“ Harvey, in his ‘ F). Capensis,’ i. p. 128, does not quote and probably had 
not seen Burchell’s n. 271, which was the type specimen of this species. 
Consequently he has described from other forms. On the other hand, 
S. Thunbergiana (vide Rohrb., ‘Monogr.,’ p. 121, n. 76), founded on their 
(Ecklon and Zeyher) n. 253, is obviously identical with Burchell’s 
n. 271,—the last name, S. Thunbergiana, must therefore be suppressed. 
The forms hitherto commonly marked in herbaria §. Burchellii, Otth 
(see Burchell’s nos. 580, 1254, 6789), and those of many recent collectors, 
must, I nk, be regarded as a mere variety, with more erect habit, and 
generally tendency to narrower leaves—n. 271 being the maritime form, 
with broader leaves (see Gerrard’s n. 605 from Natal), these forms are 
connected by intermediate states, but I can find no differences whatever in 
the calyx-teeth or fruit. Under these varieties and under various names 
(including 8. chirensis and S. sericea of A. Rich., ‘Tent. Fl. Abyssin.’), this
