 locality. 



It is distinguished, as far as the sterile plant is concerned, by the 

 main stem being densely beset with very large compound prickles 

 which have two to six cusps. The smaller stems have simple prickles 

 fewer and smaller than those on the main stems, but even the prickles on 

 these are larger than the prickles usually met with in corresponding 

 situations on D. hirmanica. Tlie petioles are prickly as in the Burmese 

 plant and have the same basal stipular thorns ; but the leaves them- 

 selves are rather differently sliaped, being ovate-cordate, 20 cm. long by 

 11 cm. broad, and having no thorns on the veins : the younger leaves 

 have hairs beneath towards the base. The plant, which is probably an 

 undescribed species, deserves to be looked for.
