Habitat: NATAL. Inanda, 1,800 ft. alt., March Wood 480; near Murchison, 

 2,000-2,500 ft. alt. May, Wood 3036; near Eshowe, Zululand, April Wood 7591 ; 

 near Durban, Gueinzius ; Dumisa, Liudatis 314 ; without precise locality, Gerrard

Two species of this genus have already been figured and described in this 

 work, viz., P. saccatus in Vol. 1 , plate 85 ; and P. tomentosus in Vol. 4, plate 3 1 6. 

 The species above described has, as will be seen, a wide range of distribution in 

 South Africa, but it has no special value, except, perhaps, as an ornamental plant.
