222 ORCHIDS OF THE SIKKIM-HIMALAY 4. 
ilie removal of the pollinia from the anther, the caudicle (previously somewhat bent) 
` immediately falls forward to the. same plane as the gland, while the pollinia move in 
а reverse direction until they assume a position at right angles to the caudicle.

6. SACCOLABIUM OBTUSIFOLIUM, Hook. fil Ie. Plant., t. 2134. 
Stem pendulous, :35 in. thick and 4 to 6 in. long. eaves oblong, flat, somewhat 
tapered to the bluntly bilobed apex and slightly contracted to the jointed base; length 
6 to 8 in, breadth 1 to 195 in. Inflorescence from below the leaves ог leaf-opposed, 
longer than the leaves; the peduncle stout, with three or four short broad blunt sheaths; 
the raceme about as long as the peduncle, densely many-flowered. Flowers *5 in. across; 
foral bract oblong, blunt, more than half as long as the shortly-stalked ovary. Sepals 
obovate, blunt, sub-connivent, the dorsal concave. Petals broader than the sepals and 
somewhat shorter, blunt. Zip longer than the sepals, consisting mainly of a large very 
wide-mouthed infundibuliform sae much curved forward and bulbous at the apex; the 
side lobes on the edge of the mouth of the spur near the column, small, triangular; 
apical lobe thickened, laterally compressed, pouched and 3-lobulate; the two posterior 
lobules oblong, blunt, directed backwards; the middle one broadly triangular, acute and 
directed upwards. Column short, rostellum beaked. Anther tumid, with a long beak. 
Pollinia two, small, obliquely ovoid, attached by a curved process to the apex of the 
large caudicle; caudicle broadly cordate or 2-winged at the apex, narrowed below to 
the oblong-ianceolate gland. Capsule fusiform, :65 in. long. Hook. fil. Fl. Br. Ind.

The flowers are of a pale yellow tint, the apical lobe of thelip and the apices of 
the petals and sepals being of a brighter tone. The attachment of the pollinia to the 
caudicle and the shape of the latter are peculiar, and induced Lindley to form for 
the reception of all the species with the same arrangement the genus Uncifera. Тһе 
pollinia lie inverted and are attached to the end of a small curved process which 
proceeds from the apex of the caudicle. The caudicle is an elongated body broadly 
cordate or two-winged at the apex, and tapering to the point by which it is inserted 
on the large elongate gland. On removing the whole apparatus from the anther the 
wings of the caudicle close, but the pollinia retain their inverted position.
