multo breviores.— Hrpaxco (?): between Rio Grande and Jamaltepec 
(?), Dec. 1829, C. Ehrenberg 1227 (rvpes 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 Fs 
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new species under an unpublished generic name equivalent to Gym- 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. 
Vicurera Brandegei Blake, n. nom.— Aspilia 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 
exican 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 
alifornia.
