tinguished upon rather fair grounds ; and 2. Homonoia, a well- 

 established genus of 3 or 4 species from East India and the 

 Archipelago. 



Our last group of Acalyphese consists of four genera, in which 

 the male calyx is not so strictly valvate or is already open in 

 the bud. All are from the Malayan archipelago or from 

 Eastern Asia. They are: — 1. Ckeilosa, a single species with the 

 calyx rather deeply divided into slightly imbricate lobes ; 2. En- 

 dospermum, 3 or 4 species with a shortly-toothed calyx, 4-valved 

 anthers, and a peculiar style — including Capellenia, very well 

 described and figured by Teijsmann and Binnendyck in a 

 memoir published many years since in Java, but overlooked by 

 Miquel, and consequently by Mueller as well as by Baillon ; 

 3. CepJialomappa, a single Bornean species, with remarkable capi- 

 tate male flowers, recently described by Baillon; and 4. Clado- 

 ffyne, a single imperfectly known species, which from Spanoghe's 

 description appears to have the capitate male flowers of Cepha- 

 lomappa, but differs from that genus in several particulars. 



There remains Baillon's genus Cocconerion, of two New-Cale- 

 donian species, of which the female flowers alone were seen by 

 him, and the affinity is therefore uncertain. It may belong to 

 Acalyphese ; but the leaves are described as verticillate and the 

 female calyx valvate, a combination otherwise unknown in apeta- 

 lous Crotoneae. 



Subtribe 6. GeloniE-S. Under this name I have collected five 

 or six genera with the very imbricate sepals and usually dense 

 axillary inflorescence so frequent in Phyllantheae, but with the 

 central indefinite stamens and uniovulate ovary-cells of Crotoneae. 

 These genera may not be all nearly connected with each other, 

 but could not well be placed in other subtribes without inter- 

 fering too much with their tribual characters. They are: — 1. 

 Chcetocarpus, a genus originally established for two tropical 

 Asiatic species with globular densely echinate fruits, and well 

 defined by several prominent characters. Since then, however,, 

 two or three tropical American species have been found to agree 

 with them in every thing except the calyx 5-merous instead of 

 4-merous. They have therefore been correctly united with Ohm- 

 tocarpus by Mueller, and proposed by Baillon as a distinct section 

 of that genus under the name of Amanoella. A Guiana plant of 

 Schomburgk's appears to be specifically distinct from the Bra-
