Blake — A Revision of the Genus Viguiera 141 
tuberculate-hispid-pilose with rather short slightly harsh incurved 
hairs, their bases persistent, beneath paler, in youth subcanescent 
with rather dense loose curly hairs intermixed along the veins 
with longer straighter ones, less pubescent in age, gland-dotted, 
3-nerved slightly above the base, 8-10.5 em. long, 1.8-3.5 cm. 
wide; petioles densely tuberculate-hispid-pilose, 3-6 mm. long. 
Heads in 1’s-3’s at ends of branches and on axillary peduncles, 
5-6 cm. wide, on peduncles 8 em. long or less and pubescent like 
the stem; disk 9-12 mm. high, 15-18 mm. thick. Involucre 3- 
seriate, graduated, 7-10 mm. high; phyllaries rather densely 
and more or less canescently pilose with appressed soft hairs 
(searcely or not at all enlarged at base), with oblong or oblong- 
obovate body, indurated, pale, and about 4-vittate, sometimes 
subglabrate below, and rather abruptly narrowed spreading or 
reflexed shorter lanceolate herbaceous apex (distinctly green but 
shortly appressed-pilose within). Rays about 12, linear-oblong, 
2.5 em. long, 6 mm. wide; disk-corollas puberulous below and on 
the teeth, 5 mm. long (tube 1 mm.). Pales puberulous at the 
shortly acute apex, otherwise glabrous, 7 mm. long. Achenes 
(submature) ciliate, otherwise practically glabrous, slightly 
thickened, 2.5 mm. long. Awns ampliated below, 2 mm. long, 
somewhat deciduous; squamellae subequal, subquadrate, fimbri- 
ate, 0.5 mm. long, persistent. — Britton! Bull. Torr. Club xix.

species like the two following approaches Helianthus in its some- 
what deciduous pappus, but from the presence and greater or less 
persistence of the squamellae is better referred to Viguiera. 
92. V. pazensis Rusby. Erect, herbaceous, branched, the stem 
and branches terminated by 2-4 pedunculate heads. Stem stout, 
tuberculate-strigillose or -strigose-hispid. Leaves alternate, lanceo-
