Coelogyne is here preferred. Should Chelonistele be 
ultimately retained, however, the name Chelonistele perak- 
ensis will apply to the present plant. - Pfitzer does not 
cite either the Perak plant or the Flora of British India 
under his Chelonistele sulphurea, so probably did not include 
it, but the only other species with which it could be con- 
fused are Coelogyne tenuiflora, Ridl., a native of Borneo, and 
C. lurida, L. Lind. and Cogn., whose habitat is not recorded. 
Both are figured, however, and as Ridley treats the former 
as distinct, while the latter has the bracts and side lobes of 
the lip relatively twice as broad, the only possible course is 
to consider the present one as distinct. 
The Javan Coelogyne sulphurea, Reichb. f., has long been 
cultivated at Kew, and in 1903 the Malayan plant was 
received fron: the Royal Botanic Garden, Glasnevin, under 
the same name. The two species flowered together during 
January of the present year, thus affording an opportunity 
of clearing up the confusion between them. 
Descriprion.—Epiphyte, 1-1} ft. high. Pseudobulbs 
approximate, ovoid-oblong, 14-2 in. long, 1-leaved. 
Leaves long-petioled, oblong-lanceolate or narrowly ellipti- 
cal, subacute, coriaceous, 5—7 in. long; petiole 2-4 in. long. 
Scapes erect, borne with the young growths from the base 
of the old pseudobulbs, $-2 ft. high, the basal half covered 
with imbricating brown sheaths; raceme lax, many- 
flowered. Bracts linear, acute, soon reflexed, and decidu- 
ous, 3-1 in. long, rose-pink. Pedicels slender, nearly 4 in. 
long. Sepals spreading, lanceolate-oblong, subobtuse, some- 
what concave, about $ in. Jong, light buff. Petals linear, 
obtuse, revolute, rather shorter than the sepals, light green. 
Lip strongly 3-lobed, rather shorter than the sepals; light 
rellow with a deep yellow blotch on the dise; side lobes 
inear, slightly falcate, obtuse, spreading ; front lobe obcor- 
dately 2-lobed, with broad obtuse segments; disc with a 
pair of smooth fleshy keels. Column clavate, broadly 
winged, somewhat curved, less than half as long as the lip. 
Pollinia 4, attached to a broad viscus—R. A. Roure.
