Blake — A Revision of the Genus Viguiera 127 
baceous, below slightly indurate-ribbed, tuberculate-strigillose, 
more or less hispidulous-ciliolate, the outer 1.8-2.8 mm. broad. 
Rays about 16, narrow-oblong, sometimes styliferous but sterile, 
2.2-4.2 em. long, 5.5-10 mm. wide; disk-corollas somewhat puber- 
ulous below, 5.5 mm. long (tube 1.2-1.5 mm.). ales acuminate, 
tuberculate, 9-13.5 mm. long. Achenes thickened and angular, 
subglabrous or sparsely puberulous above, 5-7.5 mm. long, 
1.8 mm. wide. Awns somewhat paleaceous, 1.5 mm. long; squa- 
mellae about 10, distinct, unequal, lacerate-fimbriate, 0.6 mm. long. 
— This somewhat variable plant may be divided into two forms 
on the basis of leaf-characters.
