Blake — A Revision of the Genus Viguiera 131 
monocephalous peduncles 6-35 cm. long, densely strigose below the 
heads; disk 7-10 mm. high, 1.2-1.8 cm. thick. Involuere 3(-4)- 
seriate, slightly or inconspicuously graduated, 9-11 mm. high, 
the phyllaries lanceolate to lance-oblong, acutish to acuminate, 
callous-mucronate, densely tuberculate-strigillose and tubercu- 
late-hispid-ciliate, herbaceous, not or only slightly indurated and 
ribbed at extreme base, appressed or slightly loose. Rays about 14, 
yellow, oblong, sparsely pubescent on back, 1.4-2.2 em. long, 
4-4 mm. wide; disk-corollas yellow, hirtellous chiefly below, 4.5 
mm. long (tube 0.5 mm.). Pales acutish to subacuminate, more 
or less strigillose above, often purplish-tinged in age, 7 mm. long. 
Achenes black, thickened, striate, strigillose at apex, 4.2 mm. long. 
Awns unequal, broadened and spinulose-ciliate below, 2.5 mm.

vicinity of Rio Janeiro and Ouro Preto, 1883-84, Glaziou 15077

(Herb. Imp. Brés. 881) proves to be identical with Viguiera anchu- 
saefolia, the present very distinct plant is left without a name, 
which it is a pleasure to supply by dedicating the species to Mr. 
J. G. Baker, F. R. S., whose treatment of the Compositae of Brazil 
in the Flora Brasiliensis is of the greatest value to all workers on 
the flora of that region. — T. 2. Fic. 17.
