 7-8 prominent beneath with glandular pits in the axils of some, other 

 nerves obscure. 



Ravines in the Santal Pargaiias, very rare ! 



Bark smooth, blaze lifiht yellow turning brown. N. puriud-en has not hitherto 

 been found north of the Circars and as flowers have not been collected from our 

 tree there must be a little doubt of its identity. The floral characters of X. pia-purea 

 <lra\vn from other specimens are: Heads' To" diam. terminal 1-3 together on 

 peduncles 2-3" long which are bracteate near the middle, bracteolcs conical 

 bristle-like, calyx silky, lobes purple, corolla glabrous. Fruit crowned with the 

 persistent base'of the calyx-loljes.
