Now that communications with Mexico are so frequent, we 
ought to expect many more species of this genus, all of which 
are worth the cultivator's care. Æ. coccinea, with a leafy 
spike of scarlet flowers, yellow inside; Æ. teretifolia, whose 
flowers are of the same colour, but whose leaves are tapering, 
still remain to be introduced ; and even the old Æ. cespitosa, 
with the habit of the species now figured, but with yellow 
stalkless flowers, is seldom or never seen, although cultivated 
years ago. In addition to these there are several species 
not yet described, to which, from the general beauty of the 
genus, some importance is to be attached.
