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 Senora Dora 

 Thomas, the possessor of the type plant.

 lightly glaucous, widely spreading, oblanceolate, acute, 

 more or less concave, minutely roughened especially on 

 the back and margin, some 10x100 cm.: spine purplish 

 brown, somewhat glossy above, minutely granular be- 

 low, slenderly conical or acicular, more or less flexuous, 

 involutely grooved from about the middle with acute 

 edges, decurrent for about its own length, scarcely in- 

 truded into the green tissue, 3-4x40 mm. : teeth chest- 

 nut, 10-20 mm. apart, 2-4 mm. long, straight or curved, 

 especially downward, the slender triangular cusps len- 

 ticularly dilated into the straight margin. Inflorescence, 

 flowers and fruit unknown.
