Names
HYPARRHENIA anamesa W.D. Clayton [family POACEAE], in K.B., Addit. Ser. 2: 85 (1969). Type: Kenya, Masai District, Olodungoro, Glover, Gwynne, Samuel and Tucker 2145 (K, holo.!, EA, iso.)
Information
Densely caespitose perennial, the basal sheaths glabrous or sometimes loosely hirsute; culms 60–120 cm. high. Leaf-blades up to 40 cm. long and 4 mm. wide, but often much shorter, harsh, glaucous. False panicle 15–45 cm. long, loose; spatheoles linear, 4–6 cm. long, the peduncles usually longer; racemes 1.5–2.5 cm. long, 4–6(–7)-awned per pair, white villous, not deflexed; raceme-bases very unequal, the upper 3.5–6 mm. long, glabrous or sometimes softly hirsute. Homogamous pairs 1 or 2 at the base of the lower raceme, and 2 at the base of the upper. Sessile spikelet 5–6.5 mm. long, white villous; callus 1–1.8 mm. long, acute; awn 2.5–4 cm. long, pubescent with hairs 0.1–0.6 mm. long. Pedicelled spikelet white villous, muticous or occasionally with an awn-point 1–2 mm. long. Fig. 184.
Range
DISTR. K1–4, 6; T2, 4, 5, 7, 8 eastern Africa from Sudan to the Cape
Altitude range
100–2500 m.

Notes
H. anamesa links the primarily Mediterranean H. hirta to the tropical H. filipendula (Clayton in K.B. 30: 568 (1975)). It is not usually difficult to distinguish from the latter, which has longer awn-hairs. It is less sharply separated from H. hirta, the 2 homogamous pairs of the upper raceme and the fewer awns per raceme pair being the most reliable characters.
