Range
Not known from elsewhere
Distribution
Zimbabwe S Beitbridge, 9·6 km. ENE. of Tuli Police Camp, 23.iii.1959, Drummond 5966 (BM; K; SRGH).Zimbabwe E Melsetter, 1220-1830 m., iv.1907, Swynnerton 1603 (BM; SRGH).Zimbabwe C Gatooma, c. 1142 m., 20.iii.1930, Brain 951 (K; SRGH).Zimbabwe W Wankie Distr., opposite Kazungula, 910 m., iv.1955, Davies 1058 (K; LISC; SRGH).Malawi N Karonga Distr., iii.1954, Jackson 1257 (K).Zimbabwe N Bindura, Leaopard’s Vlei, 27.iii.1948, Rattray 1482 (K; SRGH).Zambia S Mapanza N., 1070 m., 9.iv.1955, Robinson 1222 (K; SRGH).Botswana N Okavanga, Nokaneng, Taokhe flood plain, 21.iii.1961, Vesey-FitzGerald 3315 (BM; SRGH).
Notes
With glabrous lemmas.Botswana. SE: 24·8 km. N. of Mahalapye, 15.iv.1931, Pole Evans 3205 (SRGH).Zambia. S: Mazabuka, v.1932, Trapnell 1070 (SRGH). Rhodesia. W: Wankie, c. 900 m., 11.iii.1929, Pardy 4934 (SRGH).Examination of the holotype of A. filiformis Henrard (Pardy 4934) shows that it represents a slender plant which agrees very well, in nearly all panicle and spikelet characters, with subsp. borumensis except for the lemmas which are glabrous. The presence or absence of the scabridity on the lemmas is not of great taxonomic importance since the forms with glabrous lemmas are met with also in the other subsp. As this feature is not accompanied with any other essential diagnostic characters, these forms are not treated here as separate taxa. The absence of long hairs on leaf-sheaths is also not an important character, because the forms with scabrid lemmas, also do not always possess such hairs.In its very lax panicle with branches bearing a few spikelets at the ends, subsp. borumensis resembles A. bipartita, from which it could be distinguished mainly by having a superior glume longer than the inferior and by the scabridity or pubescence of the glumes. The lemma of A. scabrivalvis subsp. borumensis is usually coarsely scabrid towards the apex, while in A. bipartita it is glabrous and smooth.
