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 Blumew 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 Blwmea, — the Hieraciwn 
of Bengal. 
Sphaeromorphaea Russelianu 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* Cooke) similar. It appears to 
be very widely spread quite close to the sea in the tropics.
