IV. C MANORS IN NOMENCLATURE. 



[The recent published works of Drs. Gray and Vasey have made necessary many changes 

 in the nomenklatura of our species. It has been suggested that these changes be deferred 

 until the publication of a second edition of the " Flora.'- but this has seemed to be inadvis 

 able, as it must b;- some years before a second edition can be brought out, if ever, and if we 

 are constantly confronted by the old names we shall never become familiar with the new and 

 correct ones.]
