Tessmannia Harms

Genus

Angiosperms > Fabales > Fabaceae

Characteristics

Unarmed evergreen trees. Leaves simply pinnate; leaflets alternate, rarely opposite, usually emarginate at apex, marked with numerous pellucid gland-dots (which are visible at least before the leaflets have thickened with maturity), without any marginal swelling near base. Inflorescences of terminal or axillary racemes or panicles. Flowers hermaphrodite, distichously arranged along the inflorescence-axes; bracteoles small, not enclosing the flower-buds, soon falling off. Sepals 4 (? rarely 5), very narrowly imbricate, almost valvate, fulvous-tomentose inside. Petals 5, subequal or one somewhat narrower than the rest, imbricate, clawed, with a crinkled lamina. Stamens 10; filaments tomentose below, one of them free, the rest connate below into a short sulcate tube; anthers dorsifixed, dehiscing by longitudinal slits. Ovary stipitate, usually tomentose but sometimes only so on the stipe; ovules several to numerous; style elongate, coiled when young, with a capitate stigma. Pods flattened, woody, indehiscent (or ? ultimately dehiscent into two valves), short, warted or smooth outside. Seeds 1–4, black or brown, exareolate, with a small basal aril.
