Information
Low shrub or small tree 1–6 m. high, flat-crowned. Old bark very dark and rough. Branchlets densely grey-pubescent or -puberulous, often with minute reddish glands, ultimately brown to blackish; bark not peeling. Stipules spinescent, straight, to 6.7 cm. long, never inflated; other prickles absent. Leaves with dull pubescence; petiole 3–8 mm. long; rhachis 5–18.5 cm. long; pinnae of well-developed leaves of mature shoots often 15–41 pairs (reduced leaves with fewer pairs sometimes also present), mostly 1.5–4.5 cm. long; leaflets 1.5–5 mm. long, 0.75–1.5 mm. wide, minutely ciliate, otherwise glabrous to pubescent. Flowers cream (T.T.C.L.: 335), in heads; involucel ¼-¾-way up the pubescent and glandular peduncle. Corolla puberulous outside (glabrous fide Harms), 2–4 times as long as calyx. Pods doubtful.

Notes
Harms (see above reference) described some fragmentary pods that may (there was doubt about it) belong; these were “flat, lanceolate, brownish, smooth and. .. on both margins with a prominent longitudinal ridge”. Greenway 9055! (Tanganyika, Masai District, Subiti) has a single complete valve of a pod. It is coriaceous, though not much thickened, about 14 cm. long and 1.4 cm. wide, flattened, smooth, thickened at margins and densely puberulous and glandular. It is abruptly curved, but this may possibly be abnormal. The comparatively broad rigid-looking leaf-rhachis is a characteristic feature of A. fischeri.
