These differ from the type of the species by the capitula being not 
always solitary at the extremities of the stems and branches, but 
often arranged in lax terminal bracteate panicles ; in other respects 
they agree better with the form /. abyssinica rather than with 
EF’. Schimperi. 
Var. ? anthemidodes. 
A hispid, scabrid, annual herb; the central stem erect with 
numerous ascending branches spreading from the base in different 
directions, + to 2 ft. high, with the habit of an Anthemis, but 
2 
scarcely aromatic; branches rather slender and leafy, pallid, 
simple below; leaves alternate or the lowest ones opposite, 
sublinear, obtuse, sessile, + to # in. long, yellowish-green on 
both faces, densely hispid with grey rather short stiff hairs 
arising from a bulbous base entire; capitula sub-hemispherical, 
2 to 4+ in. in diameter, many-flowered, pedunculate, terminating 
> 
the branches, forming altogether a sub-hemispherical leafy 
panicle as wide as the whole plant; involucral scales pauci- 
seriate, sublinear, acute, hispid-pilose on the back, with whitish 
scarious margin, the outer ones rather shorter than the inner ; 
florets whitish ; ligule of the ray-florets linear-oblong, spreading ; 
achenes flattened, with a thickened border, somewhat setulose, 
obovate ; pappus arising from a cartilaginous ring smaller than 
the achene in width, white, setose, uniseriate ; sete setulose.

cluding the ligules), numerous, solitary, terminating the shortly 
(4 to 2 in.) peduncular branches, erect ; involucral scales pauci- 
seriate, linear or lanceolate, acute, ciliate and hispid or minutely 
papillose on the back, the outer ones about 54, in. long, the inner 
ones + in. long; ligulate florets female, uniseriate, } to 9; in.
