Indigenous in India; widely cultivated and occasionally naturalised elsewhere. 

 There is a long- and a short-styled form in India, the pistil measuring 5-6.] lin. and 

 2i-3i lin. respectively. The first has the anthers in the middle of trie con)lla-ttibe, 

 the other at | from the base. Both occur in cultivation in a double-flowered fonn. 

 The wild simple short-styled form seems, however, to be confined to tlie northern 

 parts of India. Nerium dioaricatum, Linn. Sp. PI. i. 201), based on Hernumn's 

 Apocynum zeylanicum (Parad. Batav. 40) and supjHwed to be identical with Nerium
