Tribe IV. 
GELSEMIE"/E. Fruit of 2 joined follicles, which are at 
length separable, 2-valved, 2-celled ; valves 1-celled, with in- 
flexed, seminiferous edges, which constitute the dissepiment. 
Seeds flat, winged. This tribe seems to connect the Gentidnee 
with Apocinee, through Cramfirdia.

Corolla large, funnel-shaped ; with a 5-cleft, almost equal limb. 
Stigma trifid. Capsule ovate-oblong, rather compressed, 2- 
celled, composed of 2 joined follicles, which are separable, fur- 
rowed in the middle; 2-valved; valves keeled, with inflexed 
edges, which constitute the dissepiment. Seeds numerous, flat, 
imbricate, meinbranous at the apex, fixed to the edges of the

readily under a hand-glass. 
XXVIII. PLECTANETA (meaning unknown.) 
gen. mad. no. 35. Reem. coll. p. 203. 
Lin. syst. Pentandria Monogynia, Calyx urceolate, 5-cleft, 
or 5-toothed. Corolla with a short ventricose tube, and a 
twisted, coarctate limb. Anthers sessile, sagittate. Ovarium 
solitary. Style short; stigma capitate. Capsule follicular, very 
long, sub-tetragonal, 2-celled, probably composed of 2 joined 
folicles ; with introflexed, seminiferous edges. Seeds com-

funicles. Albumen thin. Embryo straight, with flat cotyledons. 
—A lactescent, twining shrub; with opposite leaves, and small 
corymbose flowers. Fruit like that of Bignónia. The genus is 
said to be nearly allied to Gelsemium by some, and by others 
to Plumiera, but totally distinct from both.
