SACCOLABIUM. 223 
7. SaccoLABIUM AcuMINATUM, Hook. fl le. Plant; t. 2195. - 
Stem slender, pendulous, 6 to 9 in. long, clothed below with the narrow tubular 
sheaths of fallen leaves. Leaves linear-oblong, slightly narrowed to the sheathing base; 
the apex acuminate, not bifid; length 1:35 to 3 in, breadth ‘3 to “5 in. Racemes 
leaf-opposed, rather shorter than the leaves, 8- to 12-flowered. Flowers ‘25 in. across, 
crowded; floral бас? ovate, acute. Sepals ovate-rotund, the dorsal concave. Petals 
broader, oblique, sub-truncate. Lip consisting chiefly of an infundibuliform spur longer 
than the ovary and boldly curved forwards; side lobes rather large, rounded, erose ; 
apical lobe very fleshy, broadly triangular. Column short, thick; the rostellum large, 
projecting; pollinia globose, attached to a thick hooked process proceeding from the apex 
of the caudicle; caudicle with two broad shoulders at its apex, gradually tapering to 
the narrow pointed gland. Hook. fiL Fl. Br. Ind., VI, 63. Uneifera acuminata, Lindl.

The flowers are of a pale green, almost white on the anterior lobe of the lip and 
on the tips of the petals. On removing the pollinia from the anther, the caudicle falls 
forward suddenly to the same plane as the gland, and the curved process at its apex 
to which the pollinia are attached, is then seen to consist of a folded membrane which 
opens along the upper margin and slightly separates the two masses. This species is 
rare in Sikkim, only a single specimen having as yet been collected. It is, however, 
common in the Khasia Hills. This is allied to Ж. obtusifolium, but is a more slender 
plant with shorter, narrower, entire, acuminate leaves and smaller paler flowers.

Vol. LXV, pt. 2, 122. 
Stem slender, pendulous, 8 to 12 in. long. Leaves fleshy, linear, acuininate, aristate 
at the apex, slightly keeled, 3 to 5 in. long and ‘25 to'3 in. broad. Racemes axillary, 
densely-flowered, 1:5 to 2 in. long, their peduncles as long as themselves and bearing 
` а few membranous lanceolate scattered bracts. Flowers 79 in. across; floral bracts minute, 
triangular, much shorter than the short ovary. Dorsal sepal broadly ovate, very concave, 
its apex broad and slightly emarginate ; the lateral pair obliquely obovate, blunt, all three 
connivent. Petals oblong, blunt. Lip boat-shaped, its limb about as long as the sepals, 
the apex very fleshy, blunt. Spur funnel-shaped, longer than the ovary, much curved 
forwards, its apex not thickened. Column very short, the rostellum beaked. Peollinia two, 
globular-ovoid, attached to the inflexed beak of the caudicle; caudicle broad below the 
beak, much narrowed to the base; gland elongate, notched at its base. 2.
