cels 10, linear, horny, dehiscing outwardly, erect, propped by 
corpuscles at the base, and applied to the furrows of the stigma ; 
pollen granular. Stigma 5-angled, and having 5 deep furrows. 
Ovarium didymous. Style one, thick —A twining shrub, with 
opposite, elliptic-oblong, acutish, veiny, glabrous leaves, which 
are paler beneath. Peduncles interpetiolar, bifid. This genus 
differs from Periploca in the anthers being sessile and inclosed, 
and from the number and singular form of the polliniferous 
pedicels.

Flowers of equal parts. Calyx free, 5-parted. Limb of 
corolla equal or unequal, convolute in z&stivation. Stamens 5 
or l, rising from the corolla; pollen vittately 3-lobed (in Pa- 
gamea). Stigma simple. Fruit a 2-celled, bipartible capsule ; 
having placenta adnate on both sides to the segment of the ven- 
tral suture, many-seeded ; or a drupe, containing 1-2 1-2-seeded 
pyrene. Albumen fleshy or cartilaginous. Embryo straight.— 
Herbs, shrubs, or trees. Leaves opposite, quite entire, usually 
stipulate. Stipulas combined into intrapetiolar sheaths. Flowers 
racemose, corymbose, or solitary, usually white. 
This order is distinguished from Gentiànec in the capsule 
being divisible into 2 1-celled parts or drupaceous, in the pla- 
centation of the seeds, in the estivation of the corolla, in the 
stipulate leaves, and in the fleshy or cartilaginous albumen, &c.
