164 Duration of Races of Plants. 



tude of Boston, where it is nearly or quite killed to the ground, 

 unless in very high and dry situations. This shows that we 

 cannot always judge of the hardiness of a tree from its native 

 climate ; and actual experiments only afford the test in many 

 instances. Thus, for many years, the tree pseony, a native of 

 China, was cultivated as a greenhouse plant, and considered 

 quite tender, until plants accidentally left exposed, were found 

 to be quite hardy. This should lead every nurseryman to 

 attempt the acclimization of various trees, shrubs and plants, 

 judging more by their growth, habit, and other appearances, 

 than by the climate from whence they may have been intro- 

 duced. 



Messrs. Austin cultivate a good collection of herbaceous 

 plants. And we here saw in fine bloom, Anemone vitifolia, 

 Pentstemon Murrayd/mm and Scabiosa canariensis, all showy 

 and desirable. We here saw also, one of the finest stocks of 

 calceolarias, planted out in the open gromid ; many of them 

 being superbly banded, spotted and clouded, with purple and 

 maroon, on cream and yellow grounds.

Art. II. SoTne Remarks on the Duration of Races of Plants. 

 By A. H. Ernst, Cincinnati, Ohio. 



Do races of plants wear out? 



This is a subject attracting just now much attention and 

 discussion among horticulturalists, and which it is to be re- 

 gretted, is not always conducted in a becoming spirit. A 

 subject on which some of the most intelligent seem to differ 

 widely^ should secure at least, common courtesy ; ostentation 

 and haughty bearing are but feeble arguments, and will not 

 weigh much with the well informed, however high or scien- 

 tifikc the source from whence they emanate. 



To my mind, there is rather a misapplication of terms, than 

 a difference on matter of fact. On the one hand, it is held, 

 with no small amount of plausibility, that " varieties of fruit 

 do run out," on the other hand, it is insisted that it is con-
