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 cm. 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 20i)0 m., 

 18 October, 1895, Rev. Lucius C. Smith, no. 971 (lib. Gr.) ; without 

 locality, 21 October, 1899, E. W. D. Holway, no. 3689 (hb. G-r.), July- 

 August, 1900, Conzatti fy Gonzalez, 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 cm. long, 1 to 2.5 cm. broad, acuminate, acute, entire ©r 

 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 cm. 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, E. 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.
