De Wilclernan and Durand described and figured (I.e. 37, 1. 15) anotber species as. 

 S. Thonneri, which they say was collected together with 6'. mombanzense and sent 

 to them under the same number. They further add that they originally referred it 

 to the same species, but finally separated it on account of the anther-cells of the 

 lower pair of stamens being divergent, instead of parallel, and dehiscing with a short 

 slit. The descriptions and figures of the two species agree, however, to such an 

 extent that I cannot help thinking that the difference in the anthers must be due to 

 some anomaly in their development.
