    Leaves coriaceous, 6 – 14  ×  10 – 13 (– 17) cm, (5 –) 7-lobate, the lobe apices subacute to apiculate, margins serrate (to lobulate), teeth (lobule tips) with yellowish glands, upper lamina glabrous, clear or white pustulate, lower lamina glabrous, often with small blackish glands between the vein bases, nerves white-speckled, petioles glabrous and sometimes with white speckles along the base. Tendrils simple
    Probract
    Probracts up to 0.4 cm long, ovoid, acute, glandular on both sides, underneath with few-cellular hairs at 5 – 10× magnification
    Flowers
    Female flowers solitary, pedicel 0.4 – 0.5 cm long, glabrous, the ovary narrow cylindrical, glabrous, receptacle tube c. 0.3 cm long, glabrous, calyx teeth 3 mm long, linear, the corolla 3.2 – 4 cm long and yellow-orange, the lobes 2.5 cm long, obovate, the tips acute-mucronate, the lobes abaxially with several long multi-cellular hairs Male flowers 1 – 2 solitary, pedicel up to 5 cm long, glabrous, receptacle tube glabrous, calyx teeth 0.65 cm long, linear, the corolla 3.7 cm long and brownish yellow, the lobes obovate, the tips acute-mucronate

    Seeds
    Seeds 6.5 – 7  ×  3.5 – 4.5 mm (L/W), symmetrical, ovate in outline, and flat lenticular
    Distribution
    Cocciniasamburuensis is only known from the Samburu District in the Rift Yalley Province in Kenya
    Ecology
    Cocciniasamburuensis grows on rocky outcrops, near rivers or seepage lines, in Acacia-Commiphora deciduous bushland; 1200 – 1600 m.
    Conservation
    The species is only known from four collections, and we therefore cannot assess its conservation status. It is treated here as Data Deficient (DD).
    Vernacular
    None are known.
    Note
    Cocciniasamburuensis was first collected in 1958 and mentioned as Coccinia sp. A in the Flora of Tropical East Africa (Jeffrey 1967: 63), with the characters mentioned being the (5 –) 7-lobate leaves with sinuate-lobulate and glandular-toothed margins and the relatively large flowers. In addition, the species has distinct cylindrical fruits, lineal calyx teeth, and simple tendrils. Jeffrey knew only a male specimen, but female individuals have since become available, and at least five duplicates exist of the type collection (R. B. Faden & A. J. Faden 74/948; R. B. Faden, pers. comm., 7 April 2010). Unfortunately, the whereabouts of three of them remain unclear.
