the plants, and he has referred to the following notices as

SECTION IV.—VEGETATION IN LAPLAND. 
In Lapland, as has been mentioned, ‘ Wahlenberg’s 
edition of the Flora Lapponica describes 1087 species of 
plants found in Lapland, more than double the number 
observed hy Linneus. Of this number only 496 are 
perfect plants; the remaining 591 are cryptogamous. Of 
grasses there are 102 species; of algze, 55; of fungi, 94; 
of musci, 200 ; and of lichens, 207. Of the perfect plants, 
the snowy Alps contain 93 species; the subalpine region, 
125; and the woody region, about 313. Of trees 
(reckoning the salices) there are 26 kinds; consisting of 
the Scotch fir, spruce fir, birch, alder, poplar, mountain 
ash, bird-cherry, and nineteen species of willows. There 
are no fruit trees in the country, but a variety of berries 
are spontaneously produced, such as black currants, rasp-
