The third has the inflorescence and flowers of Nauclea, but its ovaria and 
pericarpia are confluent, the whole head forming a compound spherical fleshy 
fruit, which is, I suppose, the country-fig of Sierra Leone, mentioned by 
Professor Afzelius.* ; 
The fourth is a second species of Neurocarpwa, a genus which IT have 
named, but not described, in the catalogue of Abyssinian plants appended to 
Mr. Salt’s Travels.-F 
The fifth genus is intermediate between Rubiaceze and Apocinere. With 
the former it agrees in habit, especially in its interpetiolary stipules; and in 
the insertion and structure of its seeds, which are erect, and have the embryo 
lodged in a horny albumen forming the mass of the nucleus; while it resembles 
Apocinez in having its ovarium entirely distinct from the calyx: its capsule 
in appearance and dehiscence is exactly like that of Bursaria. 
The existence of this genus tends to confirm what I have formerly asserted 
respecting the want of satisfactory distinguishing characters between these two — 
orders, and to prove that they belong to one natural class: the ovarium 
superum approximating it to Apocinee ; the interpetiolary stipules and struc- 
ture of seeds connecting it, as it appears to me, still more intimately with 
Rubiacez. 
The arguments adduced by M. de Jussieu} for excluding Usteria from 
Rubiacez and referring it to Apocinee, are, its haying ovarium superum, an 
irregular corolla, fleshy albumen, and only one stamen; there being no example 
of any reduction in the number of stamma in Rubiacez, (in which Opercularia 
and Pomax are not included by M. de Jussieu,) while one occurs in the male 
flowers of Ophioxylum, a genus belonging to Apocinez. From analogous 
reasoning he at the same time decides in referring Gertnera of Lamarck § to 
Rubiacex, though he admits it to have oyarium superum ; its flowers being 
regular, its albumen more copious and horny, and its embryo erect. But all 
these characters exist in the new genus from Congo. These two genera 
therefore, together with Pagamea of Aublet, Usteria, Geniostoma of Forster 
(which is Anasser of Jussieu) and Logania,4] might, from their mere agree- 
ment in the situation of ovarium, form a tribe intermediate between Rubiacez
