THE ORCHIDOLOGY OF INDIA. 17 
127. D. ATTENUATUM ; foliis linearibus gramineis patentissimis, flo- 
ribus solitariis squamulis minutis obtusis, sepalis petalisque obtusi- 
usculis, mento lineari obtuso, labelli elongati spathulati lobis lateralibus 
dentiformibus intermedio subrotundo margine carnoso medio sub- 
aspero tuberculis geminis linearibus. 
Borneo, T. Lobb. 
Flowers small, apparently white. Leaves long, narrow, and 
grassy. Stems slender, ascending, from 6 to 8 inches high. 
* «* The only other species of this section аге D. calcaratum (Bot. 
Reg. 1840, misc. 218) and D. nutans (Gen. & Sp. Orch. No. 73), 
whose lip is not undivided as it was supposed to be, but lanceolate 
with short entire lateral lobes and a crisp, almost linear, middle 
part, as I learn from specimens communicated by my learned cor- 
respondent Mr. Thwaites (156). 
§ VIII. Peptroxnum, Blume. 
No continental species of this section have been observed, по? 
have I found among the collections examined by me anything like 
Roxburgh's D. purpureum, a Molucca plant. The following are 
new insular species. 
128. D. AUROROSEUM (Rchb. f. in litt.); folis angustis ovato-lan- 
ceolatis acutis, sepalis petalisque sequilongis acutis, mento elongato 
obtusissimo, labello nudo oblongo spice dilatato retuso utrinque 
reflexo ungue unituberculato. 
Java, T. Lobb; Zollinger (231). 
The oval lip, suddenly expanded into a broad apex reflexed on 
each side, and the extremely broad mentum, are like nothing else- 
where in this section. The flowers are the size of D. Pierardi. 
129. D. BunsIGERUM ; foliis oblongis acutis, spicis cylindraceis densi- 
floris, sepalis petalisque acutis, mento arcuato infra apicem ventricoso, 
labello spathulato acuto cucullato. 
Philippines, Cuming. 
Like D. secundum, but flowers are not half the size, and in 
longer, slenderer, not secund spikes. Lip apparently white with 
an orange-yellow tip. 
130. D. Rernwarpt!; foliis anguste oblongis obtusis apiculatis, spicis 
densissimis brevibus, bracteis setaceis divaricatis, sepalis acutis, petalis 
Obtusiusculis, mento duplo longiore apiculato, labello nudo angusto 
spathulato obtusiusculo. 
Banda, Reinwardt. 
Near D. viridirosewm of Rchb. f., from which it differs in its 
LINN. PROC.— BOTANY. с
