£. fistulosa, Roxb. 1. c), spikes more or less panicled ; receptacle tawny 

 velvety, the velvet sometimes intermixed with a few white soft hairs. 



Var. ^. RACEMOSA, Clark. 1. c. {B. racemosa, DC. Prod. V. 442), spikes 

 almost simple or little branched ; receptacles yellowish velvety. 



Var. y. glomerata, Clark. 1. c. {B. glomerata, DC. Prod. V. 443 

 Gonyza Burmeana. Miq. Fl. Ind. Bat. II. 44), sj^ikes more or less panicled j 

 receptacles velvety, the velvet intermixed with copious soft white hairs. 



Var. 8. HOLosEEiCEA, Clark. 1. c. {B. Tiolosericea, DC. Prod. V. 442), 

 more simple, thinly silky pilose, the spikes usually simple, rarely with a 

 few additional basal ones, long-silky-pilose ; receptacle shortly white pilose. 



Hab. Var. a. /3, and -y. equally common in all deciduous forests, es- 

 pecially the drier ones, on ruined pagodas and walls, in rubbishy places, 

 along river-banks, etc. ; and as a troublesome weed in deserted toungyas, 

 especially in those of the hills, all over Burma, from Chittagong and Ava down 

 to Tenasserim, up to 4,000 ft. elevation ; var. 8. is a laterite form pretty 

 frequent in the eng-and hill-eng forests of Martaban and Tenasserim, but 

 rather rare in the upper dry forests of the Prome Yomah, up to 3,000 

 ft. elevation.— PL Fr. C. and HS. 



The above varieties are, with the exception of 8, hardly worth keeping 

 up. Bentham (Fl. Hongk. and Fl. Austr. IV. 526) refers B. liolosericea 

 DC. to his B. hieracifolia, but a scrap of Wallich's authentic specimens 

 shews small sessile heads, indeed represents the upper part of the form cor- 

 rectly referred by Mr. Clarke to the above species. A Hongkong specimen 

 named B. holosericea by Dr. Hance — I suppose on Bentham' s authority — 

 seems to belong either to the silvery-silky form of B. lacera or to B. 

 hieracifolia (the flower-heads are too young). 



12. B. EARBATA, DC. Prod. V. 484 ; Clark. Comp. Ind. 73. 



Var. a. genuiista, leaves broader or narrower ; flower-heads on 

 slender or short peduncles in a diffuse usually long-jjilose panicle, or the 

 panicle reduced and raceme-like but laxly contracted. 



Var. y8. sericans, leaves more elongate-cuneate to almost linear, ap- 

 pressed silvery pubescent like in B. lacera ; flower-heads larger, almost 

 sessile or thickly peduncled, clustered in the axils of the leaves and gra- 

 dually passing into terminal dense spikes. 



Hab. Var. a. Upper Tenasserim, Moulmein (Falconer) ; var. /?. in 

 the upper mixed forests, rare along the Zamayee choung in the Pegu Yomah, 

 but more frequent in those along the Toukyeghat river in Martaban 

 east of Tounghoo. — Fl. Febr., March ; Fr. March, April.
