Names
ACACIA macrostachya Reichenb. [family LEGUMINOSAE-MIMOSOIDEAE], Benth. in Lond. Journ. Bot. 1842, 511.
Information
Extremities rusty tomentose-pubescent, with scattered occasionally infra-stipular short recurved prickles. Leaf-rachis similarly pubescent with a conspicuous oblong sessile gland near the base, 4–9 in. long; pinnæ in 14–30 pairs; leaflets linear, subfalcate, acute, thinly silky-pubescent at least beneath, in 25–50 pairs, 2–2 1/2 lines long. Stipules ovate or semi-cordate, deciduous. Spikes axillary, usually fascicled, 3–4 in. long, rather lax, sometimes racemose from the axils of reduced leaves towards the extremities. Flowers sessile. Calyx shortly toothed. Petals united nearly throughout, 3–5 times longer than the calyx. Ovary villous, stipitate.
Distribution
Angola Lower Guinea Huilla, Dr. Welwitsch!Senegambia Upper Guinea Sieber!Sierra Leone Upper Guinea Hutton!
Notes
None of the specimens are in fruit. The only worthy difference that I observe between Dr. Welwitsch's and the type specimen is in the more conspicuous subulate pilose bracteoles of the latter, which in very young spikes long before expansion of the flowers are rather conspicuously exserted. The stipes of the ovary also in the Angola plant may be rather longer, and the petals not united quite so far.
