This interesting plant was discovered in the north-west 

 corner of Sikkim near the Tibet frontier at an altitude of 

 over 15,000 feet, and very near the limit of vegetation for 

 the area. Its habitat is generally loose, shingly screes. 

 One of the dominant genera of the area is Saussurea, and 

 Cavea has much in common as regards habit with several 

 of the Himalayan species of that genus. Its position in or 

 near the Pluchineae is, in our present knowledge, where we 

 find we must put it on the characters presented, but the 

 authors realise that such a position may not be its natural 

 one. It has been with hesitation that this extreme alpine 

 has been associated with Fluchea, Blumea, and Laggera. 

 If the characters permitted, its placing near Saussurea or 

 Berardia would have been more satisfactory from the 

 fades of the plant. The generic name attached to the 

 plant is in honour of Mr. George Cave, Curator of the 

 Lloyd Botanic Garden at Darjeeling, an indefatigable 

 traveller and collector over the whole of Sikkim, and one 

 to whom the discovery of many new plants is due. 



The plant was first described by Mr. J. R. Drummond 

 from material collected by Sir F. Younghusband while
