    Type
    Type: Ethiopia, Simien, Enchetcap, Schimper II 576 (P, holo.; BM, K!, S, UPS, iso.)
    Habit
    Perennial herb with tufts 15–45 cm tall from a mostly long-creeping rhizome, usually well spaced and ± slender
    Leaves
    Leaves up to 35 cm, 2–8 mm wide with ± rough margins and midrib near the apex; basal sheaths brownish
    Inflorescences
    Inflorescences green and brown narrow panicles, 2–5 cm long, 1–1.5 cm wide, upper branches with solitary spikelets densely set, 2–5 lower branches with 2–10 spikelets each; main inflorescence bracts 0.6–1 cm long or up to 4 cm when long awned spikelets ovoid, 5–10 mm long, 3–10 mm wide, usually with female flowers below and male above.
    Glume
    Glumes pale brown with pale midrib 3 mm long
    Fruits
    Utricle usually projecting beyond the glume 3.6–4 mm long, including the 1–2 mm long ± curved scabrid beak with 2–3(–5) indistinct ribs on the convex side
    Figures
    Fig. 64, p427
    Ecology
    Swamps, bogs, streamsides and moist ground in bamboo, Hagenia, Hypericum and Erica zones, moorland and upland forest, grassland with Acacia; 2250–3650(–?3750**) m (Note: Mwangangi 364 from Kenya, Mt Elgon give 12500’ but the habitat is given as under the shade of Podocarpus plantation which makes the altitude suspect.)
    Note
    I have not kept up var. leptosaccus. Although there is undoubtedly a difference in beaklength, short in the type of C. conferta and distinctly longer in C. leptosaccus, a careful examination of all the material from Ethiopia and East Africa shows that it would be difficult to decide the name to be given to many specimens. Other characters of the beaks also vary such as marginal scabridity and curvature. Hedberg (A.V.P.: 58 (1957)), mentions Kükenthal’s 1925 paper but does not follow it, citing all material as C. conferta. Haines & Lye cite and figure Purseglove 2971 (Uganda, Kigezi district, Mt Mgahinga, June, 1949) as var. conferta but the specimen and their figure have the long beak of var. leptosaccus; they also record it from E Congo-Kinshasa whereas Robyns and Tournay call the material var. leptosaccus. Out of all the East African material I have examined only the three specimens below are truly var. conferta: Friis & Hansen 2572 (Trans Nzoia District: 5 km above Kimilili Forest Station, 23 Apr. 1975); Hepper et al. 4868 (Mt Kenya, 3100 m without precise locality, 5 Apr. 1975) and Maas-Geesteranus 5471 (cited above).
