The Qenus Bossekia. 



Ifecker was among those early in the field of championship 

 for multitudinous good genera which Linnaeus had of late been 

 so bold as to suppress. He must needs have taken up the case 

 of the Linnaean aggregate Rubus, and in doing this he left in 

 Rubus what for centuries before Linnaeus had constituted the 

 genus, namely the shrubs with compound leaves and clustered 

 flowers. Dalibarda he restored in deference to its simple leaves 

 and monanthous peduncles. He also so defined it as that it might 

 include the still older genus Chammmorus, which, by the way, 

 was not regarded as either a blackberry or raspberry, but as a 

 mulberry, the very name telling us this. 

 Upon the one remaining simple-leaved Linnaean Rubus he sought 

 to establish a new genus, calling it Bossekia (Neck. Elem., ii, 91.) 

 Mr. Eydberg must be credited with having fortified this genus by 

 some new characters, and I for having relieved it of a name so 

 cheap and ill-made as Rubacer, the author of which might have 

 avoided the framing of any new name at all, had he learned, as 

 I have, by long experience, to distrust the Kew Index as to what 

 genera have been published ; for there are, perhaps, «ome scores
