470 MR. G. BENTHAM ON AFRICAN ANONACEiE. 
Polyalthia, Blume ; Benth. et Hook. f. Gen. PL 25. 
An Asiatic genus, in which we include the Asiatic Guatterias as limited in Hooker 
and Thomson's ' Flora Indica,' and probably, as far as hitherto known, unrepresented in 
Africa. I only mention it here because in the Hookerian herbarium there is a specimen 
of P. {Guatteria) Korinti, with the label " Gimtteria lucida, Boj. ex ins. Mombase oris 
African orientalis, Bojer." There has been, however, probably some misplacement of 
labels— perhaps in the Mauritius Garden ; for the Kew herbarium has another specimen, 
derived from the late Dr. Graham's collection, also as from Bojer, with a similar label, 
which is the Uvaria lucida described above. 
5. Popowia, Endl. ; Benth. et Hook. f. Gen. PI. 25. 
A small genus, not yet sufficiently well known to be accurately characterized, con- 
taining two African, two Asiatic, and one Australian species ; differing from Polyalthia 
m the more connivent petals, from Melodorum in the small flowers rather more open, 
and in the carpels with one or two ovules erect from the base of the cavity, not ventral, 
and from Clathrospennum in the more numerous stamens with the cells lateral, below 
the summit of the connectivum, not bordering the top of the connectivum. In the P. 
caffira, however, the anthers are not so closely packed, nor the cells so much concealed 
by the flattened top, as in the Asiatic and Australian species.
