to the large, stiff, strap- 

 shaped caudicles — so different from the arrangement in Bulbophyllum — 

 appears to us a character of sufficient importance to warrant the reten- 

 tion of lone as a genus. In Bulbophyllum (to which lone has been 

 reduced) there is no caudicle. This is not, however, the only distinc- 

 tive character ; for, in lone, the lip is sessile and firmly attached to the
