 Natural Order, BbenacBjE. 



An erect much branched shrub, occasionally reaching to 1 5 feet in height. 

 Root black, hard, and tough. Bark of branches reddish-brown, densely silky- 

 pubescent, sometimes glabrescent. Leaves alternate, exstipulate, petiolate, obo- 

 vate or oblanceolate, entire, obtuse or submucronate at apex, tapering at base to a

 Flowers yellow. Peduncles axillary, solitary, 1 -flowered, 4-5 lines long, bibracteate, 

 one bract a little below the calyx, the other above middle of pedicel, bracts linear, 

 2-3 lines long. Calyx 5-parted nearly to base, lobes acuminate, j^-2 lines long, 

 silky, accrescent in fruit. Corolla gamopetalous, 5-lobed, 8-4 lines long, tube 

 short, green and inflated at base, yellow above, lobes oblong, acute, recurved, 

 twisted to the left. Stamens 10, at base of corolla tube in one row, erect, densely

Habitat: Natal: All over the Colony. Inanda, 1,800 feet alt., Wood No. 

 214; near Durban, 100 feet alt., September, Wood. Also in Cape Colony and 

 Tropical i^frica. 



Drawn and described from the Durban specimens. 



Of this genus we have in Natal 5 or 6 species, one of which R. villosa is 

 figured and described in this work, Plate 201 . The above described species has 

 no useful properties so far as known to us, but its tough black roots have pro- 

 bably been the cause of more breakage to ploughs and gear than those of any 

 othi r plant we have.
