subequal and about as long as the calyx-tube or the middle one 
longer, linear, subacute, minutely ciliate ; calyx 3-2 lin. long, 
campanulate, deltoidly toothed to about the middle, obscurely 
8-ribbed, very minutely puberulous, very adhesive to the corolla ; 
corolla 1-14 lin. long, subureeolate-ovoid or -obovoid, contracted at 
the mouth, glabrous; lobes broader than long, rounded, erect; 
anthers exserted, basifixed, 1—8 lin. long, linear, spurred at the base ; 
spurs awn-like, pendant, sometimes nearly obsolete; ovary not 
longer than broad, with 4 compressed angles, becoming subglobose 
in fruit, glabrous. Stmocheilus obovatus, Benth. in DC. Prodr. vii.

Bracts 0, 1 or 3, adpressed to and coming away with the calyx. 
Calyx oblong, obconic, campanulate or tubular, sometimes becoming 
ovoid in fruit, coriaceous or thick and fleshy or thin, 4-toothed ; 
tube 4-angled or 8-ribbed ; teeth usually much shorter than the tube, 
sometimes equalling it. Corolla small, hypogynous, much longer 
than the calyx, tubular, tubular-campanulate or funnel-shaped, often 
curved, minutely 4-lobed, usually more or less 4-angled. Stamens 
4, hypogynous, always exserted when mature ; filaments free, linear 
or filiform, glabrous; anthers free, basifixed or dorsifixed, divided 
nearly to the base, with parallel contiguous cells, with or without 
spurs on the back or at the base; cells opening by oblique pores. 
Ovary seated on a disk, 2-celled, often becoming 1-celled in fruit ; 
style exserted, filiform, glabrous; stigma minute, simple, slightly 
thickened or capitate. Ovule solitary in each cell, pendulous, 
Fruit usually very small, elongated or ellipsoid, often 1-seeded ; 
pericarp usually very thin or in a few species hardened and crusta- 
ceous. 
Small shrubs or shrublets resembling Syndesmanthus ; leaves often with a 
ridge down the middle of the flattened upper side, convex and grooved down 
the back ; flowers solitary or 2 to several in a cluster or head, axillary and 
terminal.

In the measurements of the leaves the length of the petiole is always included. 
It should be understood that in this and in all other genera of South African 
Ericacea, there is no real morphological distinction between the solitary bract 
and a floral leaf, but when it comes away with the calyx it has been gy ted 
to call it a bract, and when persistent on the axis, a floral-leaf. Bil oa os s 
are present, the middle one probably represents the very reduced lea get w = 
axil the flower arises, and the lateral pair two bracteoles developed on - sub- 
obsolete pedicel, which are sometimes present and sometimes roo e 1p
