An Asiatic genus, differing from Anona in its free carpels, and from Xflopia in tin- 
shape of the petals and the want of the peculiar hollow deciduous anther-b^nng 
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, hut still may 
well be included in the genus as far as it is hitherto known.
