 bricate, elongate, lanceolate or linear. Outer florets pistillate, pluri- 

 seriate ; inner florets few or solitary, tubular, hermaphrodite (or

1, A. senegralensis, Benth, in Hook. Ic. Fl. 1144. Glabrous 

 erect annual herb of 1-1^ ft. more or less, branched above, each 

 branch terminating in a capitulum ; stem and branches terete with 

 raised decurrent lines or very narrowly alate from the leaf-bases. 

 Leaves linear, remotely pectin ate -pinnatipartite, varying to 2 in. in 

 length, rachis and lobes \ line broad or narrower. Capitula terminal, 

 -|-1 in. diam., often corymbose, surrounded by the upper leaves which 

 Jose their lateral lobes and pass gradually into the involucre. Involu- 

 cral scales linear-lanceolate, long-acuminate, 1-nerved, outer tomentose 

 at least below, inner scales lanceolate-subulate hyaline. Pistillate 

 florets very numerous; corolla easily separating, filiform-tubular, mouth 

 minutely unequally (4-) dentate. Style-branches slender, elongate.
