 multo breviores. — Hidalgo (?) : between Rio Grande and Jamaltepec 

 (?), Dec. 1829, C. Ehrenberg 1227 (types in the Berlin Herb, and the 

 Gray Herb.). — From its nearest ally, V. brevifolia Greenm., the 

 present species differs chiefly in foliar characters. The leaves of V. 

 brevifolia are ovate to triangular-ovate, usually acute but sometimes 

 obtuse, and usually strongly canescent above, on petioles 2-3 mm. 

 long; the awns of the pappus about 1 mm. long, equalling the squa- 

 mellae. Ehrenberg's plant in the Berlin Herbarium was marked as a 

 new species under an unpublished generic name equivalent to Gym- 

 nolomia by Schultz Bipontinus, who could scarcely have given it more 

 than a very casual inspection to refer it to this genus the salient 

 character of which is the absence of pappus. 



Viguiera Brandegei Blake, n. nom. — Asyilia hispida Brandegee! 

 Univ. Calif. Pub. Bot. iv. 94 (1910), not Viguiera hispida Baker in 

 Mart. Fl. Bras. vi. pt. 3. 220 (1884).— The pappus of this species, of 

 about 4 oblong irregularly lacerate squamellae with 1 or 2 longer 

 similar aristae, is that of Viguiera rather than Aspilia. Among 

 Mexican species V. Brandegei is most closely related to V. tenuis 

 Gray and V. gracillima Brandegee. The species is renamed in honor 

 of its original describer, whose publications have for many years been 

 adding largely to our knowledge of the flora of Mexico and Lower 

 California.
