Notes
A. nilotica subsp. kraussiana has a wide range of altitude and a considerable range of habitat. As might be expected, it is variable. Forms with numerous pinnae (13-17 pairs) seem most frequent in central Mozambique. The pod also shows considerable variation. It is hard to differentiate concisely in words between subsp. kraussiana and subsp. subalata (Vatke) Brenan, which occurs in East Africa and perhaps also the Sudan, and some specimens of subsp. kraussiana show in certain ways an approach to subsp. subalata. Trapnell 1438 (K), from Zambia, S: Gwembe, fr. iii.1934, has crenate-margined ± moniliform pods 1?2-1?3 cm. wide as in subsp. kraussiana, but they are pubescent all over. Angus 2931 (K), from Zambia, 27 km. E. of Sinazeze, fr. 16.iv.1961, has similar pods but up to 1?5-1?8 cm. wide. Davies 2074 (SRGH), from Rhodesia, N: Mtoko Distr., fr. viii.1956 and Pedro & Pedrógão 6197 (LMJ), from Mozambique, MS: between Munhinga and Dombe, fr. 4.vi.1949, have pods up to 2 cm. wide, but with the characteristic glabrescent bosses over the seeds as in subsp. kraussiana. These will serve to indicate subsp. kraussiana when, as sometimes happens, the margin of the pod is almost as straight as it is in subsp.subalata.
