presence of a corona, which, although very small, is quite evident, and arises on the 
staminal-column at about or a little below the middle.

K—M. A small woody shrub, much branched, the branches sometimes 
twining ; young shoots, petioles, pedicels and calyx all densely and 
minutely tomentose. Leaves rather thick and somewhat fleshy ; petiole 
2-4 lin. long; blade }-1in. long, 2-10 lin. broad, ovate or elliptic, 
obtuse, apiculate or acute. Cymes or fascicles sessile, 2—6-flowered ; 
pedicels 1 lin. long or less. Calyx campanulate, 1 lin. long, 5-lobed to 
half-way down or more; lobes ovate, subobtuse. Corolla apparently 
white or yellowish ; tube campanulate, } lin. long; lobes 34-4 lin. long, 
spreading, linear-oblong, obtuse. Coronal-lobes horizontally spreading 
from about the middle of the filamental part of the staminal-column, 
which is 4 lin. long, furrowed, and more slender than the antheriferous 
portion. Anther appendages broadly reniform, very obtuse, connivent 
around the base of the apical part of the style, which is produced beyond 
them into a subulate, entire or bifid beak 3-1lin.long. Follicles 14-2 in. 
long, $—4in. thick, lanceolate, acuminate, smooth, more or less glaucous. 
Seeds 25-3 lin. long, ovate, plano-convex, scabrid-tuberculate, crowned 
with a tuft of hairs.—K. Schum. in Engl. & Prantl, Pflanzenfam. iv.

Calyx 5-partite. Corolla-tube short; lobes 5, suberect or spreading, 
overlapping to the left, but scarcely twisted in the bud, often tuberculate 
or thickened below the apex. Coronaof 5 lobes arising from the tube of the 
corolla a little above the origin of the staminal-column or at tbe mouth, 
alternating with the corolla-lobes, usually free and variable in form, 
rarely connate into a 5-lobed tube. Staminal-column arising at or below 
the middle of the corolla-tube ; anthers terminated by erect or inflexed 
membranous appendages. Pollen-masses pendulous, solitary in each 
anther-cell, attached in vairs to the pollen-carriers by short or almost 
obsolete caudicles. Style sometimes exserted beyond the anthers. 
Follicles variable, echinate or smooth. Seeds flat, with entire or toothe 
margins, crowned with a tuft of hairs.—Dwarf perennial or rarely 
annual herbs, with opposite leaves. Cymes lateral or sublateral between 
the bases of the petioles, few-or many-flowered, or the flowers solitary, 
small, 
Species few mostly natives of Tropical Africa but extending into North Africa 
and from Arabia to Scinde.
