No. 6853, from the sandy banks ofthe river Bero, in Mossamedes, is a very dwarf 
form, only 2 inches high ; possibly it bears the same relation to the normal form that C. 
microlepis, Bak., bears to C. Iria, L. (C. B. Clarke, in Journ. Linn. Soc. xx. p. 291); that 
is, that the plant was developed from a seed which germinates late in the season shortly 
before the approach of winter. It was collected in July.
