194 NATURAL HISTORY OF PLAINTS. 



teria' (Mudiigasear) and Anomiantkus- (Java). In all other respects 

 their flowers and fruits present so exactly the structure of Uvaria, 

 tliat we cannot remove them into distinct genera. As a section, 

 we might strictly distinguish Marenieria by the arrangement of the 

 flowers, which are borne on a long terminal peduncle ; but we have 

 liardly any similar character to give a clear distinction between 

 Anomhmtlius and those true Uvarias in which the interior corolla 

 is a little the longer. In both types the imbrication of the petals is 

 well marked, and the calyx is gamosepalous, forming a sac with three 

 obtuse teeth in Maroiteriaf and more deeply divided in Anomiaiithis. 

 The flowers of the latter are nearly sessile, while in Marenteria they 

 are, as we have said, on a long peduncle. 



EUipeict' is easily distinguished from the other Uvarias by its 

 ovules being solitary instead of indefinite ; or there are more rarely 

 two in each carpel. They are inserted at a variable height on the 

 inner angle of the ovary, and are somewhat ascending. This 

 character, which at first sight appears very significant, is, however, 

 insufficient to establish a distinct genus in the order AnonacecB ; for it 

 has been shown' that many other genera that are perfectly natural and 

 accepted by all authors as such, include species with uni- or bi-ovulate 

 ovaries, as well as species with many-seeded fruits. Everything else 

 in the three species from the Indian Archipelago which have been 

 described in this genus," being like the characters of Uvaria — the 

 imbricate corolla, the numerous stamens, with the connectives 

 dilated and truncated above the anther-cells, the alternate hairy 

 leaves, the sarmentose stems — we can only retain Elli^eia as a 

 section of Uvaria; with one-seeded fruits.''
