Shrubs or perennial herbs. Leaves opposite, petioled, entire or obscurely 
- toothed, lineolate by raphides. Spikes linear with distant flowers, or dense 
or capitate; bracts usually large; bracteoles linear-lanceolate, hardly so 
long as the calyx. Corolla-tube linear, long, widened only near the top or 
m a few species from the middle; lobes obovate, twisted to the left in 
bud, horizontal in flower, blue, rarely rose, veined. Stamens 2, glabrous; 
anthers narrowly oblong, 2-celled, muticous, exserted or subincluded. Ovary 
glabrous, 4-ovuled; style long, sparingly hairy, stigma simple linear. 
apsule clavate, base solid cylindric. Seeds normally 4, compressed, discoid, 
densely finely elastically hairy when wetted—Species 17, Indian and

. This genus, in the long corolla and 2 stamens with muticous anthers, greatly 
Simulates Eranthemum ; the species are in general easily distinguished by the bracts 
much exceeding the calyx; in D. microstachyus & concanensis, however, the bracts 
are small, and they can only be recognized by their twisted corolla-lobes. 
* Corolla lower half cylindric, upper half ventricose or funnel-shaped.
