Morphology General Habit
Spiny shrublet c.40 cm tall, much-branched; stems densely pubescent with white retrorse or spreading hairs, nodes strigose; internodes short.
Morphology Leaves
Leaves elliptic to lanceolate, 0.9–1.4 × 0.3–0.6 cm, base attenuate to obtuse, apex narrowed into a short spine, strigose mainly on margin, midrib and veins beneath; lateral veins 3–4 pairs; petiole to 2.5 mm.
Morphology Reproductive morphology Inflorescences
Inflorescence a contracted unilateral cyme 1–2.5 cm long in upper axils, each 2–8-flowered, sometimes only one flower developed at a time; bracteoles spinose, pairs unequal in length, the longer 9–17 × 0.5–1 mm, margin entire or with 1–3 short lateral spines to 1 mm long, numerous sterile bracteoles present at lower nodes as axillary spines, often two pairs per axil.
Morphology Reproductive morphology Flowers Calyx
Calyx at first mauve, paler towards base and with darker venation, later turning pale-scarious; anterior lobe lanceolate, 8.5–14 × 2.5–4 mm, base shortly attenuate, margin with 2–5 short lateral spines 0.5–1.5(2.5) mm long ending in a short bristle, apex spinose or bifidly so, surface strigulose along veins, often with scattered patent glandular hairs; posterior lobe as anterior but 11.5–20 × 3.5–5 mm, marginal spines 1.5–3(6) mm long, apex attenuate into a long spine; lateral lobes linear-lanceolate, 7–9.5 mm long.
Morphology Reproductive morphology Flowers Corolla
Corolla (22)25–37 mm long, lilac or blue-mauve, pubescent externally with mixed glandular and eglandular hairs; tube (13.5)15–24 mm long, cylindrical, narrowly campanulate towards mouth; limb in weak 2+3 arrangement or subregular; abaxial lobe (8)10.5–14 × (6)7–10.5 mm; lateral lobes (8)9.5–13 × (5)6–10 mm; adaxial lobes (7.5)9.5–12 × 4–7.5 mm.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens attached ± midway along corolla tube; filaments (12)19–22 mm long; anthers 2–2.5 mm long; lateral staminodes (1)2–3 mm long, pubescent towards base, antherodes to 0.6 mm long or barely developed.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary with a ring of minute crisped white hairs at apex; style glabrous; stigma linear, 0.4–0.6 mm long.
Morphology Reproductive morphology Fruits
Capsule 9–12.5 mm long, glabrous.
Morphology Reproductive morphology Seeds
Mature seeds not seen.
Not known elsewhere.
Granite hillslopes and inselbergs, usually amongst large boulders in partial shade or in open woodland; 600–1550 m.
Conservation notes: Endemic to the central watershed of Zimbabwe, a very local species known from few collections but its favoured habitats are not threatened; probably Least Concern.
