9. Melodorum, Dun. ; Benth. et Hook. f. Gen. PI. 28. 

 An Asiatic genus, differing from Anona in its free carpels, and from Xylopia in the 

 shape of the petals and the want of the peculiar hollow deciduous anther -bearing 

 portion of the torus. The first of the two following African species does not enter 

 precisely into either of the sections established by Hooker and Thomson, but would 

 constitute a third with glabrous fruits and smooth arillate seeds; the second is still 

 further removed by the want of inner petals and the narrower outer ones, but still may 

 well be included in the genus as far as it is hitherto known.
