flower-heads clustered, forming dense terminal si:)ikes. Radical leaves 

 chiefly developed. 



Var. /8. EYOLUTIOR, Clark. 1. c. 83, panicles more or less branched, 

 larger or smaller ; radical leaves none or marcescent. 



Hab. Var. a. Tenasserim, Mergui (Wall.), a smaller form ; vai** ^. 

 Ava hills. 



A species apparently very variable as to inflorescence and habit, the 

 panicled form approaching J5. m«iY« and B. jlexuosa (if these be really 

 distinct from one another), while the subscapiferous forms look somewhat 

 like Gnajphalium. B. lacera, var. c. suhcapitata, Clark. {B. subcapitata, 

 DC. Prod. V. 439), is in my eyes the same as Clarke's var. y. Nilagirica of 

 this species. 



14. B. MACEOPHTLLA, DC. Prod. V. 446 ; Clark. Comp. Ind. 88. 

 {Conyza macrophylla, Bl. By dr. 896 ; B. procera^ DC. Prod. V. 445 ; Clark. 

 Comp. Ind. 86 ; B. semivestita, DC. Prod. V. 445). 



Yar. /3. peoceea {B.procera,J)G. Prod. V. 445; Clark. Comp, Ind. 86 ; 

 B. semivestita, DC. 1. c), flower-heads larger ; involucral bracts densely 

 pubescent ; pappus white. 



Hab. Var. f3. not unfrequent in the pine-forests of the Martaban hills, 

 at 3 — 5000 ft. elevation, descending into the damp hill-forests and becoming 

 more robust and large-leaved (B. macropliylla) ; also Ava, Khakyen hills 

 (J. Anderson). — Fl. March, April ; Fr. April.

 {Conyza halsamifera, L. sp. pi. 1208 ; Roxb. Fl. Ind. III. 427 ; B. densi-

 446 ; B. grandis, DC. Prod. V. 447 ? ; Inula ollonga var. a. DC. Prod. V. 

 4 quoad specim. e Taong-dong). 



Hab. Common and freely springing up in and often exclusively cover- 

 ing deserted toungyas, but also in savannahs, along river-banks, etc., all 

 over Burma, from Chittagong and Ava down to Tenasserim, up to 3,000 ft. 

 elevation.— Fl. Fr. HS. 



16. B. AEOMATicA, DC. Prod. V. 446 ; Clark. Comp. Ind. 88.

Looks like a grandular-pubescent from of B. sessilifolia, DC.

 Bydr. 897 ; B. tnyriocephala, DC. Prod. V. 445 ; B. squarrosa, Clark. 

 Comp. Ind. 87). 



Var. a. genuhsta, receptacle more or less densely pilose ; leaves beneath 

 and involucral bracts often more hairy. 



Var. y8. lanceolaeia {Conyza lanceolaria, Roxb. Fl. Ind. VII. 432 ; 

 B. longifolia, DC. Prod. V. 446 ; B. WallicUi, Clark. Comp. Ind. 87, excl. 

 syn. plur. ; Conyza nitida, Miq. Fl. Ind. Bat. II. 55. teste Clarke), recep-
