its fine double white flowers in ample corymbs, on erect 

 stems two or three feet high, have the appearance of snow. 

 From June to August. Leaves pinnate, downy beneath ; 

 the terminal leaflets larger, three-lobed ; the lateral ones 

 undivided. This and most of the species succeed best in 

 a strong, most soil, enduring the severest winter without 

 protection. 



The Golden-striped leaved Meadow-sweet is a variety 

 of the single Meadow-sweet, with leaves elegantly vari- 

 egated with golden-yellow. The flowers, which are not of 

 much account, are of a greenish-white. 



S. filipendula* — Dropwort, is an herbaceous perennial 

 of easiest culture. It is so called from the manner in 

 which its tuberous roots hang together by threads. The 

 flowers are arranged in corymbs, somewhat flattened. It 

 is very handsome in bud, just before blooming; the buds 

 are bright rose or red. The foliage is elegant ; leaves pin- 

 nated ; leaflets serrated. The Double Dropwort, S. JiU- 

 pendula plena^ is one of the finest hardy perennials. It 

 possesses all the elegance of the single variety in its foli- 

 age ; while the mass of its pure white flowers is much 

 finer and more showy. It does not grow so high, and is 

 in flower all the season, throwing up a succession of flow- 

 er-stems until frost. The tuberous roots of this species 

 must be divided with care in August, to have a strong 

 bloom the following season ; care must be taken to pre- 

 serve an eye on each tuber, as in dividing the Peony, or 

 the root may fail. Sometimes sprouts will be thrown out 

 from the tuber, but not commonly. 



S. lobata* — Lobed-leaved Spiraia. — Queen of the Prai- 

 rie. — A species, indigenous in the middle States. The 

 flower-stems are two feet high, terminated by corymbs of 

 deep-pink or red flowers. It is not so long in bloom as 

 the last species and varieties, but fine in its season ; in 

 July. Leaves pinnate, glabrous; the odd leaflet large,
