have even beeu a distinct family ; but they affect the closest affinity 

 with Drypetes. They have the aspect, foliage, fi-uit, and often the female 

 flower of it ; but their stamens, two or three iu number, free or 

 diadelphous, are inserted at the centre of the flower, and not around

a rudiment of the gyuEeceum; chaa-acters in short which belong, 

 properly speaking, to all the Phyllanthece. The known species are 

 Indian. Luwjetia, Avhich inhabits New Caledonia, is distinguished 

 from the preceding genera by its style branches, instead of occupying 

 the summit of the ovary, being thrown back towards its periphery ; 

 in this respect, it is analogous to Bcrnardia among the uniovulate 

 genera. The first known species had numerous stamens. In a 

 second species they are occasionally nearly definite. In this genus, 

 the presence of a central body is not constant ; but it is sometimes 

 observed. The leaves are opposite. In the species of Bureavia, from 

 the same country, the leaves are also opposite ; the stamens are 

 numerous, the gynoeceum is tri- or tetramerous, with a central style ; 

 and the capsular fruit encloses seeds provided with a laciniate and 

 coloured aril, proceeding at the same time from the micropyle, the 

 hilum, and even the remains of the obturator. The Petalostlgmas^ 

 Australian shrubs, are characterised, not only by the development 

 in fleshy blades of their style branches, but also by the
