upper ones smaller and narrower bnfe' all petiolafce. Flower-heads about 4 lines 

 long, all pedunculate or perhaps as in some Indian specimens a few of the upper 

 ones almost sessile, forming a large pyramidal panicle. 



Hab.: Endeavour Eiver, BanlcK and Solander ; Broadsound and Shoalwater Bay, i?. Brown ; 

 Port MoUe, M'Gillivray. 



The species is widely spread over E. India and the Archipelago, extending to S. China. — 

 Benth. 



Var. minor. Not exceeding IJft. in height. Leaves and flower-heads smaller. — Port Molle, 

 M'GitUvray ; llockhampton, Thozet. 



2. B. amplectens (leaves clasping the stem), DC. Prod. v. 438 ; Be.nth. Fl. 

 Aiistr. iii. 525. An annual with erect or ascending stems, usually under 1ft. high, 

 more or less covered with a glandular-viscid pubescence. Radical leaves obovate 

 and petiolate, the stem leaves all sessile and stem-clasping, from ovate to lanceo- 

 late, acutely-toothed and usually small. Flower-heads all pediinculate, not 

 numerous, in a loose panicle, very divaricate in Indian specimens, less so in the 

 Australian ones. Involucres nearly 3 lines long. Style-branches of the disk- 

 florets long and slender. 



Hab.: Keppel Bay, Thozet ; Connor Eiver, Bowman. 

 The species is common in E. India. 



3. B. integrifolia (leaves usually entire), DC Prod. v. 433 ; Benth. Fl. 

 Austr. iii. 525. A rather slender annual, erect or branching from the base, rarely 

 above 1ft. high, pubescent or hirsute, and perhaps sometimes viscid, the young 

 shoots occasionally silky-woolly. Leaves oblong-lanceolate or rarely the Ipwer 

 ones almost obovate, acute and bordered by distinct aeate teeth, rather rigid and 

 often scabrous, the lower ones 1 to 3in. long, the upper ones smaller, narrowed 

 towards the base or broad and stem-clasping at the base. Flower-heads not 

 clustered, the peduncles at first short but generally long and slender when the 

 flowers are fully out. Involucres 2 to 3 lines long. 



Hab.: Islands of the Gulf of Carpentaria. 



4. B> diffusa (plant diffuse), B. Br. Herb.; Benth. Fl. Auntr. iii. 525. A 

 small slender and diffuse annual, slightly viscid, with a very little wool at the 

 base of the stems, rarely exceeding 6in. including the peduncles. Leaves chiefly 

 radical and rosulate, petiolate, obovate-oblong, i to 1 or rarely 2in. long ; those 

 on the stem few, small, ovate, stem-clasping. Peduncles long and very slender. 

 Flower-heads small, glabrous or slightly pubescent. 



Hab.: Islands of the Gulf of Carpentaria, B. Brown ; Thursday Island. 



5. B. hieracifolia (Hieraoium-leaved), DC. Prod. v. 442 ; Benth. Fl. Austr. 

 iii. 526. An erect stiff almost simple annual, 1 to 2ft. high, more or less tomen- 

 toge or densely villous, but not viscid. Leaves oblong, irregularly and sharply 

 toothed, the lowest nearly obovate, 2 to Sin. long, and petiolate, the others sessile 

 or nearly so but narrowed at the base, the uppermost almost lanceolate. Flower- 

 heads about 4 lines long, mostly sessile and clustered, the lower clusters distant, 

 the upper ones forming a terminal leafy spike, or more rarely branching into an 

 oblong terminal panicle. Involucres always tonientose, the bracts linear, acute 

 and soft as in the rest of the genus, but rather broader than in the following 2 

 species. — Wight, Ic. t. 1099 (representing a dwarf form). 



Hab.: Broadsound, R. Brown; Keppel Bay, Thozet; Moreton Bay, Leichhardt ; Thursday 

 Island. 



The species is one of the common ones in tropical Asia from Ceyloft and the Peninsula to the 

 Archipelago, and northwards to S. China and Formosa. E. Brown's and F. v. Mueller's 

 specimens belong to the very villous var. holqsericea, Benth. Fl. Hongk. 178, or B, holosericea, 

 DC. Prod. V. 442. Leiohhardt's and Thozet's are less villous, the leaves of the former nearly 

 glabrous and on longer petiole^,— .PwtA,
