COMMON EOCK ROSE. 



Helianthemitm vulgare. Nat. Ord., 

 Cistacece. 



HAUCER, in one of his poems, 

 dwells lovingly on the bright 

 little daisy unfolding its flowers 

 to the vivifying rays of the 

 sun, calling it the "Day's- 

 eye ; " and the subject of our 

 present illustration presents us 

 with another striking example 

 of the great law that connects 

 the well-being of the com- 

 monest flowers with the glorious 

 sunlight. So markedly does 

 the rock rose open its petals, 

 and display its beauties to the 

 genial light and wai-mth, that 

 it was by many of the older 

 writers called par excellence the 

 sun -flower; and we see the 

 same idea conveyed in the name 

 that science, in the person of M. Tournefort, has bestowed 

 on it, Helianthemum, a word compounded from the two 

 Greek words signifying " sun " and " flower." It has, of 

 course, no relationship with the sun-flower of the garden.
