154 NATURAL HISTORY OF PLANTS. 



which, with fourteen genera of EuphorUacea, includes the Box, 

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

 THhymalm, in including Clusia, Rernandm, Papaya, Polygala^ and 

 Cupania. A. L. JussiEtr ^ reduced them a little, but still included 

 the Cucurhitacece, such as SecMum. Tt was E. Beown who, in 

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

 liacees. 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 up, in several of his works,^ a rapid revision of the 

 Tricoccea of Linn-SIUS, to which he added numerous 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 Group Euphorliaceoe^ 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 Euphorliacece^ that the families of Antidesmem^ Pvr- 

 traujivece^ and Bcepaceoe^ are not necesary, although they have been 

 described as distinct, and more or less separated from the Euphor- 

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

 J, MuELLEE (d'Aegovie), drawing up for Prodromus^^ a description 

 of all the known Euphorhiacece, united a good number of genera that 

 we had preserved, divided several others, and enumerated one hundred 

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

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

 Pseudocroton ^^ and elevated Adenophcedra to the rank of a genus ; 

 Eadlkoffee published the genus Pausandra in 1870,^^ and we 

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

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

 ceraSy Bureavta, Cephalomappa, Coeconerion, and Trisingyne}^
