liptic-roundish, obtuse at both extremities, 
each of them enveloping a single soli 
seed, by the side of which the abortive 
ovule is still observable. Seeds attached 
on the base of the posterior face of the 
placentas (in the angle originally formed 
by the corresponding dissepiment) by a 
short filiform ascendent funicle, orthotrop- 
ous, arrect, minute, nearly as long as the 
placentas, ovate, trigonal (convex on their 
posterior, carinate on their anterior surface) 
smooth and shining, reddish-brown, and 
pellucid enough to allow the embryo to be 
seen through; tegument thin, crustaceous, 
micropyle punctiform, terminal ; hilum and 
chalaza confluent in a brownish basilar 
areola; perisperm thin, corneous; embryo? 
rectilinear, or nearly so, axils antitropous, 
about as long as the perisperm ; cotyledons 
somewhat narrower than the greatest 
breadth of the seed, thin, flat, elliptic; ra- 
dicle. pointing to the apex of the seed, of 
about the same length as the cotyledons, 
cylindrical, obtuse, straight, quite perpen- 
icular to or a little oblique, in respect to 
the axis of the seed. 
This species makes one of the collection 
of plants found by Mr. Drummond near 
A pallachicola, in Florida (v. specimen uni-
