M. Thulin et al. Flora of Somalia, Vol. 1-4 [updated 2008]

Unarmed shrub up to c. 3 m high, much branched; young branches with a dense off-white tomentum, older stems glabrescent, with a dark red-brown, later greyish-black bark
Leaves crowded towards the ends of new branches or on short shoots, occasionally leaves scattered along new shoots with active growth; petiole 5–10 mm long; blade broadly ovate to elliptic or elliptic-oblong, 1–5.5 x 0.8–4 cm, base usually rounded, sometimes truncate to cuneate, margin entire, apex rounded to acute, membranous to somewhat leathery, both surfaces sparsely to moderately tomentose with equal-rayed stellate hairs, but upper surface often less hairy and dark green, lower surface pale green
Inflorescence terminal on short shoots or sometimes lateral or terminal on long shoots, umbel-like, few-flowered; peduncle absent or very short; pedicel c. 1 cm long, recurved in fruit
Calyx 3–5 mm long, lobes narrowly triangular, abruptly acuminate, spreading away from the fruit
Corolla violet, stellate, deeply lobed, with a dense tomentum of stellate hairs outside, c. 2 cm in diam., lobes narrowly lanceolate
Anthers c. 4 mm long, yellow
Style exceeding the anthers with c. 4 mm
Fruit globose, yellow, c. 8 mm in diam.
N1–3; C1, 2; S1, 2; E Ethiopia, NE Kenya
Altitude range 50–1300 m.
The syntypes of S. jubae, collected by Keller, are not from Somalia but from present-day Ethiopia.

Type: Somalia, “Djuba Steppe, Elmeged,” Keller s.n. (Z, syn.) & Webi Suabeli (?Schebeli), Keller s.n. (Z, syn.)
Shrub, spreading, straggling or much branched from the base to 3 m high, unarmed; young stems smooth, reddish-brown, stout at maturity, often lenticellate and bearing prominent leaf scars, with dense yellowish tomentose indumentum of 8-equal-rayed eglandular stellate hairs when young, glabrescent
Leaves often clustered around short shoots on the stem and opposite in pairs or threes, rough, yellowish to light green, orbicular to ovate, 1–2.4(–4.5) × 0.5–2.7 cm, bases cuneate, margins entire, apices rounded to obtuse, rarely acute; both surfaces with tomentose indumentum of stellate hairs larger than those on stems but with shorter erect central rays, bulbous basally, hairs densely interlocking on lower surfaces, on upper surfaces lamina visible between hairs; petioles 2–10 mm long
Inflorescences terminal up to 8-flowered umbellate cymes, or lateral when on short or long shoots and solitary or 2–3-flowered cymes; peduncles absent or vestigial; pedicels erect and 2–11 mm long in flower, recurved and 2.5–12 mm in fruit, stellate-tomentose
Calyx campanulate, 2–4(–5) mm long, stellate-tomentose externally; calyx lobes triangular (ovate), 1–2(–3.5) × 1–1.5(–2) mm, acute to apiculate (obtuse); adherent becoming reflexed in fruit, (1–)2.5–4 × 1.2–3 mm, sometimes unequal. Corolla pale lilac to purple and cream, stellate, 16–28 mm diameter; tube 1.5–2 mm long, glabrous externally; lobes narrowly lanceolate, 5–11 × 1.6–3 mm, densely stellate-pilose externally, glabrous internally, strongly reflexed exposing androecium after anthesis
Stamens usually equal and connate; filaments free for ± 0.5 mm, glabrous; anthers yellow to brownish, poricidal, often with orange pores, 4.6–7.6 × 0.6–1.4 mm, free and often spreading at maturity
Ovary brownish, 1.2–2 × 1–1.4 mm, glabrous to stellate-pubescent, occasionally mixed with simple hairs; style often curved apically, 6–11 × 0.2–0.5 mm, hairy on lower half with a dense collar of mainly simple hairs at junction with ovary, always exserted 2–5 mm; stigma capitate, 0.4–1 mm diameter
Berries mottled green and white maturing to yellow/orange, globose to ovoid, 4–9 × 5–11 mm, with scattered stellate hairs, sometimes with unpleasant smell
Seeds 7–22 per berry, light brown to golden yellow, ovoid, discoid or reniform, 2.1–3 × 1.8–2.8 mm, foveolate; sclerotic granules absent
Fig. 23/1–6, p 188
Acacia-Commiphora woodland or mixed bushland , often on steep slopes, limestone ridges and valleys; 350–500 m
Specimens typically exhibit open flowers in one-, two- or three-flowered cymes. However, many juvenile terminal inflorescences have up to 8 flower buds, and it is possible that not all of these develop to maturity. Herbarium material of this species is generally poor, often consisting of a few leaf fragments on bare woody stems; these are however characteristically tough and multi-angular with smooth reddish bark. Thulin (2006) noted that the syntypes of S. jubae cited by Keller are from present day Ethiopia and not Somalia. This species is grazed by goats in Somalia.
