character to consider. Gilg figures and describes the follicles of his S. grandi- 
florus as perfectly smooth. Now, Mrs. Monteiro says in her book “ Delagoa Bay,” 
164, that there are two species of Strophanthus in Delagoa Bay. The follicles of 
one are much sought for, so that “ they disappear most mysteriously when ripe, those 
of another species being left unnoticed,” and in a letter to Sir W. T. Thiselton-Dyer 
she observes that the latter species had rather smaller and rougher follicles. She 
actually sent two kinds of follicles to Kew, one very rough with numerous lenticels, 
the other smooth, like that figured by Gilg on Plate vii. of his monograph. She 
further suggests that the plant raised at Kew and figured in Bot. Mag. t. 7390 (the 
real basis of S. petersianus var. grandiflorus) was the one with the rough follicles. 
Under those circumstances I consider it more expedient—quite apart from the 
question of priority—to use the name S. verrucosus instead of the ambiguous 
S. grandiflorus.
