M. Thulin et al. Flora of Somalia, Vol. 1-4 [updated 2008] https://plants.jstor.org/collection/FLOS

Habit
Prostrate ascending or erect annual to perennial herb, up to 25–40 cm tall or more
Stem
Stems green to greyish green with a sparse to fairly dense indumentum of up to 3 mm long irregularly spreading hairs
Leaves
Leaf-blades lanceolate to broadly ovate, up to 26–65 x 10–55 mm, sparsely pubescent with somewhat antrorse up to 2 mm long hairs along veins and margins, apex obtuse or acute, base shortly attenuate; petiole up to 4–15 mm
Flowers
Flowers single at upper nodes on peduncles c. 1 mm long; bracteoles leaf-like, up to 10–15 x 4–11 mm with petiole up to c. 2–4 mm long
Calyx
Calyx-lobes narrowly triangular-subulate, often with a prominent hyaline margin, densely pubescent with 0.3–1 mm long somewhat antrorse hairs, up to 6–15 x 1 mm at flowering, slightly enlarged in fruit
Corolla
Corolla mauve to deep blue, up to c. 20–35 mm long; tube narrowly funnel-shaped, 13–22 mm long; lobes free from each other for up to 6–10 mm
Anthers
Anthers c. 2.5 mm long
Fruits
Capsule elongate and slender, c. 12–16-seeded, 16–22 mm long, finely pubescent with appressed 0.1–0.3 mm long hairs.
Distribution
N1, 2; S1, 3 Eritrea, Ethiopia, Sudan and south to South Africa, also on the Arabian Peninsula and eastwards to southern Asia and the Pacific Island.
Ecology
Altitude range 25–1650 m.
Vernacular
Arcut (Somali).
Note
As they agree with R. prostrata in capsule shape and indumentum, they are here provisionally included in this variable species, but revision of the whole complex seems necessary before any clear conclusion regarding their status can be drawn. Prostrate-ascending, narrow-leaved forms have been treated as R. sudanica (Schweinf.) Lindau

Acanthaceae (part 2), Kaj Vollesen. Flora of Tropical East Africa. 2008

Type
Type: India, Dupuis s.n. (P, holo.)
Habit
Erect to decumbent perennial herb to 50 cm tall with several stems from woody rootstock or erect to scrambling subshrub to 1.5 m tall; young stems subglabrous to densely puberulous, pubescent or pilose with broad glossy straight or curly spreading or upwardly directed non-glandular hairs
Leaves
Leaves with petiole (0–)3–20(–30) mm long; lamina lanceolate to broadly ovate or broadly elliptic, largest (3–)4–10(–14) × (0.5–)1–6(–7) cm, apex acute to rounded, base attenuate to truncate, subglabrous to pubescent, densest along veins
Flowers
Flowers solitary or in 2–3-flowered axillary cymes; pedicels 1–2.5 mm long, glabrous to puberulous; bracteoles (bracts in cymes) lanceolate to broadly ovate, 7–23 × 2–16 mm
Calyx
Calyx (6–)9–23(–27) mm long, divided to 1–3 mm from base, with filiform pubescent- to pilose-ciliate lobes with hairs to 2 mm long, otherwise glabrous to puberulous. Corolla falling early in the morning, white to mauve or purple; tube 14–28 mm long of which the basal cylindric part 4–10 mm and the throat 11–21 mm; lobes 6–16 × 5–14 mm, elliptic or broadly so with entire to crenate-dentate edge. Stamens included in throat, didynamous, anthers not or slightly overlapping; filaments fused for 1–2 mm at base, free parts 2–4 and 5–8 mm long; anthers 1.5–3 mm long
Ovary
Ovary densely puberulous.
Stigma
Ventral stigma lobe 1–2 × ± 0.5 mm.
Fruits
Capsule narrowly oblanceolate to clavate, puberulous to sericeous (very rarely glabrous), (13–)15–24 mm long, (6–)8–16-seeded
Seeds
Seed ovoid to orbicular, grey to brown, 3–4 × 3–4 mm
Figures
Fig. 31, 10–11, p206
Ecology
In a wide variety of grassland, bushland and woodland on an equally wide variety of soil types; near sea level to 1500 m
Note
Burtt 1134, Tanzania, Kirangi, Mburi has a glabrous capsule but seems from other characters to be R. prostrata. For the moment it is best kept in this species. C.B.Clarke in F.T.A. expresses some doubt as to whether the type specimen of R. prostrata is distinct from R. patula. It is however apparent that the Indian material of R. prostrata generally has a shorter calyx than the East African material. But the shape of the calyx lobes and calyx indumentum is still distinct. A many-formed species which may eventually prove to contain several infra-specific taxa, but extensive field studies will be needed to confirm this. All plants under this species are linked by the filiform calyx lobes and the hairy capsule. The leaves are generally larger and more acute than in R. patula.
