Boraginaceae, B. Verdcourt. Flora of Tropical East Africa. 1991

Morphology General Habit
Perennial or less often annual or biennial herb (15–)25–120 cm. tall; stems rough with ± adpressed upwardly directed hairs above but spreading or deflexed beneath, very dense on young parts; usually with a thick woody tap-root.
Morphology Leaves
Radical leaves narrowly ovate, elliptic-oblong, linear-oblong or oblanceolate, 8–21 (–30) cm. long, 1.1–6 cm. wide, subacute at the apex, long-attenuate at the base, rough with rather sparse to dense short adpressed white hairs from conspicuous white cystolith dots, less densely placed on the undersurface; petiole 2–10 cm. long, spreading pubescent; cauline leaves similar, linear-lanceolate to ovate, 1.5–17(–30) cm. long, 0.2–5 cm. wide, subacute to acute at the apex, contracted to or slightly widened at the base, sessile or pseudopetiolate.
Morphology Reproductive morphology Flowers
Flowers in terminal and axillary, simple, dichasial or trifid cymes but not forming densely branched inflorescences; individual cymes short at first but soon 10–25 cm. long; pedicels mostly short, 2–7(–12) mm. long or that of central flower of dichasium up to 1.5 cm.; axes sparsely to densely adpressed pubescent.
Morphology Reproductive morphology Flowers Calyx
Calyx-lobes narrowly ovate to oblong or elliptic-obovate, 1.2–1.5(–3.5) mm. long, 0.4–1.2(–2) mm. wide, enlarging in fruit, 3–4 × 1.5–1.8 mm., acute to ± rounded at the apex, pubescent and ciliate and sometimes with marked cystolith-tubercles.
Morphology Reproductive morphology Flowers Corolla
Corolla blue or pinkish mauve turning bluish, sometimes with yellowish white centre or less often white or white with blue or pink centre; tube 1.5–2(–2.5) mm. long; lobes rounded-oblong, (1.2–)1.5–3 mm. long, 1–3 mm. wide.
Morphology Reproductive morphology Flowers Gynoecium Style
Style (0.3–)0.5–3 mm. long in fruit.
Morphology Reproductive morphology Fruits
Fruit often reddish, 6–9 mm. wide; nutlets compressed ovoid, (2.5–)3.5–4 mm. long, 3–3.5 mm. wide, covered all over with fairly short usually slender glochidia 0.5–1 mm. long and with few short additional tubercles above or with upper face almost or quite devoid of tubercles save for a median line, occasionally with peripheral ones joined at base to form a ± distinct margin but not as marked as in many species of the genus; there are, however, numerous intermediate fruit patterns.

Morphology General Habit
An erect or ascending perennial herb up to 1.2 m. high; stem (or stems) much branched, clothed with somewhat rigid hairs, spreading or retrorse on the lower part, appressed to the upper part as on the branches.
Morphology Leaves
Inferior cauline leaves long-petiolate, up to 25 x 3(5) cm., linear-lanceolate to linear-oblanceolate, sometimes narrowly lanceolate, with a petiolar portion up to 7 cm. long (radical leaves not seen). Cauline leaves at middle stem up to 14.0 x 1.5 cm., narrowly lanceolate to linear-lanceolate, hispid-pilose on both surfaces, acute at apex, acute to obtuse at base; midrib and nerves depressed above, prominent below.
Morphology Reproductive morphology Inflorescences
Cymes usually grouped by two on each peduncle, often with a flower at the fork and arranged in an ample lax panicle.
Morphology Reproductive morphology Flowers Pedicel
Pedicels c. 2 mm. long, elongating up to 7 mm. and much recurved in fruit.
Morphology Reproductive morphology Flowers Calyx
Calyx c. 2 mm. long, shortly hispid outside, ciliate at the margins, devided to near the base; lobes ovate to oblong-elliptic, subacute to rounded at apex, accrescent.
Morphology Reproductive morphology Flowers Corolla
Corolla glabrous, blue; tube 1.5–2.0 mm. long; lobes 1.0–1.5 x 1.0–1.5 mm., circular to oblong, rounded at apex, spreading; fornices c. 0.4 x 0.6 mm., slightly bilobed, papillose.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens inserted about the middle of the corolla tube; anthers c. 0.5 mm. long, elliptic; filaments about as long as the anthers.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Style c. 0.5 mm long; stigma subcapitate.
Morphology Reproductive morphology Fruits
Fruit c. 6 mm. in diam.; nutlets c. 2.5 x 2.0 mm. (without glochids), ovate, slightly marginate, covered all over with glochids.
