Viguiera eriophora. Stem somewhat ligneous, covered with a 
brownish bark ; branches and branchlets reddish-brown, striate, more or 
less compressed, tomentulose, lanate at the nodes as well as on the 
petioles with long woolly hairs: leaves mostly opposite, ovate to ovate- 
lanceolate, including the petiole 5 to 16.5 cm. long, 1 to 8 cm. broad, 
acuminate, acute, coarsely and irregularly dentate, abruptly contracted 
at the base and more or less decurrent on the petiole, tuberculate-hispid 
above, hirsute-pubescent beneath, 3-nerved, rather prominently reticulate- 
veined on the under surface: inflorescence a terminal many-headed sub- 
corymbose cyme; peduncles 0.5 to 3 cm. in length, hirsute-pubescent: 
heads large, including the bright yellow rays fully 4 cm. in diameter, 
1 to 1.5 em. high; involucral scales 3-4-seriate, lance-oblong, short- 
acuminate, acute, tomentulose to nearly or quite glabrous, conspicu- 
ously ciliate, the outer scales somewhat shorter: ray-flowers 6 to 8: 
disk-flowers numerous: achenes densely appressed-sericeous-villous. — 
Mexico. State of Oaxaca: hills of Telixtlahuaca, altitude 2000 m., 
18 October, 1895, Rev. Lucius C. Smith, no. 971 (hb. Gr.) ; without 
locality, 21 October, 1899, Z. W. D. Holway, no. 3689 (hb. Gr.), July- 
August, 1900, Conzatti § Gonzdlez, no. 987 (hb. Gr.). 
In general appearance Virguiera eriophora resembles certain species 
of Helianthi, but in the technical characters of the head it is distinctly 
a Viguiera. 
Viguiera Goldmanii. Stem erect, strict, striate, brownish, glabrous 
or slightly puberulent above: leaves opposite, subsessile, oblong-lance- 
olate, 5 to 8 em. long, 1 to 2.5 em. broad, acuminate, acute, entire or 
inconspicuously denticulate, subcordate at the base, sparingly hispidulous 
on both surfaces, distinctly 3-nerved: inflorescence a loose di-trichoto- 
mously branched corymbose cyme: heads 10 to 12 mm. high, radiate, 
including the rays about 2.5 cm. in diameter: involucre subcylindrical, 
slightly shorter than the flowers of the disk: bracts of the involucre 
4-5-seriate, ovate-oblong to typically oblong, obtuse to rounded at the 
apex, yellowish green, glabrous and _ striate, short-ciliate: ray-flowers 
commonly 8; rays oblong, about 1 em. long: pappus of two paleo-aristate 
‘awns, much longer than the intermediate lacerated scales: achenes 
densely appressed-sericeous-pubescent. — Mexico. State of Durango: 
Chalco, altitude about 1000 m., 7 March, 1899, HZ. A. Goldman, no. 359 
(hb. Gr.). : 
A species resembling Viguiera montana, Rose, but readily distin- 
guished by the more rounded and less ciliated involucral scales, and by 
the less attenuated foliage.
