    Melastomataceae, R. and A. Fernandes. Flora Zambesiaca 4. 1978

    Habit
    An annual, biennial or perennial, much-branched, erect herb up to 2 m. tall.
    Branches
    Branches 4-gonous, pale green to dull red, sparsely to densely hirsute with pale spreading bristles up to 7 mm. long, longer at the nodes.
    Leaves
    Leaves opposite, those of the main stem patent or folded along the midrib and reflexed; lamina 1·5–9 x 0·8–2–5 cm., narrowly lanceolate to elliptic-oblong or ovate-lanceolate, rarely ovate, acute at the apex, roundish and contracted at the base, subentire or crenate, subconcolorous (both faces light green) or discolorous (dark- or yellow-green above, lighter beneath), somewhat rigid, sparsely to densely appressed-setose above, subhirsute below, longitudinally 3-S-nerved, the nerves slender, impressed on the upper face, slightly raised on the lower, the transverse nerves and reticulation inconspicuous; petiole 2–10 mm. long, slender, hirsute.
    Flowers
    Flowers 4- or 5-merous, subsessile, in terminal and axillary cymes, those of the main stem often approximate and usually forming congested inflorescences; bracts shorter than the receptacle, brownish, scarious, ciliate, late deciduous.
    Receptacle
    Receptacle 5–7 x 4 mm., cylindric, long whitish- or purplish-hirsute, covered with cylindric, patent or reflexed usually long appendages somewhat dilated and long stellate-setose at the apex or rarely the appendages short and with 1-few bristles at the top.
    Calyx
    Sepals 4–6 x 2–3 mm., oblong, stellate-setose at the apex, ciliate at the margin, caducous; intersepalar segments like the uppermost receptacle-appendages but longer.
    Corolla
    Petals 12–17 x 8–13 mm. long, obovate, pale to light purple.
    Stamens
    Shorter stamens: anthers 5–8 mm. long, pedoconnective c. 1 mm. long with a very short 2-lobed appendage at the base; filaments 6 mm. long. Longer stamens of dissotidoides forms: anthers 7–8 mm. long, pedoconnective 5·5–8·5 mm. long with 2-lobate, 1–2 mm. long appendage at base; filaments c. 8 mm. long. Stamens of osbeckioides forms subequal, those opposite to the sepals with the pedoconnective slightly longer.
    Fruits
    Fructiferous receptacle 8–9 x 5–7 mm., ovoid to urceolate. Capsule shorter than the receptacle, setose at the apex on the valve-margins and with a ring of strong bristles around the style-insertion.

    Melastomataceae, G. E. Wickens. Flora of Tropical East Africa. 1975

    Habit
    Woody perennial herb 0.3–2 m. high; branchlets hispid-pilose to scabrid.
    Leaves
    Leaves subsessile; lamina linear-lanceolate, oblong-lanceolate or oblong-ovate, 1.5–9.5(–11.5) cm. long, 0.5–3 cm. wide, apex acute, base subcuneate, margin slightly serrate and appressed setose, long setose-pilose on both surfaces; midrib and 1–2 pairs of basal longitudinal nerves impressed above, slightly raised beneath.
    Inflorescences
    Inflorescence of dense paniculate clusters; flowers 4–5-merous.
    Calyx
    Calyx-tube (fig. 10/1, 2, p. 31) ovoid-urceolate, 6 mm. long, 4 mm. in diameter, covered with stellate-setose linear or obtriangular capitate appendages, setae sometimes very dense and obscuring the flower; lobes caducous, narrowly triangular, 5 mm. long, margin shortly ciliate, apex with a single stellate-setose scale, otherwise glabrous; intersepalar appendages resembling those of the calyx-tube.
    Corolla
    Petals pinkish to purple, oblong-obovoid, 10–15 mm. long, 8–13 mm. wide, apex truncate or rounded.
    Stamens
    Stamens 8 or 10, markedly unequal or subequal in “ osbeckioid ” forms; large stamens with anthers 7–8 mm. long, free part of connective arcuate, 8.5 mm. long, bilobed appendage 2 mm. long, filament 8 mm. long; short stamens (including all of “ osbeckioid ” forms) with anthers 5–8 mm. long, connective produced 0.5–0.8 mm., bituberculate appendage 0.5 mm. long, filament 6 mm. long.
    Ovary
    Ovary with an apical tuft of setae, concealed by the calyx-tube.
    Fruits
    Fruiting calyx enlarging, mainly by an elongation of the neck, to 7–10 mm. long, 4.5 mm. in diameter; capsule not exserted.
