The twelfth has a perennial fibrous root: the stems erect, three 

 or four feet high, angular and furrowed, tinged with red, leafy, 

 branched in the upper part: the leaves interruptedly pinnate: leaf- 

 lets very unequal in size, sharply serrate, clothed beneath with white 

 down, the end one remarkably large and three-lobed: a pair of 

 rounded serrate stipules are joined to the common leaf- stalk, and 

 clasp the stem: the flowers white, in a large compound cyme, 

 the side-branches of which rise much above the central one: it per- 

 fumes the air with the sweet hawthorn-like scent of its plentiful 

 blossoms from June to August. 



There are varieties with double flowers, and with variegated 

 leaves. 



The thirteenth has a perennial root: the stalks annual, about a 

 foot high, sending out branches from the side the whole length : the 

 leaves for the most part trifoliate, but sometimes single or in pairs; 

 they are about an inch and half long, and half an inch broad, 

 ending in acute points, sharply serrate, of a bright green above, 

 and pale beneath: the flowers in loose terminating panicles, on 

 slender peduncles. It is a native of North America, flowering in 

 June and July. 



Culture. In all the shrubby sorts, this may be performed by 

 suckers, layers, and cuttings. 



The suckers should be taken off in the autumn and planted out 

 where they are to remain, or in nursery-rows, to attain a fuller 

 growth. 



The first sort requires to be cleared of these suckers every two 

 years at furthest. 



The layers should be put down in the autumn or in the spring, 

 and may be taken off and planted as above, in the autumn or spring 

 following: all the sorts may be raised in this way; but it is most 

 proper for such sorts as do not send off suckers. 



The cuttings may be made from the shoots of the preceding 

 summer, and be planted out in a shady border in the early autumn : 

 when they have become well rooted they may be removed and
