membranous, about an inch long, oblong-lanceolate, 1-nerved, arch- 
veined, tapering at the base, mucronate at the apex, serrate, serratures 
mucronate, mucros curved. Petioles 4-6 lines long, terete, chan- 
nelled on the upper surface and furnished at the margins with nume- 
rous stipitate glands. Stipules linear-subulate, nearly as long as the 
petioles. Peduncles axillary, about twice the length of the leaf-stalks, 
dividing above into 2-3 bracteate divisions, of which one only bears a 
flower. Bracts linear-subulate, like the stipules, about 2 lines from 
the flower. Flower erect, bell-shaped, whitish, 4—6 lines long. Flower- 
tube very short. Sepals herbaceous, 3-4 times longer than the tube, 
linear-oblong. Petals membranous, white, many-nerved, rather shorter 
than the sepals. Intermediate row of corona membranous, spreading 
or deflexed, about one-fourth of the length of the outer row ; third row 
of the corona rather. longer than the second row. Filaments fat, 
ribbon-shaped, 1-nerved, dilated at the base, attached to the back of the 
linear anthers by a narrowed extremity. Ovary ellipsoidal, glabrous, 
raised on a short stipes or subsessile; styles consolidated for three- 
fourths of their length, dividing above into 8 stigmatic branches. Cap- 
sule nodding, $ in. long, smooth, obtuse at both ends.

divided into 5 oblong-lanceolate overlapping segments. Petals », 
springing from the edge of the flower-tube. Cons of two rows 
emerging from the throat of the flower-tube; outer row membranous, 
jagged at the edge, about half the length of the petals; inner row 
much smaller, consisting of a ring of thick fleshy tubercles. Stamens 
numerous, monadelphous at the base, emerging from the base of the 
flower-tube ; filaments in two rows; anthers linear-oblong, introrse.

shaped. Fruit coriaceous, indehiscent, globose. Seeds ovoid, com
