68 “ADDISONIA 
constitute the subgenus Ewuagave. The usually narrow-leaved 
species with flowers condensed in a wand-like spike, represented 
by the “lechuguilla” of western Texas, belong to the subgenus 
Littaea; usually the flowers of a Litiaea are in pairs. Normal 
plants of Agave subsimplex form unmistakable if reduced panicles 
and the species is clearly a Euagave. The transplanted specimen 
now figured not only lacks characteristic leaves, which have fallen 
from its bulb-like trunk, so that it possesses only the transition 
stage that is found about the base of the scape, but its flowers 
have been reduced to two at each node, quite as in Littaea. Mis- 
understanding of a similar depauperate inflorescence caused another 
of the Mexican species, the ‘‘espadilla’’ of Tehuacan, Agave 
macroacantha, to stand for many years in the spicate group, though, 
like A. subsimplex, it is clearly a Euagave in flowers and fruit, and 
also in its normally developed panicle.
