An erect glabrous, stout and branched herb 1-2 m. high. 
Stem groved, nodes prominent and sometimes ‘rufous in colour. 
Leaves ovate- lanceolate, oe 10-13 cm. exclusive of the 
petiole which is 1-25-2 5 ¢ long. Two stipular glands at the 
base of the petiole. Witendé simple, 5 lng on from the axils of 
the leaves, 10-13 cm. long; the pedicels 1-2 cm. in length, alter- 
nate from the peduncle. Bracts caducous, large, white, com- 
pletely ito at — young flower. Sepals 2, ovate, cordate, 
acuminate, mauy colour. Corolla 3-5 cm. in length, inty 
mauve in colour, Biotiched with yellow and dark purple. Standard 
orbicular, wi ithout keel. W ings with lateral lobes pie the 
terminal narrow with no dilatation or depression on the margin. 
Lip with a slightly curved slender spur. Pollen pinkishwievs 
in colour. Capsule linear. Seeds glabrous, average number 
found in 5 capsules 9-8. 
Fertilised by bees. This is most interesting to me for it is the 
first species collected in these parts that has large caducous bracts 
that are of sufficient size to protect the flower while in bud, and 
it is a distinct link between the groups into which I have divided 
the majority of the genus in this range. It possesses the typical 
open mouth of the one group, while at the same time it has no 
auricular lobe and its capsule is clavate.

Kachin Hills. Sinlum; 2200- m., in sunny situations 
near the top of one hill only, on which it grows in dense patches. 
Toppin 2744. 
The colour of all plants seen was of the same deep claret colour. 
The mouth of the flower is closed by the convergent terminal lobes 
of the wings. Bees usually settle on the lip and pierce the 
extremity, thus robbing the honey.
