Galpini, Hook. f., at t. 7230; S. Wendlandii, Dammann, 
at t. 7447; and S. Mahoni, Hook. f., at t. 7857. The 
material for our plate has been derived from a 
plant presented to Kew by Mr. R. I. Lynch, Botanic 
Garden, Cambridge, in 1914, This plant was raised 
by Mr. Lynch from seed communicated by Mr. W. E. 
Ledger, Wimbledon, who had received it from South 
Africa, where it had been collected by Mr. J. N. Thorn- 
croft on one of the mountains near Barberton, in the 
Transvaal. It has thriven well under the conditions 
suitable for other species of the genus, and has ripened 
seeds from which a second generation of plants has been 
raised. Crosses, Mr. Lynch informs us, have been made 
between S. denticulata and various species, more especially 
S. cyaneus, 8. Moore, with which it seems to pair more 
readily than with others. In the case of S. cyaneus, Crosses 
have been made both ways, and in each the influence of 
the female parent has shown itself the stronger.
