This is a well-marked species with its long pointed leaves; there may be several 

 forms according to their more or less compound serration. 1 have not seen sufficient 

 material to make it possible to say whether or not the western forms are different 

 from those from the eastern parts of the Himalaya. This species certainly is closely 

 related to the following.

This species is certainly very closely related to C. viminea Wallich, and may per- 

 haps be better treated as a geographical variety. For the main differences see the 

 key, p. 432. I have not seen any male flowers of C. viminea. Those of C. Londoni- 

 ana may be described as follows: 



Amenta mascula circiter 6 cm. longa; bracteae ovatae v. ovato-lanceolatae, 

 cuspidato-acuminatae, brunneae sed apice purpurascentes, faciebus glabrae, mar- 

 gine plus minusve breviter cihatae, apicem versus glabriores, circiter 6-7 mm. 

 longae et 2.5-3.5 mm. latae; stamina circiter 10, toro piloso inserta thecis oblongo- 

 ellipticis separatis apice rubro-brunneis et hirsutis, filamento communi iis fere 

 aequilongo.
