Blake — A Revision of the Genus Viguiera 185 
densely hispidulous, 1 em. long, squarrose, the inner subglabrate 
above and scarious-membranous. Rays 11 mm. long; disk- 
corollas puberulent below and on the teeth, 4.8 mm. long. Pales 
acuminate, subcarinate, glabrous, 7 mm. long. Achenes more or 
less compressed, appressed-pubescent, 3.5 mm. long. Awns per- 
sistent, 4 mm. long; squamellae small, very much shorter. — 
Helianthus cornifolius HBK. ! Nov. Gen. iv. 223 (1820). —MEX-— 
ICO: Qurretaro: Santa Rosa, 1450 m., Bonpland 4237 (rypr: 
Par., drawing G.). — Apparently a member of the subgenus Am- 
philepis, but I have been unable to identify it with any other 
species. 
143. V. vVERNONIOIDES Baker. Erect herbaceous perennial, 
about 1 m. high, the stem brown, obscurely pilose, branching 
above, the branches arcuate-ascending. Leaves alternate, oblong, 
subremote, sessile, acute, at base rounded, rigid, entire, 3-nerved, 
above green, scaberulous, beneath more pilose and venose-reticu- 
late, 4-5 em. long. Heads 10-12, loosely cymose, the terminal 
head sometimes exceeded by the lateral. Involucre campanulate, 
10-12 mm. wide, 6 mm. high, 3-seriate, the phyllaries subequal, 
oblong, acute, rigid, appressed, sparsely pilose. Rays twice as 
long as involucre. Pales rigid, obtuse, 6 mm. long. Achenes 
oblanceolate, 4 mm. long. Awns triangular, lanceolate, 2 mm. 
long; squamellae a half to a third as long. — Baker in Mart. FI. 
Bras. vi. pt. 3. 223 (1884). — Based by Baker on Manso 216, from 
near Pouzo Alto, on the road to Cuyabé, Matto Grosso, Brazil. 
Not seen; apparently a member of the Bracteatae.

the plant is not a member of this genus.
