CALANTHE. 173 
the lower halves being green. This species is very closely allied to €. chioroleuca, Lindl., 
but differs from it in having fewer flowers in its raceme, somewhat larger floral basis 
and a much longer spur. Moreover in this the apical lobuli of the lip are entire, narrowly 
oblong and diverging; while in C. chloroleuca these lobuli are crenate, broad, rounded, 
and not diverging. 
The flowers of this are inodorous, while those of €. chlorantha ате 
delightfuily fragrant.

13. CALANTHE Masuca, Lindl. in Wall. Cat. 7337; Gen. and Spec. 
Orch., 249. 
Pseudo-bulbs narrowly conical, with annular scars, 2 to 3 in. in length.  Leares 
more or less broadly elliptic, acute, narrowed at the base into a petiole, or sessile; 
length 6 to 15 in., breadth 2:75 to 4:25 in.; petiole 2 to 6 in., or 0. Peduncle exceed- 
ing the leaves in length, stout, with two or three scattered acute lanceolate bracts. 
Raceme about 6 in. long, many-flowered, pubescent. Flowers rather crowded, depressed, 
2 in. across, with a curved slender cylindric spur longer than the ovary; bract ovate- 
lanceolate, concave, shorter than the puberulous stalked ovary. Sepals elliptic or elliptic- 
lanceolate, acute, spreading, the lateral pair slightly longer than the dorsal. Petals smaller 
than the sepals, sub-acute. Lip as long as the sepals, attached to almost the whole length 
of the column, 3-lobed ; the basal lobes oblong, blunt, sub-falcate, directed forwards ; apical 
lobe large, sub-rhomboid, or cuneately reniform, deeply emarginate at the apex; the disc 
between the side lobes with three unequal elongate tubercular calli. Column very short. 
Stigma in two halves and the rostellum consisting of two projecting plates. Anther pointed. 
Pollinia 8, sub-equal, clavate, sub-sessile on a small oblong gland. Capsule elliptic, 1:5 
in. long. Lindl. in Bot. Reg., 1842, Misc., 51; id. 1844, t. 37; Fol. Orch., 6; Bot.

Sikkim, common at elevations from 1,500 to 4,000 feet; in flower dating August 
and September; Pantling, No. 39. Тай westward along the range to Nepal; 
also in the high lands of the Deccan, the Western Ghats and in Java. | 
The flowers are of an almost uniform violet tint, becoming of a rusty colour 
when beginning to wither. The calli on the lip are yellow. The coloration, however 
varies. In the form which was named С. versicolor the perianth is white, the lip 
being purple, changing to yellow. In another form the sepals are crimson and the т 
deep purple. The latter variety does not, however, occur in Sikkim.
