Perennial succulent woody herb ( Fig. 3A View FIGURE 3 ); stems much-branched, up to 50 cm long, covered with white powder ( Fig. 3B View FIGURE 3 ). Leaves sessile, alternate, narrowly oblong, 10–40 × 3–8 mm, apex obtuse to acute, base shortly auriculate-peltate, covered with white powder ( Fig. 3B View FIGURE 3 ). Inflorescences of terminal corymbose cymes, many-flowered, up to 10 cm long ( Fig. 3C View FIGURE 3 ); bracts similar to leaves, but smaller ( Fig. 3D View FIGURE 3 ); pedicels 2–10 mm long. Flowers 5-merous ( Fig. 3E View FIGURE 3 ). Calyx-lobes oblong-lanceolate, 5–7 × 1–2 mm, base united for 1 mm, spurs absent or slightly spurred ( Fig. 3D View FIGURE 3 ). Petals bright yellow, lanceolate, 7–11 × 2–3.5 mm, base united, apex obtuse, slightly reflexed in open flowers ( Fig. 3E View FIGURE 3 ). Stamens 10, with antisepalous filaments 3–5.5 mm long; antipetalous filaments inserted 1.3–2 mm above the base of the petals and free for 2–4.5 mm; anthers oval, 0.8–1 mm long ( Fig. 3E View FIGURE 3 ). Nectary scales ca. 0.6–0.8 × 0.6–0.9 mm, shallowlly 2–lobed at the tip. Carpels 5, shortly united at the base, 2–4 × 0.8–1.5 mm; styles ca. 1 mm long ( Fig. 3E View FIGURE 3 ). Seeds numerous, brown to black, oblong to narrowly oblong, 0.5–0.7 mm long ( Fig. 2B & D View FIGURE 2 ).
Etymology: —The specific epithet “ keniense ” is from the name of the country, “ Kenya ”. It also could be interpreted as derived from the name of Mt. Kenya.
Distribution and ecology: — Sedum keniense is only known from Chogoria Waterfall, Mt. Kenya, at an elevation of ca. 3184 m ( Fig. 4 View FIGURE 4 ). The species grows luxuriantly in wet places on the cliff wall close to the waterfall ( Fig. 4C View FIGURE 4 ) and occasionally on trees ( Fig. 4D View FIGURE 4 ).
