Status: | Native |
Description: |
A small tree, but reaching 20 m elsewhere, semi-evergreen. Bark smooth. Leaves paripinnate. Flowers in axillary and terminal racemes, appearing with the new foliage. Pods black or dark brown, up to 70 cm long, rigid, snapping into cylindrical sections when pressure is applied, falling when mature. The seeds in individual compartments, surrounded by dry pulp, rattling when the mature pod is shaken. |
Type location: |
Angola |
Notes: | Conservation status: A rare species though widespread, probably overlooked and mistaken for Cassia abbreviata. The well-known trees no longer exist, having made way for road widening (Pemba) or cropping (Chongwe). There are, however, a few trees in cultivation. The key in FZ distinguishes this species from C. abbreviata by “seed not enclosed by pulp.” Whatever the appropriate term for the edible stuff surrounding the seed, it is essentially similar to that of Piliostigma thonningii, the seeds of which are described as “embedded in pulp” (commonly known as 'monkey bread'). The pod of C. angolensis resembles that of P. thonningii in falling when mature, and with the seeds rattling when the pod is shaken. These are typical features of herbivore dispersal. C. abbreviata, which is adapted to bird dispersal, has sticky pulp, and the pods do not fall at maturity. |
