40 PERENNIALS. [March. 



Li/thrums. A few species flower well, and hav-e small pink 

 blossoms in great profusion, L. aldtum, L. vtrgdtum, L. 

 diffusum, L. rose.iim, and L. lanceoldtum. They will grow in 

 any common garden soil if not too much shaded ; and flower 

 from June to September. 



Mimiilus, Monkey-flower. A few species may be culti 

 vated. They will grow in any soil or situation. M. lutem 

 and M. rivularis are the best. M. moschdtus has a very 

 strong musk scent, to many agreeable. The former two have 

 large gaping flowers, of a golden yellow, and beautifully 

 spotted with purple in the interior; they all grow in moist 

 situations. 



Mondrdas, a fine native genus, and showy. The foliage of 

 several of the species is aromatic, and resembles mint. M. 

 cliilyma has long scarlet ringlet flowers, in headed whorls ; 

 M, kalmiana, flowers very long, and a beautiful crimson, 

 with fragrant leaves. M. Rmselliana has red and white 

 flowers ; curious and handsome. M. punctata has yellow 

 and red flowers ; they grow in any common soil. 



Mathiola is the generic of the Stock-gilly. None of them 

 will survive severe winters in this latitude; yet many of 

 them are indispensable in the flower-garden. M. simpli- 

 cdulis, Brompton-stock, and its varieties, with M. incdna, 

 Queen-stock, and its vaiietics, require the protection of a 

 gvxl frame in winter; and about the end of this month, or 

 beginning of next, plant them in good, light, rich soil to 

 flower, which they will do all summer, if attended to with 

 frequent supplies of water. M. dnnua has about forty varie- 

 ties, valuable for flowering the first year from seed, and 

 are all annuals. They ought to be sown on a gentle hot-bed 

 about the first of this month, and carefully picked out so as 

 they may be ready to transplant about the end of April or 

 the first of May. Plant them in light, rich soil, and they 

 will flower profusely through the season ; if it is very dry, 

 they must be watered to keep them growing. The scarlet, 

 white, and purple varieties are the finest ; but there are 

 many intermediate sorts, all handsome. M. yldbra is the 

 Wall-flower leaved stock, and requires the same treatment 

 as the former two. There are about twenty varieties of this, 

 all various in colour. In planting any of these into the open 

 ground, choose cloudy weather, except they have been in pots;
