As all the plants in the collection have been lately treated by 
Sir Joseph D. Hooker in the Flora of British India v. 3 [18814], 
I have given a reference for each species to that book instead of 
copying out all the synonymy. To shew the local geographic 
distribution, I have added references to 
Mig. Fl. Ind. Bat. v.2 [1856] 
Vidal Pl. Vasc. Filip. 
Hemsley Known Pl. of China 
(in Journ. Linn. Soc. v. 23 [1886—8}). 
The principal genus is Blumea, 6 ,species* or forms (besides 
Laggera). In dealing with these, I have only attempted to match 
the exemples of the Danish Expedition, stating where the match 
appears to me exact; and, if not exact, in what particular it does 
not quite agree. I have not made any attempt to revise the genus 
critically or to improve on Sir J.D. Hooker’s sorting and characters. 
Such a revision would occupy months, nor do I feel sure that the 
results would be an improvement. Similarly, as regards Wedelia 
scandens [Roxb. sub Verbesina], I have not sorted afresh the 
numerous examples of it in Kew, from Malaya, North Australia, 
Polynesia, mixed under numerous other names but nearly all of it 
included under the name Wedelia biflora by Bentham. 
The present 19 species may possibly include nearly all the 
indigenous Compositae of the Island of Koh Chang; but there is a 
considerable number of rice-field Compositae, any other of which 
might turn up in cultivation; or, if carried to Koh Chang, become 
plentiful there.
