Natal; in the former country ascending to 7000 feet eleva- 

 tion. A very similar, or probably identical species, has been 

 collected by Consul Petherick on the banks of the White Nile, 

 in lat. 7° to 8° N., and the C. serratum, Hochst. of Abyssinia, 

 is probably another variety of it. 



Descr. A shrub, three to five feet high, with scattered 

 angular branches ; which, together with the peduncles, 

 petioles, and leaves beneath, are more or less pubescent. 

 Leaves one and a half to three inches long, opposite or in 

 whorls of three to four, subsessile or shortly petioled, lanceo- 

 late or obovate or oblong-lanceolate, acuminate, more or 

 less deeply obtusely or acutely toothed, rarely quite entire. 

 Cymes fascicled in the axils of the leaves, trichotomous, loose ; 

 branches slender, spreading, with a small leafy bract in the 

 forks, and one or two minute bracteoles at the base of the short 

 pedicel. Calyx-tube globose ; lobes broad, unequal, spreading, 

 ovate, obtuse. Corolla-tube half an inch, pale pink; limb 

 one and a half by one inch broad ; four upper lobes nearly 

 equal, elliptic, obtuse, nearly white ; lower obovate-spathulate,
