 NEW AFHICAN PLANTS. 53 Hook. Ic. t. 1350). Keel about 2 lines long, with very short claws, acute. Ovary sessile. Legume pubescent, about 3| lines long and 2 lines broad, 7-seeded. Allied to Crotalaria Grantiana Harv., but this has thread-like peduncles about 1 in. long. Crotalaria trifoliolata Baker fil., sp. n. Suffrutex, caulis erectus elatus ramosus ferrugineo-tomentosus. Folia trifoliolata foliola late obovata utrinque tomentosa, IJ ad fere 2 poll, longa, 1-1^ poll, lata, basi cuneata, apice obtusa brevissime petiolulata. Petioli 1-11 poll, longi, dense ferrugineo-tomentosi. Stipulge lineari-lanceolatas. Flores inter mediocres generis in racemos dispositi, apices versus congest! et subsessiles inferne dissiti et bre- vissime pedunculati, racemis terminalibus et axillaribus. Bracteae lanceolatae, 1^-2^ lin. longae tomentosae persistentes. Calyx ex- terne dense ferrugineo-tomentosus, 3-3|- lin. longus. Vexillum late obovatum, carinas a3quilongum. Carina navicularis acuta. Legumen ignotum. Hab. G-alla Highlands, Walenso, T)r. Donaldson Smith, No. 213. Stem erect, branching, evidently several feet high, covered with a dense ferruginous tomentum. Leaves trifoliolate ; leaflets broadly obovate, more or less covered with white hairs on both surfaces ; midrib below sometimes covered with ferruginous tomentum. Petioles in the specimens before me are nearly all erect and closely adpressed to the stem, 1-1^ in. long, perhaps sometimes a little longer. Flowers racemose, towards the apex densely congested. Buds covered externally with a ferruginous tomentum. Bracts lanceolate, about 1-^-2^ lines long. Sepals triangular or lanceo- late, acuminate. Standard about 5 lines long, broadly obovate, with a claw about 1 line long. Standard and keel about of the same length. Keel boat-shaped, with a short claw. Legume not seen. Allied to Crotalaria incana L. and C. Dejlersii Schwf., from Hodgela, Arabia, collected at an altitude of 650 metres. The stem and petioles of the Somaliland plant are covered with a ferru- ginous tomentum, while in C. Dejierdi they are cinereous. Donaldsonia Baker fil., gen. nov. (Plate 355, fig. 1).
