2. B. quadrlseta, Hochst. in Hb. Schimp. Abyss, n. 2181 (1854). 

 An erect annual, 1-2 ft. high, scabrid-pilose especially on the upper 

 parts. Branches tetragonal. Leaves pinnately lobed, ovate in out- 

 line, 1^-4 in. long, including the petiole which ranges up to 1^ in. ; 

 lobes ovate or lanceolate, 1-2 by j— 1^ in., acute or acuminate, serrate, 

 sometimes incisely so. Capitula the size of B. pilosa^ and similarly 

 arranged. Involucral bracts densely pilose-pubescent, ^— f in. long, 

 linear, acute. Florets unknown. Achenes like those of B. pilosa, 

 ranging up to nearly 1 in., tipped by 4-3 setae. — B. abyssinica, Schultz

This species may prove to be merely a more hairy state of B. pilosa, as indeed it 

 has been considered by Schweinfurth. 



3. 8. bipinnata, Linn. Sp. Tl., ed. i., p. 832. An erect glabrous 

 or subglabrous annual of a few feet. Branches quadrangular. Leaves 

 mostly bipinnately lobed, ovate in outline, 1^-4 in. long or more ; 

 lobes ovate or oval or the terminal one lanceolate, incise-serrate, rang- 

 ing up to 2 by 1 J in. Capitula J-^ in. diameter in flower, elongated 

 and thicker upwards in fruit. Outer involucral bracts narrowly 

 linear, glabrous or cihate, \-\ in. long; inner broader, lanceolate, 

 glabrous, coloured, rather exceeding the outer. Ligule of the ray- 

 florets yellow or turning white according to Schultz. Achenes slender 

 elongated and gradually tapering towards the apex, glabrous, those of 

 the disk about ^— | in. long, tipped by 4-3 spreading retrorsely barbed 

 setae. — B. Kotschy% Schultz Bip. in Walp. Rep. vi. p. 168.
