fasciculate inflorescence, and allied in some respects to Bernardia, 

 but without the anthers characteristic of that genus. One species, 

 however, Ricinella myrcicefolia, Muell. Arg., must be removed to 

 Bernardia, of which it has all the characters, and is indeed nearly 

 allied to B. Gardneri, Muell. Arg. 2. Leucocroton, 2 or 3 Cuban 

 species, quite distinct in habit and character. 3. Chloradenia, a 

 single Javan species united by Mueller with Cephalocroton, pro- 

 bably on account of the inflexion of the apex of the filaments ; 

 but this inflexion is not double as in CepJialocroton, and the in- 

 florescence, styles, and other characters are much nearer those 

 of Alchornea ; the second supposed species of Chloradenia, founded 

 on the imperfectly known Adiscus albicans of Blume, must be a 

 very different plant, which Zollinger was probably right in re- 

 ferring to Croton. 4. Coelodepas, 3 tropical Asiatic species, rather 

 different from each other in habit, but well characterized by the 

 peculiar stamens. 5. Bocquillonia, a JNew-Caledonian genus of 

 5 or 6 species, differing from Alchornea chiefly in inflorescence, 

 but also in the styles. 6. Adenoplicedra, a single Brazilian species, 

 only known to me by Mueller's figure aud description, which 

 indicate a close connexion with Alchornea. 7. Caryodendron, 

 Karst., in w r hich Mueller has since recognized his Centrodiscus as 

 a congener, thus forming two tropical American species evidently 

 allied to Alchornea — but with the stamens inserted round a broad 

 central disk, and the fruit large with hard thick endocarp, repre- 

 sented in the plate rather as opening in valves than separating 

 into cocci. 8. Alchornea, a genus of which Mueller enumerates 

 35 species, distributed into ten sections. Of these, Eualchornea, 

 with 17 American and 1 African species, Aparithmium, 1 

 American species, Cladodes and Stipellaria of five species each, 

 all from the Old World, and Lautembergia and Orfilea, each of 

 one Madagascar species, appear to be well established as sections 

 of one genus. The Australian Coelebogyne, which, following 

 Mueller, I had in the ' Flora Australiensis ' adopted as a section 

 of Alchornea, differs so much in the female calyx and style that it 

 might have been retained as a distinct genus. Baillon's Wetria, 

 2 species from the Malayan archipelago, and Palissya, 1 species 

 from Madagascar, both with numerous stamens, reduced to sec- 

 tions by Mueller, will probably, when better known, be restored 

 as independent genera as originally proposed. The section Si- 

 dalchornea, Muell. Arg., a single Brazilian species, proves to be 

 identical with the species since published by Mueller as A. pyc-
