I cannot recognise this from the description, nor does any species 
of Crassula from the neighbourhood of Zwartkops known to me come 
near it. It may be that it should not be placed into Tillaeoideae. 
Unfortunately, the flowers are not described in the following account 
taken from Thunberg, FI. Cap. ed. Schultes, 293.
