Information
Large, subscandent; branches sharply quadrangular. Leaves up to 8 by 3 1/4 in., spathulate-elliptic, hardly petioled, thin in texture, very sparsely hairy, cystoliths obscure; margin entire, obscurely waved. Inflorescence in viscid-hairy axillary panicles 3–6 in. long, but (by the falling of the floral leaves) apparently a terminal panicle 14 by 8 in.; bract 1/3 in. long, oblong; bracteoles similar, rather smaller. Calyx 1/2 in. long, divided 1/3– 1/2 the way down, more or less viscid-hairy; teeth narrow-lanceolate. Corolla 2/3 in. long (linear-cylindric portion 1/3 in. long), purple with brown transverse marks and strong deflexed simple hairs in the throat. Stamens, anthers, pollen, pistil, stigmas, and ovules as of D. kilimandscharicum. Capsule (and seeds) as of D. kilimandscharicum, but a little larger, 1/4 in. long.

Notes
This fine plant has all the appearance of one of the large rambling Indian Strobilanthes: except by the number of ovules it might be placed in that genus. Klotzsch has misled everybody by printing that the cells of the ovary are vieleiig (many-ovuled) instead of viereiig (4-ovuled).
