German blackguardism has deprived us of all the flowering 
material of the species save one small twig with three flowers 
upon which I have rested for identification with the abundant 
fruiting material we have had later from Forrest. “These fruit- 
ing specimens have supplied ample seed from which I hope we 
shall have a good braird of seedlings. They further—by showing 
conspicuously the style glandular to the top upon a glandular 
ovary—suggested affinity with the Thomsoni Series and in the 
Series of Souliei. The seeds are however those rather of the 
Fortunei Series and then there is the heptamery in the flower 
which is unknown in the Thomsoni Series except in Rh. rotundi- 
foltwm—a species which I think should be removed from it, its 
only relation to the Thomsoni Series being the orbicular leaf; 
the flower characters too are distant and perhaps it is one of the 
Fortunei Series also.
