Hab. Not unfrequent in dry sandy pasture-land, in waste places 

 around and in villages, also river-banks of the Sittang and Irrawaddi delta 

 of Pegu. — Fl. Fr. April — June.

 Hab. Prome (Wall.). 



De CandoUe's B. spinellosa seems to be a spiny-toothed form of the 

 silvery silk-hairy form of B. hieracifolia ; Clarke's is near B. lacera (with 

 slender peduncles), or near B. harhata ?

 Clark. Comp. Ind. 74. {B. parvifolia, DC. Prod. V. 437 ? ; B. tricliophora, 

 DC. 1. c. 436 teste Clark. ; B. liymenopliylla^ DC. Prod. Y. 440 ; B. lacera 

 /3. liymenopliylla, Clark. Comp. Ind. 77). 



Hab. Common in all mixed forests, especially along choungs, freely 

 sprmging up in agrarian and waste lands, all over Burma, from Chittagong 

 and Ava down to Tenasserim ; also Andamans, here introduced and now 

 spreading. — Fl. Fr. DS. 



The colour of the florets and the much smaller size of the flower-heads 

 combined with a viscid pubescence ought to remove all difficulties in distin- 

 guishing this species from B. lacera, with which Bentham and Thwaites are 

 inclined to combine it. B. hymenophylla has pale blue or white florets and is 

 certainly nothing but a slendeik shade-form which I found in all transitional 

 states in company with B. Wight iana (not B. lacera, as Clarke states).
