    Type
    Type: Ethiopia, Semien, Ghaba, Steudner 931 (B†, lecto.) (chosen by Haines & Lye)
    Habit
    Tufted rhizomatous perennial 0.4–1 m tall with stiff stems
    Leaves
    Leaf-blades 5–30 cm long, 3–12 mm wide, flat, scabrid on margins and midrib
    Inflorescences
    Inflorescence ± of several narrow dense often pendulous panicles, 1–2 from each of the uppermost leaf sheaths. Spikes brown, lanceolate, 6–15 mm long, 1–2 mm wide, bisexual, male above and a few female flowers below
    Glume
    Glumes red-brown with paler midrib, 3–6 mm long (the upper always 5–6 mm)
    Fruits
    Utricle red-brown to dark brown sometimes with green ridges, lanceolate, 5–6(–7) mm long (including 2 mm long beak), pubescent or densely scabrid at least on beak and major ribs or ± glabrous save for marginal or scattered scabrid hairs; beak with short erect teeth.
    Ecology
    Streamsides in montane grassland, montane bushland, forest edges, rock crevices, bamboo zone; 2300–3050 m
    Note
    I have taken a broad view of this species which probably will not be accepted in South Africa. The Cherangani Hills material with narrow lanceolate 7 mm long densely pubescent utricles undoubtedly agrees with typical Ethiopian C. steudneri and the lectotype of C. zuluensis also has similarly pubescent slightly shorter utricles (which are not like Gordon-Gray’s figure). However much of the material from S Tanzania has smaller 5–6 mm long utricles which are glabrous save for a few scabrid hairs on the margins of the beak or scattered elsewhere. Richards 7705 (Tanzania, Njombe District, Kipengere Mts, Mtorwi Peak, 12 Jan. 1952 was annotated by Kukkonen in 1984 as C. zuluensis. A number of these T 7 specimens has been named C. zuluensis var. glaberrima Kük. but I have not traced this name. The name zuluensis was published too late to be included in Kükenthal’s monograph. Haines and Lye do not mention C. zuluensis but record C. steudneri from S Tanzania. The T 4 material cited has small utricles 4 mm long and very few scabrid hairs. All the material however has the same habit and general appearance.
