As all the plants in the collection have been lately treated by 

 Sir Joseph D. Hooker in the Flora of British India v. 3 [1881], 

 I have given a reference for each species to that book instead of 

 copying ont all the synonymy. To shew the local geographic 

 distribution, I have added references to 



Miq. Fl. Ind. Bat. v. 2 [1856] 

 Vidal Pl. Vase. Filip. 

 Heinsley 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 Gompositae 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.
