obtuse to rounded or subcordate at base, scabrous on both sides, espe- 
sua or depressed inflorescence pubescent; peduncles about 1 
ong; heads 21-flowered; involucre broadly campanulate, 7 
mm. high; scales closely Se ey appressed, glabrous, the ex- 
posed portion purple, the outer lanceolate, cuspidate, the inner nar- 
rowly oblong, attenuate or sharply acute, mucronulate; achenes 
mm. long, ieee sugebeds sharply ribbed; pappus nearly 
white, 7 mm. long, outer series indistinct. 
Type: Prixgle 2165 from Guadalajara, Jalisco; inthe Gray Her- 
barium. Here are also referred Pringle 298g and 999¢, from the 
same locality, and Palmer 745 from Rio Blanco, Jalisco. One 
sheet of Préxgle 999¢ has narrowly oblong-oblanceolate leaves 
narrowed at the base. In other respects it is like the type, and a 
second sheet of the same number has normal leaves. 
Vernonia jaliscana has been distributed as V. serratulozdes, 
with which it is undoubtedly closely related, as shown by the char- 
acter of the inflorescence, the shape and color of the involucre, the 
general habit of the plant, and its geographical distribution. It is 
amply distinguished by its broad, very scabrous leaves, its 21- 
flowered heads, and more attenuate involucral scales.
