and Apocinex. This tribe, however, would not be strictly natural, and from 
analogy with the primary divisions admitted in Rubiaceae, as well as from 
habit, would require subdivision into at least four sections: but hence it may 
be concluded that the only combining character of these sections, namely, ovarium 
superum, is here of not more than generic value: and it must be admitted also 
that the existence or absence of stipules is in Logania * of still less importance. 
APOCINE. There are only six plants in the collection belonging to 
this order: 
The first of these, together with some other species from Sierra Leone, 
constitutes an unpublished genus, the fruit of which externally resembles that 
of Cerbera, but essentially differs from it in its imternal structure, being 
polyspermous. The Cream fruit of Sierra Leone mentioned by Professor 
Afzelius,t probably belongs to this genus, of which an idea may be formed by 
stating its flower to resemble that of Vahea, figured, but not described by M. 
Lamarck,+ and its fruit, that of Voacanga§ of M. du Petit Thouars, from 
which bird lime is obtained in Madagascar, or of Urceola|| of Dr. Roxburgh, 
the genus that produces the caoutchouc of Sumatra. 
The second belongs to a genus discovered at Sierra Leone by Professor 
Afzelius, who has not yet described it, but has named it Anthocleista. This 
genus, however, differs from Potalia of Aublet (the Nicandra of Schreber) 
solely in having a four celled berry; that of Potalia being described both by 
Aublet and Schreber as trilocular, though according to my own observations 
it is bilocular. M. de Jussieu has appended Potalia to his Gentianeex, 
partly determined, perhaps, from its being described as herbaceous. The 
species of Anthocleista from Congo, however, according to the account given 
me by Mr. Lockhart, the gardener of the expedition, is a tree of considerable 
size, and its place in the natural method is evidently near Fagrea. 
Whether these genera should be united with Apocinez, or only placed near 
them, forming a fifth section of the intermediate tribe already proposed, is 
somewhat doubtful. 
In the perfect hermaphrodite flowers of Apocineze, no exception occurs either
