70 PENTANDRIA DIGYNIA. Gentiana, 
Ma.e flowers numerous, small, and collected on 
small, axillary, solitary short-peduncled fascicles. Calyx 
five-leaved ; leaflets oval, hoary. Petals five, length of 
the calyx, but narrower and smooth, Nectarial scales five 
on the base of the petals, small, oval, alternate with the 
filaments. Filaments five, from the receptacle, alternate 
with the petals, and shorter than them ; anthers cordate. 
HERMAPHRODITE FLOWERS on a different tree and 
disposed asin the male. Calyx, corol, nectary, and sta- 
mina as in the male. Germ ovate, cordate, a little com- 
pressed, downy, two-celled, with two ovula in each, at- 
tached from the apex to the top of the cells. Styles 
two, recurved. Stigmas somewhat two-lobed. Capsule 
transversely oval; two-lobed, soft, with grey olive-colour- 
ed down, size of a nutmeg, two-celled, two-valved, open. 
ing round the apex. Partition slender. Seed (nuts ?) one 
in each cell, or lobe of the capsule, oblong, more convex, 
on the outside completely covered with a soft scarlet 
or exterior tunic. Integuments two besides the red aril ; 
exterior of a tough fibrous ensiform texture, and very 
rugose on the outside ; inferior soft, and spongy. Peris- 
perm none. Embryo inverse ; cotyledons two, conform to 
the seed. Plumula from two to five-lobed, Radicle short, 
superior, ; 
In habit this tree approaches Willdenow’s two Geloni- 
ums, and in the structure and contents of the germ and 
mature seed vessel, they agree almost exactly, except in 
the absence of a perisperm in this ; yet their flowers dif- 
fer widely, here they are pentandrous with a five-petalled 
corol, male on one tree and hermaphrodite on another; 
completely dioecous, no corol, polyandrous,
