8. A SKan, 
The genus Thorncroftia, of which the species now 
figured is the only one at present, is a native of the 
Transvaal, where it was collected at Barberton by Mr. 
J. N. Thorncroft, growing among rocks at an elevation 
of 4000 feet, in 1911. When describing the genus Mr. 
N. E. Brown expressed the opinion that 7. longiflora in 
general appearance resembles Syncolostemon densiflorus, 
Benth., so closely that when not in flower the two might 
possibly be mistaken. When in blossom, however, the 
two are very easily distinguished since in Thorncroftia 
OcropeR-DEcEMBER, 1919.
