Notes
Exelland Mendonça, C.F.A. 2: 29 (1956), include in synonymy here the Z. jujuba (L.) Gaertn. var. aequilaterifolia Engl. & Gilg (in Warb., Kunene-Sambesi-Exped.: 292 (1903); type: Angola, Huila, between Goudkopje and Kakele, Baum 190 (B,holo. †, BM, E, K, M, Z, iso. !)); this collection seems to be determinable as Z. zeyherana Sond., a species reaching its northern limit in southern Angola and Rhodesia.  A specimen from Ufipa District, Sumbawanga-Mkunde[Nkunde], 29 Nov. 1949 Bullock 1954, has all the earmarks of Z. abyssinica, but is said to represent a shrub to 6 dm. tall forming miniature thickets in grassland. The habit is that of Z. zeyherana Sond. This indicates the need for careful field observation on the relationship of that species to Z. abyssinica.  Occasionally the pubescence of the upper surface of the leaves at least partially persists. The persistent pubescence is usually found in specimens with blunt leaf-blades less than 1.5 times as long as broad, e.g. Kenya, Machakos/Kitui District, Yatta, 56 km. E. of Thika, 11 June 1961, J.G. Williams in E.A.H. 12331; Tanganyika, Ufipa District, Muse-Sumbawanga road, 10 Nov. 1963, Richards 18383, Mbeya District, Igawa, Jan. 1962, Procter 1957, and Kondoa District, Bereku Ridge, 13 Jan. 1928, B.D. Burtt 1060. The two apparently linked characters of persistent pubescence and leaf shape signal similarity to Z. mucronata subsp. rhodesica R.B. Drummond, which, however, has not yet been found in genetically pure state in East Africa, so far as is known.
