LINAGES. 55 



place as the type of a tribe iu the family Liuaccfe, iu the work of 

 general revision published iu 1847-48 by Plauchon.^ He there 

 divided the Liuacere into three sections : Eulinccf^ a large division 

 comprising the three genera lludioln, Linuiu, and RehmanUia^ which 

 he preserved distinct ; ilugoniece., a small group in which are united 

 the thi-ee genera Htigonia, Durandea, and Roucheria (these two last 

 then newly made) ; and Anhadcnicce ., constituted by the simple 

 genus Anisadcnia^ established in 1828 by Wallich and generally 

 until theu placed with the Franlccniacccer' 



In 1862, Benth. and Hook.^ left this family with nearly the same 

 limits, only enlarging it by one new tribe to which the Erytliroxylons 

 give their name '' and which contains with them the two new genera 

 Anculojihm and Ilchcpctaluin. At the same time they separated the 

 old group Hiujoniecc into two tribes, only leaving in one ^ Roucheria ^ 

 with Hugonia, and placing in the other with Ixonanthes^ fi-om 

 which it draws its name,^ Durandea^ and three more genera then 

 almost new and yet incompletely known, Ochtliocosmusl^^ FhjUocos- 

 mus,^^ and Sdvcotheca}'^ In this latter work, the number of genera 

 in Linaceoi was then raised to fourteen. In reviewing them lately, ^^ 

 we had added to the family one more Houniiri,^^ a genus formed 

 by us from all the Humiriaccce ^^ yet known, and which at the 

 fli'st glance seems clearly tUstinguished fi-om the Flaxes, from which 

 it is separated by all other authors. But thanks to the numerous 

 gradation of types which some or other of the Hugonicce represent 

 among them, on one side the Erijthroxglece, and on the other the 

 Ixonanfhca'. connect them so naturally that it is better, we think, to 

 attach the Houmiri to this family than to place them alone. But while
