Engler and Diels in their monograph of the African Anonaceae, 

 have changed the name of Popowia Slannii, Baill., to P. Baillonii, 

 Engl, et Diels, and applied the name P. Mannii, Engl, et Diels, to 

 another species, Glathrospermum Mannii, Oli v., apparently under 

 the impression that O. Mannii was published before P. Mannii, 

 Baill. Adansonia, vol. viii., p. 305, however, shows that Baillon's 

 description was published on May 30th, 1868 ; Oliver's was 

 published in July, 1868 (see Kew Bull, 1905, p, 29). 



It is therefore necessary to rename P. Mannii, Engl, et 

 Diels {Glathrospermum Mannii, Oliv.), and inasmuch as it 

 appears to be the only African species of Popowia with unisexual 

 flowers, the name Popowia diclina, Sprague, seems appropriate. 

 P. diclina is apparently dioecious, for the two sexes have not 

 hitherto been collected together.
