CALANTHE. 169 
Sikkim, at elevations of 6,000 to 8,000 feet; in flower during May and Juno; 
Griffith (Kew Distrib.), No, 5278; Pantling, No. 317. Nepal; Wallich. Kamaon; T. 
Anderson. Bhutan; King’s collector. 
The colour of the flowers is dull purple or brick red, relieved by lines of white 
on the midribs of the sepals and petals and on the edges of the lip; while the lamellz 
of the lip have streaks of yellow on them, Тһе outer surfaces of the parts of the 
flower are all strongly flushed with white. A colour variety is occasionally found in 
which the dull purple of the perianth gives place to yellow, there being no difference 
structurally and both forms sometimes occurring on the same plant. The mouth of the 
short spur is lined with retroflexed hairs.

7. CALANTHE BILOBA, Lindl. Fol, Orch., 3. 
Pseudo-bulbs stout, cylindric, stem-like, 6 to 8 in. long. Leaves several towards the 
apex of the pseudo-stem, unequal, the lower short and sheath-like, broadly elliptic, 
shortly caudate-acuminate, undulate, tapering to the broad sheathing petiole ; length of 
blade of upper leaf 8 to 12 in., breadth 2*5 to 4 in.  Aacemes 1 or 2 from the axils of 
the lowest leaves, measuring with their long peduncles 18 to 30 in. in length (the 
raceme forming one-third), minutely puberulous. Flower 1:5 in. across (vertically); floral 
bract lanceolate, acuminate, shorter than the stalked ovary, the lower bracts longer 
than the upper. Sepals sub-equal, spreading, broadly ovate-lanceolate, caudate-acuminate ; 
the lateral pair faleate, rather narrower than the dorsal. Petals shorter and narrower 
than the sepals, oblong, with somewhat expanded triangular apices. .Lip longer than 
the sepals, with a short conical spur арӣ’ a long narrow claw; its lamina broadly 
ovate-oblong, deeply 2-lobed ; the lobes sub-rhomboid, acute, deflexed, their margins 
slightly undulate ; the sinus narrow with an acute apiculus; the upper surface with 
three shallow ridges towards the base. Column short, stout.  Aniher apiculate. Рота 8, 
unequal, narrowly oblong, attached by long stalks to a small transparent elliptic gland. 
Walp. Ann. VI, 912; Hook. fil. Fl. Br. Ind. V, 848. 
Sikkim, rather common in shady places, at elevations of from 3,500 to 7,000 feet; 
Pantling, No. 50. Also in East Nepal; Sir J. D. Hooker; in flower during September 
and October. 
The ovary and anterior portion of the lip of this are usually pale violet, the 
claw of the lip being whitish, The whole of the sepals and the petals, except their 
triangular apices, are ochraceous yellow beautifully mottled with purplish-brown; the 
column is tipped with dark brown, and the spur is pink. This colouration is, however, 
not constant. The wide mouth of the spur is lined with hairs which point downward. 
The raceme here figured is in a far-advanced stage; while young, the raceme is much 
more condensed and is pyramidal with a drooping apex. In this species the limits of 
the three stigmas which are united in the column and rostellum are marked by faint 
lines. 
` Prare 228.—Calanthe biloba, Lindl. Blade of a leaf and a raceme; of natural size; outline of 
an entire plant; much reduced. Fig. 1 а flower, 2 bract, ovary, column with anther in situ, and 
lower part of lip with spur, 3 section of the foregoing, 4 anther, 5 pollinia; all enlarged.
