weeds, until the plants appear to have increased so 

 as to become too thick, which will not be oftener 

 than every third or fifth year, when the offsets may 

 be placed in a separate patch. The Dog's Tooth 

 Violet may also be increased by sowing the seeds in 

 pots, as has already been observed in the history of 

 other bulbous plants. 



A second species of Erythronium was introduced 

 from North America in 1665, and bears the specific 

 name of Americanum. It flowers a month later 

 than the European species, and is something larger, 

 and of a golden yellow colour. The cultivation is 

 the same, and it is equally calculated to ornament 

 many shady places in the shrubbery, or wilderness 

 scenery. We would place the Yellow Erythronium 

 in the shade of the Purple Rhododendron, as it 

 loves the same soil, and flowers at the same season. 

 INI. Pirolle, in " Le Bon Jardinier^' recommends 

 that the seeds of each of these plants be sown in pots 

 of bog-earth.
