432 LXXIII. COMPOSITE (OLIVER AND HIERN). [ Echinops. 
4, B. macrochetus, Fresen. in Mus. Senckenb. iii. p. 69. Erect, 
branched, 3-5 ft. high. Branches glandular-pubescent above, terete, 
striate. Leaves sessile, semi-amplexicaul, oblanceolate or elliptical, 
acute at both ends, glandular-puberulous above, white-tomentose 
beneath, ranging up to 8 in. or more, deeply pinnatifid in the upper 
part, pinnatipartite in the lower part, segments ovate or lanceolate, 
pinnately incise or dentate, the teeth and apex terminating in a long 
spinous point. Heads about 2 in. long, comparatively few, crowded in. 
clusters of about 1} in. diameter. Outer setaceous bracts very numer- 
ous, silky, some about 4 in. long, nearly white. Inner involucral 
bracts spathulate or sublinear, apiculate, about 18; the innermost con- 
nate into a tube more than half way up. Achenes densely setulose, 
obovoid. Pappus consisting of equal adjacent setaceous ciliate scales 
as long as the uppermost hairs on the achenes, connate at base into a 
shallow cup.—A. Rich. Fl. Abyss. i. p. 451.

5. B. hispidus, Fresen. in Mus. Senckenb. iii. p. 68. Stem 
branched, white-tomentose, densely hispid as well as the nerves of the 
leaves with hairs } in. long. Leaves pinnatipartite, strigose-scabrid 
above, white-tomentose beneath, segments pinnatifid or unequally 
trifid from the base only, lobes linear-lanceolate revolute at the mar- 
gin, terminating in a long pungent spine. Heads 1} in. long in clus- 
ters of 3in. diameter. Outer setaceous bracts reaching more than 
half way up the involucre. Inner involucral bracts glabrous on the 
back, setose-ciliate, the innermost connate half way. Pappus of 
unequal ciliate setaceous scales connate at the base—A. Rich. Fi. 
Abyss. i. p. 452. 
Mile Land. Abyssinia, Riippell. 
The description is taken from Fresenius. 
6. B. longisetus, A. Rich. Fl. Abyss. i. p. 450. Stem erect 
6-8 ft. high, puberulous and ribbed above. Upper leaves narrowly 
elliptical or oblanceolate, pinnatipartite, glabrate above, shortly white- 
tomentose below, about 9 by 3 in., lobes from a broad base terminating 
in long stout spinous points, the lower lobes smaller and less approx! 
mated. Heads about 14 in. long (in fruit), very numerous, crowde 
into a globose head of 4 in. diameter. Outer setaceous bracts long, 
some nearly reaching the top of the head. Inner involucral bracts 
about 20, fasciculate-spinous at the tip except the 5 innermost ones 
which are connate below. Achenes obovoid, pilose. Pappus of ap- 
proximated narrow ciliate scales rather longer than the hairs on the 
achenes, connate below.

7. B. giganteus, A. Rich. Fl. Abyss. i. p. 449. Stem erect, 
branched, 6-16 ft. high, branches more or less cottony above, striate 
or ribbed. Upper leaves obovate, deeply pinnatifid, sparingly strigose- 
hispid above, whitish-tomentose beneath, about 12 by 6 in, sessile OT
