44 PENTANDRIA DIGYNIA. Aschpias. 



made, do not enable me to say positively in what pro- 

 portion they yield their colour; but it was of an excellent 

 quality, and as the plant grows very readily from layers, 

 slips, or cuttings, I think it very well worthy of being cul- 

 tivated ; particularly as it is permanent, like the Nerium, 

 so that a plantation once formed, well continue for a num- 

 ber of years ; and if we are allowed to draw a compari- 

 son between the leaves of this plant, and those of Neri- 

 um tinctorium, the quantity of colour they may yield will 

 be in a larger proportion than from the common Indigo 

 plant. 



Since writing the above I have learned that this plant 

 is a native of Cooch-bahar and I had some of the plants 

 sent me from thence, also from Pegu, from whence I have 

 likewise received plants. 



Some more experiments I have made with the leaves, 

 comfirm what is above related, not only respecting the 

 quality of the Indigo, but also that the proportion is con- 

 siderably greater than is obtained from Indigofera tinc^ 

 toria. I have therefore warmly recommended an exten- 

 sive cultivation thereof.

This is also a perennial, twining species, a native of 

 hedges, &c. flowering time the wet, and cold season ; it 

 abounds with milky juice. Tender parts hairy. The 

 smell offensive. Leaves opposite, petioled, broad-
