bupleuroides in the broader, more or less obovate, bracts. Nees founded his species 

 on the common Assam and E. Bengal plant, and the original ticket on his type 

 specimen is marked Assam. Bentham, however (in Fl. Hongk. 266), says this was au 

 error, and that this type specimen came from the Calcutta Botanic Garden ; but it is 

 not known how Bentham discovered this. Nees, however, is in error in citing Rox- 

 burgh's Justicia chinensis, for Roxburgh's Ic. Ined. proves this to have been the true 

 plant, long cultivated at Calcutta.

 alt. 1-6000 ft., abundant in the north, becoming rare in the Malabar Ghauts ; in the 

 Himalaya from Kashmir to Upper Assam and the Chittagong Hills ; Mt. Aboo, Stocks; 

 Central India. Distrib. Affghanistan. A large very uniform series, varying only 

 slightly in the pubescence of the bracts. In the extreme forms the bracts are by 

 T l g in., glistening ciliate, and in some 'of Beddome's Malabar specimens they are almost 

 subulate. Though the bracts are often broader than in these, the plant as a whole is 

 tolerably well separable from D. Roxburghiana,.

 minal, often panicled by the reduction of the floral leaves ; bracts 1-4

 linear-lanceolate, shorter than the bracts. Calyx deeply 5-lobed ; segments 

 equal, linear-lanceolate. Corolla rose or purple ; tube slender, limb deeply 

 2-lipped, upper lip subentire, lower very shortly 3-lobed. Stamens 2;

 4-seeded, more or less dusky pubescent. Seeds ovoid, compressed, glabrous, 

 minutely glandular-papillose, scarcely verrucose. Species 15, from Tropical
