Stem slender. Leaves 2-4 in., rather thickly coriaceous, very variable in width, 
rarely pubescent or tomentose on both surfaces; nerves few, spreading ; petiole 4-4 
in. Cymes always more or less pubescent, hispid at the bases of the umbels. Corolla 
in. diam., dull yellow and purple within. Follicles very variable, poniard-shaped, 
divaricate, 3—4 in. and slender in Deccan specimens with a thin pericarp; turgid in 
the lower half, and only 2 in. long, with a thick pericarp, in some Ceylon specimens. 
Seeds } in. long, broadly ovate,

peduncles long stout branched bearing few-fld. irregular umbels or clusters, 
sepals ovate pubescent, corolla subglobose fleshy shortly 5-lobed, coronal 
processes gibbous with free cuspidate tips (or 0), follicles very large ellipsoid 
ventricose. Gymnema Wallichii, in part, Wight Contrib. 46. G. sagittatum,

Leaves thickly coriaceous, 4-6 by 3-2 in., narrowed at the cordate base, nerves 
spreading; petiole 4-3 in. Cymes often exceeding the leaves, branches divaricate. 
Flowers } in. diam.; often fleshy and deformed with the column imperfectly developed 
cylindric and without coronal processes. Follicles very different from those of any 
congener, 4-5 by 1-1} in., elliptic-lanceolate, narrowed equally to the base and tip, 
pericarp coriaceous. Seeds } in. long, broadly ovate.—This very closely resembles in 
habit when dry Gongronema Wallichii. 
37. TREUTLERA, Hook. f. Gen. Nov. 
A stout glabrous twiner. Leaves opposite, thickly coriaceous. Flowers 
large, in axillary simple stoutly peduncled umbels. Sepals very small, ovate, 
glandular within. Corolla rotate, shortly 5-lobed ; lobes broadly ovate, cilio- 
late, overlapping to the right. Coronal processes adnate to the backs of the 
anthers and equalling them, ovate, obtuse, fleshy. Column prominent ; anther- 
tips inflexed, rounded ; pollen-masses one in each cell, subcylindric, pedicelled, 
waxy, erect. Stigma hemispheric, 2-cuspidate, included.

Branches terete, smooth. Leaves in distant pairs, 3-5 by 13-3 in., ovate elliptic 
oblanceolate or elliptic-oblong, apiculate or acuminate, midrib thick ; nerves 4-5 pairs, 
spreading, secondary indistinct; petiole stout, j-1j in. Peduncle 1-2 in.; pedicels 
1-1} in, stout ; bracts small, lanceolate. Sepals ciliate. Corolla 1-14 in. diam., 
coriaceous, glabrous, dark purple. Fruit not seen.— This genus is very near Marsdenia, 
from which it differs conspicuously in the large rotate corolla with short rounded 
lobes. It is named after Dr. Treutler, a native of the rovince of Sikkim, who pre- 
sented to Kew in 1875 a very large and valuable collection of its plants, inclusive of 
the present which is one of the most handsome of the Sikkim Asclepiads.
