20 PARSONS ON THE ROSE. 



Paris alone. The species is very vigorous, but does not 

 seem to answer well in our hot sun. The change from 

 its native shaded thickets and hedges is too much for 

 its tall, exposed stem^ and, although the stock may not 

 itself die, yet the variety budded upon it will fre- 

 quently perish in two or three years. This is doubt- 

 less partly owing to a want of analogy between the 

 stock and the variety given it for nourishment, but that 

 the former is the prominent evil is evident by the fact 

 that dwarfs of the same stock, where the stem is shaded 

 by the foliage, flourish much better. The Eglantine, in 

 favored situations, is very long-lived. A French writer 

 speaks of one in which he had counted one hundred 

 and twenty concentric layers, thus making its age the 

 same number of years. Another writer speaks of an 

 Eglantine in Lower Saxony, whose trunk separated into 

 two very strong branches, twenty-four feet high, and ex- 

 tending over a space of twenty feet. At the height of 

 seven feet, one of the branches is nearly six inches, and 

 the other four inches, in circumference. There is a tra- 

 dition that it existed in the time of Louis the Pious, 

 King of Germany in the ninth century. This, however, 

 must evidently be received with some allowance. Flow- 

 ers, pink. Fruit, scarlet, obovate or elliptic. A shrub, 

 growing from four feet to six feet in height, and flowering 

 in June and July.
