LINAOE^. 55 



place as the type of a tribe in the family Linacese, in the work of 

 general revision published in 1847-48 by Planchon.^ He there 

 divided the Linacese into three sections : Uulinece, a large division 

 comprising the three genera Radtola, Zinum, and Eeinwardtia, which 

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

 the three genera Hugonia, Durandea, and Roucheria (these two last 

 then newly made); and Jnisadeniece, constituted by the simple 

 genus Anisadenia, established in 1828 by Wallich and generally 

 until then placed with the Frankeniacece.^ 



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

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

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

 Aneulophus and Hebepetalum. . At the same time they separated the 

 old group Hugoniece into two tribes, only leaviag in one ^ Roucheria ^ 

 with Hugonia^ and placing ia the other with Ixonanthes^ from 

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

 almost new and yet incompletely known, Ochthocosmus,^" Phyllocos- 

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

 in Linacece was then faised to fourteen. In reviewing them lately, ^^ 

 we had added to the famUy one more Koumiri^^ a genus formed 

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

 first glance seems clearly distinguished from 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 Hugoniece represent 

 among them, on one side the ErythroxyleoB^ and on the other the 

 IxonanthecB, connect them so naturally that it is better, we think, to 

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