238 ORCHIDS OF THE SIKKIM-HIMALAYA. 
AErides rostratum. In 1882 Lindley published in the Botanical Register his genus Micropera, to which 
he referred Roxburgh’s rides pallidum. In 1851 Dalzell, oblivious of Lindley’s genus of the same 
name, published in Hooker’s Journal of Botany his genus Micropera, and under it he described two 
species (М. viridiflora and М. maculata), one of which (М. viridiflora) is, according to Lindley and 
Sir Joseph Hooker, a Saccolabium. The other (JM. maculata) is also considered a Saccolabium by 
Messrs. Bentham and Hooker. Lindley, however, kept up Dalzell’s name for the latter, as he had in 
the meantime discovered that his own JMicropera is identical with Camarotis, to which he therefore 
himself reduced it (Journ. Linn. Soc. ПІ, 38). Camarotis is allied to Stereochilus, from which it is, 
however, at once distinguishable by its dorsal anther, differently shaped lip, and elongated stems. 
Sepals and petals broadly oblong; the lateral sepals connivent under 
the lip and partly adherent to it; flowers “75 in. across . . . 1. C. obtusa. 
Sepals and petals obovate, free, spreading; flowers "25 in. across . . 2. C. Mannii. 
1. CAMAROTIS OBTUSA, Lindl. in Bot. Reg. 1844, Mise. 73. 
Stem stout, erect, leafy, 8 to 10 in. long. Leaves coriaceous, horizontal, linear-oblong, 
slightly and obliquely bifid at the apex, not narrowed at the base, jointed to the short 
sheath; length 2 to З in., breadth “8 to ‘65 in. Racemes leaf-opposed, rigid, horizontal, 
about as long as the leaves when in flower, slightly longer in fruit; the peduncle with a 
few short sheaths; raceme with about ten flowers of which only two to four open at a time. 
Flowers (from the tip of the dorsal вера! to the tip of the lip) ‘75 in. across; бғас% small, 
ovate, acute; rachis of raceme, ovary, and exterior of sepals sparsely furfuraceous. Sepals 
unequal, reflexed, the dorsal broadly oblong, its edges towards the apex reflexed; the 
lateral pair larger, oblong, sub-falcate, obtuse, adnate for about a third of their length 
to the sides of the lip, and for the rest connivent under it. Petals oblong, blunt. Lip 
fleshy, adnate to the base of the column and forming with it a right angle, its anterior 
wall cut away in the upper part, the apical half conical, its cavity partly occluded by 
two large calli from the back and front walls, the latter sending a septum across and 
dividing the cavity into an upper and a lower chamber; the latter chamber nectariferous, 
the side lobes along the mouth of the spur narrow and incurved; the apical lobe minute, 
narrowly triangular, also incurved. Column short; the rostellum very long, hooked at the 
apex, and twisted to one side. Anther depressed, beaked; pollinia four, plano-convex, 
sub-orbicular, attached by pairs to the long tapering slender caudicle; gland small, sub- 
rotund. Capsule linear, ridged, 15 in. long. Reichb. fil. in Walp. Ann. VI, 881. 
Sarcochilus obtusus, Benth. MSS. ex Hook. fil. Fl. Br. Ind. VI, 36. Camarotis obliquirostris, 
Parish MSS. 
Sikkim, in tropical valleys at low elevations; flowering during August; Pantling 
No. 48. Tenasserim ; Parish. 
The flowers of this in Sikkim are white, the lip having a large yellow spot in front. 
The flowers originally sent to Lindley, and on which he founded his б. obtusa, were 
however described by him as of a dull dirty rose colour. 1% is therefore possible that 
the Aem of that species to this is incorrect.
