This is quite near C. triyynum TILL, from which it is distinguishable only 

 in having much narrower petal*. It should letter be regarded as a variety 

 of the same species.

This is very near Steltaria mitans HEMSL. iu Journ. Linn. Soc. XXXIV. 

 p. 434, (Tibet Oriental : Tatsin-Lou) ; but differs from it by its larger and 

 broader leaves, and also in having rough velvety hairs all over the plant.
