Empire is easy and frequent. The present plant is an in- 
stance, among many, of this nature. According to Clusius 
the species was brought by the way of Constantinople to 
Vienna, about 1592; but had entirely disappeared, until 
lately reintroduced through Moscow by Mr. Griffin; with 
whom it seems to thrive in the open border as well as the 
common sort; but flowers rather later in the spring. 
Plicatus had never been entered as a separate species in 
any of the botanical works since the promulgation of the 
Linnean System, till it appeared in the supplement of the. 
Flora Taurico-caucasica, where it is distinguished from 
nivalis, by being larger in all its dimensions, by, the two 
curious longitudinal plaits within side the leaves, a shorter 
peduncle, and the larger green mark of the three smaller 
petaloid segments of the corolla. Its permanence as a 
species is said to have been experimentally proved by Dr. 
Fischer in the Gorenki garden at Moscow. . |

The genus is distinguished from Leucosum, by three al- 
ternate segments of the corolla being much smaller than the 
other three, of a thicker consistence. and notched at the 
end; and from Srrumaria by the anthers being inverted and. 
bursting at the upper end only.
