32 Mr. Brown’s Account of a new Genus of Plants, 
Until these points are ascertained, and the seeds have been 
examined, the question of the affinities of the genus will proba¬ 
bly remain undetermined. In the mean time it may be remarked, 
that as far as the structure of the fruit of Raffiesia is yet under¬ 
stood, it may be considered as in some degree confirming the pro¬ 
posed association of the genus with Azarina ; especially with Cy- 
iinus , in which the ovarium is unilocular, with numerous parietal 
placentae extending nearly to the centre of the cavity, and having 
their surfaces covered with minute ovula. 
From the appearance of the ripe fruit of Aphyteia , a similar 
structure may be supposed to exist also in that genus, of which, 
however, the unimpregnated ovarium has not been examined. 
But these two genera are parasitic on roots, and have also their 
stigmata remarkably developed; and although Raffiesia probably 
differs from both of them in having a superior ovarium, I have 
endeavoured to show that this difference alone would not form an 
insuperable objection to their affinity.
