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

Type
Type: Tanzania, Lushoto District: Usambara Mts, Nyika, Holst 571 (B†, holo.). Neotype: Kenya, Teita District: Voi, Napier 890 (K!, neo.; EA!, iso.; selected by Napper)
Morphology General Habit
Shrubby herb or shrub to 1(–1.5) m tall, erect or somewhat scandent; young stems subglabrous to puberulous or pubescent. Leaves in whorls of 4, sessile or with petiole up to 2(–3) cm long; lamina ovate to elliptic, largest (3.5–)5.5–14(–18) × (1.5–)2–5(–7.2) cm, apex acute to broadly rounded, glabrous to puberulous or pubescent
Morphology Reproductive morphology Inflorescences
Spikes 2–12.5 cm long; peduncle 1–16 cm long, subglabrous to finely sericeous or puberulous; fertile bracts obovate, 11–21 × 5–12(–14) mm, length/width-ratio 1.4–2.2(–3), concave (with distinct “shoulders”) below a recurved pungent mucro 0.5–3 mm long, puberulous and ciliate or densely so on edges and lower part of back, usually also with stalked capitate glands (see note), with 3–5 strong longitudinal veins and raised reticulum; bracteoles (7–)10–20 mm long, puberulous and densely ciliate
Morphology Reproductive morphology Flowers Calyx
Sepals cuspidate, sparsely puberulous and sparsely to densely pilose on back (sometimes only on midrib), glabrous towards base, ciliate or densely so, dorsal broadly elliptic, 8–13 mm long, ventral ovate-elliptic, 9–15 mm long, lateral 6–11 mm long
Morphology Reproductive morphology Flowers Corolla
Corolla pale orange to orange or salmon pink to bright red; tube yellow, 15–24 mm long, bent near insertion of stamens, upper part infundibuliform; limb 10–18 mm long
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens inserted near middle of tube.
Morphology Reproductive morphology Fruits
Capsule 9–14 mm long
Morphology Reproductive morphology Seeds
Seed 3–4 × 2.5–3.5 mm
Figures
Fig 22, p143
Ecology
Acacia-Commiphora woodland and bushland on sandy to loamy or stony soil or on rocky slopes and outcrops, dry upland forest and dry riverine forest and thicket; 0–1500(–2200) m
Note
Specimens from the northern part of our area ( U 1, K 1, 2, 3 and part of K 4) have many capitate glands on the bracts, while specimens from Tanzania and the southern part of K 7 are usually without glands. Specimens from central Kenya vary between these two. This is a useful additional character for separating C. mucronata from C. subacaulis in Uganda where some collections are otherwise more or less intermediate. The bracts in C. subacaulis have no or only a few scattered glands.
Distribution
