546 Lxxi. COMPOSITE. [Betris 



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 F. ahyssinica rather than with. 

 F. Schimperi. 



Var. ? anthemidodes. 



A hispid, scabrid, annual herb ; the central stem erect with 

 numerous ascending branches spreading from the base in different 

 directions, J to 2 ft. high, with the habit of an Anthemis, but 

 scarcely aromatic ; branches rather slender and leafy, pallid, 

 simple below; leaves alternate or the lowest ones opposite, 

 subhnear, obtuse, sessile, i to f in. long, yellowish-green on 

 both faces, densely hispid with grey rather short stiff hairs 

 arising from a bulbous base entire; capitula sub-hemispherical, 

 f to i 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 ; setae setulose.

2. D. mossamedensis Hiem, sp. n. 



A pallid undershrub ; older branches terete, glabrate, ashy- 

 purplish ; branchlets spreading ; twigs fasciculate ; hispid- 

 pubescent, leafy , leaves alternate or approximated, linear, obtuse 

 or apiculate at the apex, rather narrowed towards the rather 

 broad sessile base, scabrid-hispid with stiff short whitish hairs, 

 pale yellowish-green, grey-canescent, i to -J in. long, entire, flat 

 or concave ; the hairs seated on a minute bulbous (glandular ?) 

 base; capitula broadly campanulate or sub-hemispherical, 15- to 

 20-flowered, radiate, heterogamous, ^ to -|- in. in diameter (in- 

 cluding the ligules), numerous, solitary, terminating the shortly 

 (1^ to f 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 -^ in. long, the inner 

 ones i in. long ; ligulate florets female, uniseriate, ^ to ^\ in. 

 long, the ligule oblong, 2 •■ or 3-toothed at the apex ; disk-florets 

 hermaphrodite, pluriseriate, i in. long (exclusive of the exserted 

 style-branches), the corolla tiibular, shortly 5-lobed ; anthers 

 shortly produced at the apex, obtuse not sagittate at the base ; 

 style-branches rather short, lanceolate ; young achenes minutely
