Stem 8-10 in., often with 3-4 petioled leaves in a whorl in its middle and 2 sessile 

 leaves at its apex. Leaves coriaceous, base often unequally cordate, glabrous beneath 

 or minutely pubescent on the nerves. Rays of the cyme and pedicels subumbellate, 

 less viscous-hairy than in D. pulchra. Calyx in., nearly glabrous. Corolla very 

 sparsely hairy, purple. Capsules slightly curved ; pedicels in. Otherwise as D. 

 pulchra, 



VAR. attenuata ; leaves less coriaceous often cuneate at the base, cymes slenderer, 



bracts narrower, calyx scarcely | in., capsule slender pedicel filiform very long. 



Khasia Mts., alt. 3-5000 ft., especially in the northern portion of the hills ; Griffith, 

 H. f. <$ T., &c. This may be specifically distinct, for both the capsule and calyx 

 differ, but there are intermediate examples. 



16. D. Hookeri, Clarke Comm. &f Cyrt. Beng. t. 54 ; stem and petioles 

 villous, leaves ovate crenulate softly villous above glabrate (except the

Stem 16 in., with usually 3-4 petioled verticillate leaves in the middle, uppermost 

 leaves subsessile. Leaves 4 by 3 in. (sometimes much larger), subobtuse, often cor- 

 date; petiole |-3 in. Cymes sparsely hairy; bracts in., round; pedicels 0-J in., 

 usually short. Cali/x \ in., campanulate. Corolla tubular, pale yellow with rose-

KHASIA MTS.; alt. 4000 ft., near Churra, Wallich, J. D. H. $ T. T., &c. 



Stem 6 in., hairy; nodes 1-3. Leaves opposite alternate and verticilled, often 

 very unequal, larger 10 by 5 J in., subcordate, glabrous beneath except on the nerves ; 

 petiole attaining 4 in. Peduncles 1-4, f-l| in. ; cymes 5-8-fld., nearly glabrous; 

 bracts in., glabrous ; pedicels T ' g - in., mostly short. Calyx i in. aud upwards. 

 Corolla glabrous, white or very pale purple ; lobes |- in., round. Stamens, 2 fertile, 

 2 rudimentary. Ovary glabrous ; stigma peltate, oblique scarcely emarginate. The 

 corolla is that of Chirita, the capsule of Didymocarpus ; the stigma is nearly as in 

 Chirita Kurzii, from which it cau hardly be generically separated.

 hairy, peduncles 1-5-fld., calyx widely campanulate subentire, corolla 1 in.
