Compositae (= Asteraceae, Lindley) 

 by C. B. Clarke — Kew. 



The Compositae sent me collected in Koh Chang by the Danish 

 Expedition to Siam (1899 — 1900) are 19; and are all known from 

 the Eastern part of British India, at elevations 0 — 400 metr. above 

 the sea. The plant enumerated below as Blumea subracemosa is no 

 real exception, as it might be almost, if not exactly, matched out of 

 the innumerable forms of Blumea lacera in the Indian collections. 



The low-level Compositae of Eastern British India consist of 

 wide-spread tropical plants that accompany cultivation, of a few 

 maritime plants, and of the universal Blumea, — the Eieracium 

 of Bengal. 



Sphaeromorphaea Busseliana is a rare plant, known to me only 

 as a weed in cultivated land. 



Wedelia scandens, Roxb., is known to me only as a strictly 

 maritime plant, in the Mangrove swamps and Soondreeboom. Its 

 distribution in Bombay is (fide D r Cooke) similar. It appears to 

 be very widely spread quite close to the sea in the tropics.
