C. enervis sensu Leon & Alain, 1951: 238.

Stiffly repeatedly branched, microphyll, arborescent shrubs flowering when l-3.5(-4) m tall, with virgate, ± zigzag, fuscous, evanescently foliate long-shoots and very short, often crowded, densely thatched brachyblasts, except for rudimentary caducous puberulence of young stems glabrous throughout, inconspicuously armed at some nodes by pairs of firm ascending, ±5-angulate, finally deciduous primary stipules, the small fleshy lfts lustrous above, the few-fld capitula subsessile on brachyblasts; phyllotaxy distichous. Stipules of primary lvs ±1-1.8 mm. Lf-formula i/1, each lf 4-foliolate; petioles and pinna-rachises cuneate, shallowly excavated ventrally, 0.6-1.8 mm; lfts sessile, oblong-obovate or obovate from shallowly semicordate base, broadly obtuse or obscurely apiculate, 1.6-4 x 1.2-2.2 mm, 1.3-2.3 times as long as wide, the externally nerveless blade biconvex along the line of the midrib, plane toward margin. Peduncles 1.5 mm or less; no bract seen; capitula (l—)2—5-fld, the receptacle scarcely 1 mm; floral bracts subulate ±1 mm; perianth either 4- or 5- merous, glabrous, the calyx and corolla both 8-15- nerved; calyx campanulate 1.7-2 x 0.8-1 mm, the lance-subulate teeth 0.6-0.8 mm; corolla 3.7-4 mm, the lanceolate lobes 1.5-2 mm; androecium 18-24- merous, 12-14 mm, the stemonozone ±0.9 mm, the tube 1.6-2 mm, the tassel red; intrastaminal disc 0; ovary subsessile, glabrous. Pods erect, in profile 2840 x 5-6.5 mm, 3-4-seeded, glabrous overall, the sutural ribs in dorsal view 1.5-1.8 mm wide, the plane leathery, dark brown valves externally nerveless; seeds not seen, according to Bässler (1990) 4-5 x 3 mm, pleurogrammic.
