154 NATURAL HISTORY OF PLANTS. 



which, with fourteen genera of EwphorliacecB^ includes the Box, 

 Papayads, and StercnUa. Adanson ' also gives too great extent to his 

 Tlthymalus, in including Clusia, Hernandia, Papaya, Polygala, and 

 Cupania. A. L. JussiEU ~ reduced them a little, but still included 

 the Ciicurbitacece, such as Suchium. Tt was E. Brown who, in 

 1815,^ appears to have first given to this family the name of Eiiplior- 

 hiacece. Some years after, A. de Jussieu published a monograph "^ 

 which seems really very imperfect, but which was followed for a 

 long time by the botanists of that period, until the time when 

 Klotzsch took lip, in several of his works,^ a rapid revision of the 

 Tricoccea of Linn^us, to which he added numerdlis genera, the 

 greater number without much value or which had already been 

 established under other names by former authors. When we under- 

 took, in 1858, a ' General Study of the Gi'oup Euphorbiacece,'' we 

 found nearly two hundred and sixty genera preserved as valuable, 

 and reduced them to close upon two hundred. At the same time 

 we showed, in several successive publications, that the Box does 

 not belong to Euplwrhiacece^ that the families of AntideHmece^ Pu- 

 traujivece^ and 8cepaceie^ are not necesary, although they have been 

 described as distinct, and more or less separated fi'om the EupJior- 

 biacece, and that they ought to be united with them. Eight years later, 

 .1. Mueller (d'Argovie), drawing up for Prodromus,^^' a description 

 of all the known Euphorbiacea, united a good nimiber of genera that 

 we had preserved, divided several others, and enumerated one hundi'ed 

 and ninety one genera, a dozen of which are insufficiently known. 

 Since this publication, J. Mueller proposed, in 1872, the genus 

 Pseudocroton ^' and elevated Adenopliwdra to the rank of a genus ; 

 EAnLKOFFER published the genus Pausandra in 1870, i' and we 

 made known the genus Piranhea in 1865,^^ Eisslliaria of F. Mueller, 

 in 1867,'* and, quite recently, the genera Alphandia, Ramelia, Chori- 

 ceras, Bureavia, Cephalomappa, Cocconerion, and Trisingyne}^
