Capitula heterogamons radiate, ray-florets 1 -seriate, ligalate, con- 

 spicuous, white or yellow, $ or neuter. Involucre hemispherical; 

 bracts pluriseriate closely imbricate with scarious margins, outer suc- 

 cessively shorter. Receptacle paleaceous convex or conical. Anther- 

 base entire. Style-branches truncate, penicillate. Achenes oblong, 

 apex obtuse ; pappus or coroniform or unilateral. — Herbs with alter- 

 nate toothed or pinnatisect leaves often with narrow segments and 

 terminal pedunculate often rather large capitula. 

 A considerable genus, chiefly European and Mediterranean. 



Leaves tri pinnatisect. Plant ranging up to 2^ ft 1. A, Cottda. 



Leaves bipinnatisect. Plant dwarf, 1-2 in 2. A. pygmaa. 



1. A. Cotiila, Linn. Sjp. PI. ed. i. p. 894. A somewhat leafy but 

 inconspicuously hairy herb, usually decumbent, branched, ranging up 

 to 2^ ft. high or more. Leaves tripinnatisect, ovate, 1-3 in. long ; 

 segments narrowly linear, acute or with a terminal callus. Capitula 

 ^— ^ in. diameter exclusive of the rays, terminal, solitary, pedunculate. 

 Invoiucral bracts oblong, hairy, with a green midrib and usually dark 

 brown and crisped margin. Ligules of the usually neuter ray-florets 

 white, ^-^ in. long. Scales of the receptacle narrowly lanceolate, 

 nearly equalling the florets, tips setaceous brown. — A. ahyssinica/J.

These forms differ from the type by dark margins of the invoiucral bracts and tips 

 of the scales of the receptacle. A. tigrensis is in general smaller, more hairy, and has 

 the leaf-lobes shorter than in A, ahyssinica.

 220 ; Schweinf. Fl. ^thiop. 142, n. 726 {sine descriptione). A dwarf gla- 

 brous perennial herb, 1-2 in. high. Rootstock thick, branched. Leaves 

 narrowly oblanceolate, pinnatipartite, petiolate, ^If in. long ; pinnaB 

 subpalmatisect, | in. or less, the lower ones remote ; pinnules linear. 

 Capitula hemispherical, inclusive of the rays ^-1 in. diameter, solitary, 

 terminal, shortly pedunculate. Invoiucral bracts oblong, "obtuse, 

 thinly pubescent ; margins dark brown. Scales of the receptacle nar- 

 rowly linear, acute, nearly equalling the florets ; tip brown. Ligule of 

 the neuter florets oblong, obtuse, ^ in. long.
