1. A. Cotula, Linn. Sp. Pl. ed. i. p. 894, A somewhat leafy but 
inconspicuously hairy herb, usually decumbent, branched, ranging UP 
to 21 ft. high or more. Leaves tripinnatisect, ovate, 1-3 in. long; 
segments narrowly linear, acute or with a terminal callus. Capitula

Involucral bracts oblong, hairy, with a green midrib and usually dar 
brown and crisped margin. Ligules of the usually neuter ray -florets

These forms differ from the type by dark margins of the involucral bracts an ps 
of the scales of the receptacle. A. tigrensis is in general smaller, more hairy, and has 
the leaf-lobes shorter than in A, abyssinica.
