New or noteworthy Composite from Guatemala. 
JOHN M. COULTER. 
WITH PLATES V AND VI. 
Capt. John Donnell Smith has submitted to me his recent 
collections of Composite from Guatemala, and the following 
results are thought worthy of publication. All of the most 
critical material was taken to the Gray Herbarium and Li- 
brary for final study, where every facility for work was pro- 
vided through the courtesy of the curator, Dr. B. L. Robin- 
n. 
VERNONIA CANESCENS HBK.—Aquacatepec, Depart. Zaca- 
tepequez, alt. 4,300%, March 1892, Yokn Donnell Smith 
2,837. Apparently quite common from Peru and Venezuela 
to Panama. Reported also from Nicaragua (Wright) and 
Huasteca (Ervendberg). Very closely related to V. gemin- 
ata Less. of Brazil, and often confounded with V. arborescen 
w. of Central America. 
Vernonia Luxensis, n. sp.—A shrub 3™ high, glabrous ex- 
cept more or less pubescence in the inflorescence which forms 
large pyramidal clusters of more or less leafy panicles: leaves 
oval, tapering at both ends and petioled, upper ones often 
Narrower, entire or obscurely toothed: involucral scales in 
five or six tows, innermost ones linear-oblong and often quite 
clongated, the outer ones gradually passing into much broader 
and shorter forms, all sharp pointed and membranous except 
for the greenish center and tip: heads 3 or 4-flowered, 
cylindrical, more or less pedicellate: achenes strigose pubes- 
cent, often densely so.*Santa Rosa, Depart. Santa Rosa, alt. 
34,000", April 1892, Heyde & Lux 3,421. 
Very nearly related to V. Palmeri Rose from Alamos (N. 
- Mexico), but differing in pubescence, leaves and involu- 
Cral scales
