65. V. TENUIFOLIA Gardn. Stem slender, subflexuous, rather 
densely strigose, monocephalous. Leaves alternate, linear, entire 
or very remotely toothed, long-acuminate, sessile, strigose both

Rays linear, 14-17.5 mm. long, 2-2.5 mm. wide; disk-corollas 
sparsely hirtellous, 4.8 mm. long (tube 0.8 mm.), the throat funnel-

— BRAZIL: Minas Gerazs: Sierra de Curral del Rey, Sept. 
1840, Gardner 4927 bis (TyPE coL.: B. M., tracing G.). — In the 
original description the length of the leaves is given as “ 4-514 
lin.,” an obvious lapsus for “‘ 4-514 poll.” This species is omitted 
from the Flora Brasiliensis. 
66. V. Kunrurana Gardn. Erect, 2.3-10 dm. high, the stems 
solitary or few, slender, rather few-leaved, sparsely pilose below, 
strigose-pilose above, bearing 1—4 long-peduncled heads. Leaves 
linear, alternate (only the lowest pair opposite, very much reduced 
and almost scalelike), attenuate, sessile, entire, slightly revolute, 
3-nerved, tuberculate-strigillose above, scarcely paler, strigillose, 
and gland-dotted beneath, 5.3-11 em. long, 1.5-3.5 mm. wide. 
Peduneles axillary and terminal, strigillose, mostly 1.1-3.1 dm. 
long; heads 3.2-5.6 em. wide; disk 6—(fruit)10 mm. high, 11- 
(fruit)15 mm. wide. Involucre 2-seriate, 7-9 mm. high, the phyl-

strigillose, herbaceous, at base slightly thickened and ribbed. 
Rays 16-24, oblong to oblong-lanceolate, 1.2-2.5 em. long, 3-7 mm.
