CLASS V. 

 PENTANDRIA. 



' " In the train of Spring, arrive 

 Sweet flowers ; what living eye hath viewed 

 Their myriads ? endlessly renewed, 

 Wherever strikes the sun's glad ray ; 

 Where'er the joyous waters stray ; 

 Wherever sportive zephyrs bend 

 Their course, or genial showers descend !"
