Coast R&GIoN: near Verloren Valley in Piquetberg Div. and on mountains 
near Compagnies Post {East India Company's Fort?) at Saldahna Bay in 
Malmesbury Div., Thunberg! Var. 8; Clanwilliam Div.-; near Lamberts Bay, 
Pillans 86! Malmesbury Div.; among shrubs in sandy places near Hopefield, 
200 ft., only one plant found, Bolus, 10729! 
Possibly Zeyher, 1146, without locality, may belong to this species, but the 
specimens I have seen are flowerless. The variety alba is partly described from a 
fresh flower preserved in fluid and may not differ from the type in anything but 
colour, as the flowers of Thunberg’s type may have originally been as large as 
those of the variety, but have become greatly shrunken from being less carefull « 
pressed.

Of this species I have only seen a small piece of stem less than 1 in, long with 
follicles attached and a few loose flowers dried and in alcohol.
