had seen the filaments shorter and longer in different flowers 
of Agave vivlpara; which is a most inconclusive reason. 
Length of stamens is a very variable feature, insufficient, I 
should think, in most cases to support a generic character, 
but that of Fourcroya does not depend on it. I have inserted 
filaments short in a parenthesis, as a feature probably per- 
vading the whole genus, though not necessarily. A plant 
would be equally a Fourcroya, however long its filaments 
might be, with the formation described. 
26. Agave. — Bulb imperfect, or long-lived stem ; perianth 
tubed, limb not patent ; filaments adnate to the tube, 
filiform (long) ; anthers long, versatile ; style trian- 
gularly filiform ; capsule attenuated at both ends, 
3-valved, 3-celled ; seeds black, numerous. 
§. 1. Germen cylindrically oblong, pedunculated, hori- 
zontal ; limb funnel-shaped ; filaments inserted 
at the mouth of the tube ; stigma capitate, 
scarcely lobed. Genus Chloropsis? Milii. Spec. 
Lurida. PI. 33. f. 16-19. 
§. 2. Germen oval, sessile, nearly horizontal ; limb revo- 
lute; filaments inserted in the base of the seg- 
ments ; stigma inconspicuous. Genus Littgea ? 
Haworth. Spec. Geminiflora. 
§. 3. Germen oblong-oval ; perianth erect or assurgent, 
limb pressed against the filaments ; stigma 
3-lobed, lobes emarginate. Genus Agave. Spec. 
Virginica. 
This genus requires to be carefully re-examined. I can- 
not allot the species to the three sections, but have stated the 
species which are their types, having had no opportunity of 
inspecting them. 
The flowers of five species named by Zuccarini are not 
described. They are at present only known by the leaf.
