Trelease—The Agaveae of Guatemala. 139 
Thomas, Quezaltenango (Trelease, 19, April, 1915—the 
type). 
Thinner-leaved and smaller-toothed than the Guate- 
malenses as otherwise known, and resembling certain of 
the Mexican aloid Littaeas—to which it may prove ul- 
timately to belong. It is said to have come from the 
Guatemalan mountains, and is dedicated to Sefiora Dora 
Thomas, the possessor of the type plant.
