1. P. senegalense, Spach in Ann. Sc. Nat. Ser. 2. v. 16-t. Shrub ; 

 the branches and young leaves clothed with a pale rusty-brown tomentum, 

 deciduous on the old wood and partially on the upper surface of the leaves, 

 which are opposite or alternate, elliptical or oblong-elliptical, subacute or 

 obtusely apiculate, narrowed or rounded at the base, but not cordate, 2-3^ 

 in, long, 1-1 1 in. broad ; petioles 2-3 lines. Flowers densely tomentose, 

 in axillary and terminal umbellate panicles shorter than the leaves or collected 

 in terminal corymbose panicles a little exceeding the uppermost leaves. To- 

 mentose pedicels equalling or twice as long as the calyx. Stamens 5-8 in 

 each phalange. Ovules solitary, ascending. — Fl. Seneg. t. 23 {exchisive of
