Shrub or small tree 1.5–10 m. tall, with glabrous stems. Leaf-blades elliptic or oblong-elliptic, 7–18 cm. long, 3.5–7(–10) cm. wide, acute, obtuse or slightly acuminate at the apex, cuneate at the base, glabrous above, pubescent beneath on the midnerve and sometimes on the lateral nerves as well, or entirely glabrous beneath save for the hairy domatia; nodules absent; petiole 0.5–3 cm. long, glabrous or pubescent; stipules ovate or ovate-elliptic, 1–2(–? 2.5) cm. long, shortly bifid for 1–2 mm. or ± entire, glabrous save for a few marginal hairs, deciduous. Flowers heterostylous, 5-merous, in much-branched panicles, lowest branches usually 4; peduncles 2–7(–15) cm. long, glabrous or slightly pubescent; secondary branches 0.3–3.5 cm. long, ferruginous pubescent; pedicels ± obsolete or 1–1.5 mm. long in fruit; main bracts lanceolate with sheathing lobed bases, 5 mm. long, ± ciliate; other bracts and bracteoles smaller, ± ferruginous pubescent. Calyx-tube obconic, ± 1 mm. long, glabrous; limb cupuliform, 1–1.5 mm. long, ± glabrous, lobes very short or obsolete, margined with ferruginous hairs. Corolla white or salmon-tinged above in bud, ± white when developed; tube 2.5–5 mm. long; lobes oblong-elliptic, 1.8–4 mm. long, 0.8 mm. wide, thickened at the apices. Stamens with filaments 1.5 mm. long in short-styled flowers and 0.5 mm. long in long-styled flowers. Style 2.5 mm. long in short-styled flowers and 3.5–7 mm. long in long-styled flowers; stigma-lobes 0.5–1 mm. long. Drupes red, with 2 pyrenes, ellipsoid, 6–7 mm. long, 4–5.5 mm. wide; pyrenes semi-ellipsoid, 6 mm. long, 4.5 mm. wide, 2 mm. thick; dorsal face ± 5-grooved.

Notes
I have seen this taxon in the field on several occasions and the stipules are quite definitely not always bifid at the apex, thus breaking down the only character separating this from its allies. Several specimens, e.g. Kabuye 49 (Kenya, S. Nyeri District, Castle Forest Station, 12 Dec. 1966) and Verdcourt, Polhill & Lucas 3037 (Kenya, Naivasha District, South Kinangop, Sasumua Dam pipeline road, 11 Dec. 1960) have much larger leaf-blades than usual, up to 27 × 13 cm. Three specimens from Karamoja District, Mt. Debasien, Jan. 1936, Eggeling 2760!, Oct. 1944, Dale U.408! and Wilson 768A do not seem to differ from P. orophila in any significant characters. Petit has annotated the Wilson sheet P. fractinervata but has not cited it. The calyx is not correct for that species.
