Morphology General Habit
Wiry dwarf shrub 7– 40 cm high (rarely to 1 m, and twice reported to 1.8 m, in sheltered situations at lower altitudes), much branched, erect or spreading, with short densely leafy side branches 0.5– 5 cm long and long terminal flowering shoots; stem brown to red; branchlets minutely pubescent with simple hairs, intermixed with sparse dendritic hairs 0.3– 1.2 mm long, sometimes intermixed with dense glandular hairs 0.1– 1.2 mm long which may or may not have minute side-branches near their base.
Morphology Leaves
Leaves in whorls of 3(– 4), rarely with spirally inserted leaves, porrect or spreading (less often, in moister situations), fleshy, narrowly elliptic or lanceolate, 0.9– 6 mm long, 0.3– 1.3 mm wide, sulcate beneath, acute, indument variable from sparse to dense, and variable from glandular hairs only to a mixed pubescence of simple and branched hairs, or ciliate with only marginal hairs or stalked glands, or glabrous with only a branched apical hair to 0.6 mm; petiole 0.1– 0.4 mm long, usually puberulous.
Morphology Reproductive morphology Flowers
Flowers on small side branches, forming apparent verticillasters 1– 15 cm long, also some solitary and axillary to distant leaves; pedicel 0.2– 1.7 mm long, puberulous or less often glabrous bract leaf-like, 0.6– 1.6 mm long; bracteoles reduced or missing.
Morphology Reproductive morphology Flowers Calyx
Sepals 4, green or reddish, ± equal, narrowly ovate or linear, 0.5– 2 mm long, 0.2– 0.5 mm wide, apex acute, gibbous, ciliate with simple and branched hairs or stalked glands.
Morphology Reproductive morphology Flowers Corolla
Corolla pink, less often whitish or violet, 4-merous, infundibuliform or shallowly cup-shaped, 0.8– 4.5 mm long, diameter at the mouth 0.6– 1.5 mm, the lobes 0.3– 0.7 mm long, rounded to subacute.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens dark purple, 4(– 5), with filaments 0.2– 3.5 mm long; anthers partly exserted, 0.2– 0.7 mm long, with basal tails 0.1– 0.5 mm long or absent.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary globose or slightly 4-lobed, puberulous; style red, 0.1– 5 mm long, stigma red, capitate, 0.1– 0.3 mm in diameter.
Morphology Reproductive morphology Fruits
Fruit globose, ± 1 mm, puberulous, first widening, then splitting the lower part of the corolla tube.
Figures

Habitat
Short grassland, rock outcrops, stony hillslopes and -crests, moorland, heath zone and bamboo clearings, less often in swamp edges and forest edges; may be locally common or co-dominant (e.g. around Horombo Hut on Kilimanjaro, on the Lukwangule Plateau); (1350– )1800– 4000(– 4500) m

Morphology General Habit
Small shrubs or shrublets to 1 m. tall, branched from the base, with more or less dwarfed branchlets arising from the axils of the leaves.
Morphology Branches
Branchlets without infrafoliar ridges, pubescent with very short simple hairs and longer hairs, mostly with side branches on their basal part and with tips either glandular or eglandular and usually bifurcate, glandular hairs up to 0·9 mm. long, eglandular hairs to 2·0 mm. long, the proportions of the two types varying from all of one to all of the other; occasionally some branchlets of a plant glabrous.
Morphology Leaves
Leaves in whorls of 3, patent on the main stems, somewhat ascending on the dwarfed side shoots, straight or recurved, margins reflexed but normally not quite meeting in the centre line on the abaxial side of the leaf, 1·5–5·0 mm. long, 0·2–1·0 mm. broad, normally pubescent with short simple hairs over the whole dorsal surface of the leaf and widely spaced longer hairs, up to 0·8 mm., at the apex, on the apparent margins and on the abaxial part of the dorsal surface of the leaf, these longer hairs either glandular or eglandular and usually bifurcate, eglandular hairs occasionally with a few side branches at the base; short simple hairs sometimes few and caducous, sometimes absent, and occasionally longer hairs much reduced in number or leaf entirely glabrous with sessile glands along the apparent margin; petioles c. 0·5 mm. long, minutely pubescent or glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence consisting of clusters of 3–15 flowers at the tips of dwarfed branchlets on the upper part of the stem.
Morphology Reproductive morphology Flowers Pedicel
Pedicels 0·5–1·5 mm. long, minutely pubescent or glabrous, sometimes also with sparse longer glandular hairs.
Morphology Reproductive morphology Inflorescences Bracts
Bracts leaf–like, 1·0–2·0 mm. long, inserted from very near the base of the pedicel to close under the calyx, pubescence as on leaves.
Morphology Reproductive morphology Inflorescences Bracteoles
Bracteoles only present when bract inserted on lower half of pedicel, when present very narrow, linear, 0·5–0·7 mm. long, with marginal hairs that may be either glandular or eglandular and bifurcate and usually also with very short simple hairs.
Morphology Reproductive morphology Flowers Calyx
Calyx segments 4, free to the base, narrowly oblong to narrowly triangular, 0·9–1·5 mm. long, pubescent with marginal hairs that may be either glandular or eglandular and bifurcate, and usually also with short simple hairs on the outer surface, but these absent when there are no such hairs on the leaves.
Morphology Reproductive morphology Flowers Corolla
Corolla 4–lobed, pink to pale lavender to purple, 1·0–3·0 mm. long, 1·0–1·5 mm. broad, the shortest crateriform, the longer ones tubular below and crateriform to campanulate above, the crateriform or campanulate part 1·0–1·5 mm. long, the tubular portion, when c. 1 mm. long or more, usually somewhat curved, corolla lobes rounded, sinuses acute, c. 0·5 mm. deep.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 4, about equalling the corolla, sometimes the anthers protruding; filaments narrow, somewhat expanded below the anthers.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anthers 0·4–0·8 mm. long, deeply divided, thecae elliptical, opening by lateral pores, with appendages sometimes absent, usually present and varying in length from minute to 0·4 mm. long.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary globose, pubescent, with dense white hairs on the upper part and sparser hairs below.
Morphology Reproductive morphology Flowers Gynoecium Style
Style exserted, 1·5–3·0 mm. long, stigma small, capitate.
