    Type
    Ethiopia, Somali National Regional State, Harerge, 5 km S of Qarsonney, Thulin, Kaariye & Wilhelmi 11183 (holotypus ETH; isotypi K, UPS).
    Habit
    Climbing or trailing plant to 2 m tall or more, with softly woody main stems and slender herbaceous terminal branches, dioecious; stems glabrous except for sparsely pubescent nodes, purplish brown, angular
    Leaves
    Leaves broadly ovate in outline, palmately divided to the base into (3 – ) 5 ± linear lobes, densely scabrid-punctate above with flat whitish hair-bases up to c. 0.5 mm in diam., entire or ± lobulate with ± revolute margin, the central lobe 20 – 85 mm long, 1 – 8 mm wide or slightly wider in lobulate leaves, obtuse to subacute at the apex, the very tip swollen and often with multicellular hairs when young, the lateral lobes shorter, midrib prominent below, sometimes scabrid with sparse broad-based hairs curved towards lobe apex; petiole 4 – 15 mm long, glabrous or almost so
    Tendrils
    Tendrils simple, slender
    Flowers
    Male flowers solitary or in small clusters; pedicel 4 – 20 mm long, glabrous or sparsely hairy when young; hypanthium obconic, glabrous or sparsely hairy, 3 – 4 mm long; lobes narrowly triangular, 1 – 5 mm long, ± recurved, glabrous or almost so, often slightly expanded at tip; corolla yellow or white with green veins, 18 – 25 mm long, the petals united in lower third, acute or acuminate, pubescent outside, the lobes with multicellular hairs inside; stamens 3, inserted at base of tube, filaments connate and forming a central column, glabrous, anthers all 2-thecous, triplicate, coherent into a head Female flowers unknown; fruiting pedicel 5 – 10 mm long
    Fruits
    Fruit fusiform, 4.5 – 5.5 × c. 1.5 cm, first green with elongated white spots, becoming red when ripe and with a red pulp, smooth
    Seeds
    Seeds asymmetrically ovate in outline, 4 – 5 × 2 – 2.5 mm, compressed, whitish
    Distribution
    Cocciniaogadensis is known from the eastern part of the Somali National Regional State (previously Harerge) in Ethiopia and from the adjacent Mudug Region in central Somalia.
    Ecology
    Acacia-Commiphora bushland, often on sand; 300 – 800 m.
    Vernacular
    (All Somali). Dudu (fide Bally 12989), Ilgeel (at type locality), Lehailu (fide Simmons S179), Salodudub (fide Simmons S63).
    Conservation
    This species is known from a fairly wide range, but all collections, except for the type, are 40 years or more old. There is also an ongoing gradual degradation of the bushlands in which it grows, and it should be regarded as Vulnerable (VU D1).
    Note
    Cocciniaogadensis was first collected by James & Thrupp more than 120 years ago, and their material was cited as “Cephalandraquinqueloba, Sch.?” by Oliver (1888). Cephalandraquinqueloba (Thunb.) Schrad., now Cocciniaquinqueloba (Thunb.) Cogn., is a South African species and Oliver´s record was cited as a misidentification under Cocciniaquercifolia Hutch. & E. A. Bruce by Cufodontis (1965). However, this was a mistake as Cocciniaquercifolia had then already correctly been made a synonym of Cephalopentandraecirrhosa (Cogn.) C. Jeffrey (Jeffrey 1962), and this species has certainly nothing to do with Oliver´s “Cephalandraquinqueloba”. The species was later treated in Flora of Somalia as “C. sp. = Hemming 1713” (Jeffrey & Thulin 1993), and in Flora of Ethiopia and Eritrea as “C. sp. = Bally 12989” (Jeffrey 1995). Although female flowers are not yet known, this characteristic species can safely be described as new. C. ogadensis differs markedly from all other species of Coccinia by its leaves that are divided to the base into linear lobes. The lobes are entire in all Ethiopian collections, but in the single collection seen from Somalia they are lobulate. However, occasional plants with lobulate leaves have also been seen in eastern Ethiopia.
