CALANTHE. 171 
The prevailing colour in the flowers is white; but the sepals are tipped with 
green externally, and the lip has a blotch of pale violet near the base, the large 
lobulate callosity however being bright yellow. 
Prate 230.— Calanthe alismefolia, Lindl. A plant; of natural sise. Fig. 1 a flower, 2 bract, 
staiked ovary, column and lip, in profile; 8 section through apex of ovary, stigma (s), column and 
lip, 4 front view of the column showing the callosity and the base of the lip, the eutrance to the 
spur (е), and the stigma (s-s.), 5 anther, 6 pollinia; all enlarged. 
10. CALANTHE ANGUSTA, Lindl. Fol. Orch., 7. 
Pseudo-bulbs coespitose, conical, only “2 in. long. eaves from the pseudo-bulbs, 
narrowly elliptie, acute, tapering to the sessile base; length 6 to 9 in., breadth 2 to 
3 in. Peduncle and raceme together 15 to 24 in. long; the peduncle stout, puberulous, 
bearing several lanceolate sheathing bracts 1 to 2 in. long; the raceme 4 to 6 in. 
long, many-flowered. Flowers 1 in. across, white; floral bract broadly elliptic, acute 
or sub-acuminate, rather shorter than the slenderly stalked ovary. Sepa’s elliptic, 
sub-acute, spreading. Pedals narrowly oblong, blunt, only one-half the width of the 
sepals. ip spurred, longer than the sepals, adnate to the column throughout the entire 
length of the latter; side lobes large, oblong, sub-faleate, their apices converging 
and overlapping the base of the apical lobe, sub-acute; apical lobe sub-reniform, its 
apex with two large sub-obovate blunt lobules separated by a deep triangular sinus; 
the upper surface bearing a cluster of small yellow calli between the bases of the 
side lobes and in front of the mouth of the spur. Spur slender, long, cylindric, 
slightly curved, puberulous, nearly as long as the stalked ovary. Column short; stigma 
divided into two elongated halves by the entrance to the spur; arms of the rostellum 
oblong, blunt and projecting beyond the lip of the anther. Pollinia shrunken, attached 
to a quadrate gland. Walp. Ann. VI, 916; Hook. fil Fl. Br. Ind. V, 849. | 
At the base of the range to the east of the Jaldacca river, at an elevation of 
about 800 feet; in flower during April; Pantling, No. 440. Khasia Hills; Lobb, 
Clarke. Manipur; alt. 3,500 feet, Watt. | 
The flowers, which are pure white and have a sweet smell, resemble those of 
C. odora, Griff, although the latter have a spur longer than the ovary, and the flowers 
and leaves are not contemporaneous as in this. The specimens of C. odora are very 
scanty, but an examination of them leads us to believe that €. odora and б, angusta 
are probably only different names for the same species. 
Prate 232.—Calanthe angusta, Lindl. .A plant; of natural size. Fig. 1 а flower; 2 floral bract, 
stalked ovary, column and lip with its spur, side view, 3 lip, 4 column with the anther in situ,

11. CALANTHE CHLOROLEUCA, Lindl. Fol. Orch., 10.

elliptic-lanceolate, acute, gradually tapering to the broad. sheathing petiole, not fully 
developed until after the flowering; length when adult 12 to 14 in., breadth 2:75 to 
4-5 in, petiole about 3 to 6 in.  Peduncle longer than the leaves, puberulous,
