110. V. aTacAMENSIs Phil. Herbaceous (?), the branches erect- 
ish; stem rather sparsely tuberculate-strigillose, the hair-bases 
persistent. Leaves alternate, linear, acute to subacuminate at 
each end, mucronate, 1-nerved, feather-veined, above green, 
densely tuberculate-strigillose, beneath somewhat paler, densely 
gland-dotted and evenly tuberculate-strigillose (the hairs longer 
along the costa), often with short leafy branches in their axils, 
slightly revolute, 3.5-7.5 em. long, 2-4 mm. wide; petioles 1-2 mm. 
long. Heads rather numerous, narrowly cymose-panicled, 1.4-2 cm. 
wide, on striate tuberculate-strigillose peduncles about 4 cm. long; 
disk 9-(fruit)12 mm. high, 9—(fruit)15 mm. thick, campanulate. 
Involucre 3-seriate, graduated, 6-6.5 mm. high, the phyllaries 
lanceolate or long-oblong, acute to subacuminate, callous-mucro- 
nate, below strongly indurated, pale, and somewhat ribbed, there 
nearly glabrous except for the tuberculate-strigillose margin, with 
much shorter densely tuberculate-strigillose reflexed or spreading 
herbaceous apex. Rays 10-12, 7-9.5 mm. long, 2.5 mm. wide; 
disk-corollas strigillose chiefly below and on the teeth, 5.5 mm. 
long (tube 1 mm.). Pales mucronulate, scarious, few-ribbed, 
hirtellous on keel, 7.5 mm. long. Achenes (submature) rather 
sparsely strigose-pilose, 4.5 mm. long. Awns 3.84.5 mm. long; 
squamellae about 4, oblong-lanceolate, acuminate, united at base, 
lacerate, 2mm. long. — Viguieria ? atacamensis Phil. ! Anal. Mus.
