Blake — A Revision of the Genus Viguiera 139 
tuberculate-hispid-pilose with spreading hairs, their whitish bases 
persistent. Leaves alternate, sometimes opposite on the flowering 
branches, ovate, subacuminate, the mucronate apex generally 
decurved, rounded to rounded-cuneate at base, entire or obso- 
letely serrulate, scarcely revolute, 3-nerved, above dark green, 
densely lepidote-strigillose, beneath decidedly paler, somewhat 
densely hispid-pilose with rather soft hairs and more or less 
venose-reticulated, 4.5-5.5 em. long, 1.5-2.2 em. wide; petioles 
tuberculate-hispid-pilose, about 1.5 mm. long. Peduncles 4.7— 
14.5 em. long, naked or bracteate, bearing one or rarely two heads; 
heads about 5, 3.7 cm. wide; disk 11 mm. high, 14-16 mm. thick. 
Involucre 3-4-seriate, distinctly but slightly graduated, 7 mm. 
high, the phyllaries lanceolate to lance-oblong (the inner broader 
and longer), acute to subacuminate, callose-mucronulate, slightly 
spreading, blackish-green, slightly indurated, ribbed, and glabrate 
at least in age near base, elsewhere densely strigose-hispid and 
-tuberculate except often at apex. Rays 16-18, oval, subentire to 
tridenticulate, 14 mm. long; disk-corollas somewhat strigillose, 
4.2 mm. long (tube 1 mm.). Pales stiff, acute, carinate, sparsely 
strigillose or almost glabrous, 7 mm. long. Achenes (immature) 
rather sparsely strigose-pilose. Awns slender, very unequal, 1.2- 
2.2 mm. long; squamellae fimbriate, united at base or nearly to 
apex, 0.7 mm. long. — Hochr.! Bull. N. Y. Bot. Gard. vi. 294

89. V. Sodiroi (Hieron.), comb. nov. Erect branched herbaceous 
perennial; root with a cluster of thickened fleshy rootlets; stem 
pilose, at length subglabrate, the somewhat thickened bases of the 
hairs persistent. Lower leaves opposite (about 6 pairs), the others 
alternate, ovate, acute, cuneate to rounded at base, dentate- 
serrate above the middle with about 10 pairs of fine subremote 
teeth, the uppermost entire, greenish and pilose above, beneath 
densely canescent-tomentose-pilose, 5.2-9.5 cm. long, 2-4.2 em. 
wide; petioles densely pilose, 5-11 mm. long. Heads about 5, 
terminal and on axillary leafy branchlets or peduncles, 7.5 cm. 
wide; disk 2-2.6 cm. high, 2.8-3.3 em. thick. Involucre about 
3-seriate, graduated, 1.6 cm. high, the phyllaries oblong, mucro- 
nate, densely tomentose-pilose except at apex and on midline of 
back, scarcely thickened at base. Rays about 32, oblong, 2.6-
