of generic names — Bossekia among the rest — of which the au- 

 thors of that nevertheless invaluable treasure of learning had

Even as to the intended meaning of it Rubacer is a failure • 

 for the purpose must have been that of saying in Latin Maple- 

 leaved Easpberry, and what is said is Eed Maple ; for " acer " is

 author himself has placed this beyond dispute, unwittingly to 

 be sure, by giving neuter endings to the trivial names, such as 

 •are always given in Acer but never in Rubus.

B. ODOEATA. Cornut. Canad, under Rubus. 



B. PARViFLORA. Kutt. Gen., " "
