Information
Shrub or tree 3.5–10 m. tall, with glabrous branches. Leaf-blades elliptic to broadly elliptic, 6–15 cm. long, 3–9 cm. wide, ± rounded to shortly acuminate at the apex, cuneate at the base, glabrous on both surfaces, thinly coriaceous, without nodules but with domatia; petiole 1–5 cm. long, glabrous; stipules ovate-triangular, 5 mm. long, shortly acuminate at the apex, glabrous, deciduous. Flowers probably heterostylous, 5-merous, in much-branched panicles, 3–7 cm. long; peduncle 1–3 cm. long, glabrous; secondary branches 0.5–3 cm. long, with tufts of ferruginous hairs at junctions; pedicels thick, 1–2 mm. or up to 1 cm. long in fruit, glabrous; bracts and bracteoles small. Calyx-tube subglobose, 1.5 mm. long; limb campanulate, 3–4 mm. long, glabrous, the margin irregularly lobed or almost truncate, the lobes 1 mm. long, minutely ciliate. Corolla white or cream, usually densely minutely papillate outside when dry but smooth in life; tube funnel-shaped, ± 4–5 mm. long, glabrous inside; lobes thick, 6 mm. long, 2.5 mm. wide, inflexed at the apex. Stamens with filaments 3–4 mm. long in short-styled flowers, 0.5–1 mm. long in long-styled flowers. Style 2 mm. long in short-styled flowers, 7.5–9 mm. long in long-styled flowers; stigma-lobes 1 mm. long. Drupes greenish blue, with 2 pyrenes, subglobose, 8 mm. in diameter, glabrous, crowned with the ± conspicuous calyx, not grooved; pyrenes semi-globose, 5–6.5 mm. long and wide, 2.8 mm. thick, the ventral surface plane, the dorsal surface entire. Seeds similar in size and shape, ventral surface plane, the dorsal surface not ribbed; albumen ruminate on both sides.
Range
DISTR. K7 not known elsewhere
Altitude range
30–1850 m. (see note)
Distribution
KENYA Teita District Teita Hills, 8 km. NNE. of Ngerenyi, Ngangao, 10 Apr. 1971, Faden et al. 21/258! & Mbololo Hill, July 1937, Dale in F.D. 3814 in part!KENYA Lamu District Witu, Utwani Forest, Oct. 1937, Dale in F.D. 3831!
Notes
Petit gives the altitudinal range as 1320–1850 m. but he cites Dale in F.D. 3831 from the Utwani Forest which can be no more than 100 ft. This is a curious distribution but I see no reason to suspect the labels.
