In 1872 the author visited the Kola-peninsula on a subscri- 
bed journey for collecting vascular plants and mosses. The 2 
most interesting plants found are mentioned in this letter; as . 
for the mosses see next paper. The subscribers for mosses got 
a fine collection of 200 specimens, the more welcome as there 
were many rare species and as all names bad been revised 
by professor Lindberg.

(Bot. Notiser, 1873, p. 14-81). 
Vascular plants as well as mosses are treated. Cephalozia 
islandica, Hypnum revolutum (Miti.), Encalypta brevicolla, 
E. affinis Hedw., Dicranum molle Wils., Brachythecium her- 
jedalicum, Orthothecium rubellum (Mitt.), Campylopus bre- 
vifolius, Cinclidium subrotundum, Sphagnum Angstroemii

This paper gives the results of a journey in 1877 to the 
northern parts of Osterbotten and the western parts of Kemi 
Lappmark, the region visited extending from the polar cirele 
in the south to 67° 438 n. lat. inthe north, and from the rivers 
of Muonio and Tornio in the west to the river Ounasjoki in 
the east. The author calls attention only to those vascular 
plants and mosses that are more common and so frequent as 
to form an essential part of the vegetation. According Lo their 
height the plants are divided in 7 strata, the lowest stratum 
rising only 3 cent. over the ground, the second stratum reac- 
hing a height of 1 decim., etc. From 76 different places or 
situations the plants ofeach stratum as well as their frequency 
are enumerated, the mosses, of course, all belonging to the 
first stratum. The plants of one stratum are according to their 
habitus or general physiognomy divided in forms; as for 
mosses the author speaks of Sphagnum form, a Polytrichum 
form, a Hylocomium form, an Amblystegium form (A. fluitans 
and resembling, not systematically allied, mosses that seem 
Lo thrive together) and an Astrophyllum form. Forms that 
are found in the same place constitute a formation. Of for- 
mations a great many are distinguished and named, the name 
being derived from the forms constituting the formation and, 
not from the kind of station in which the formation usually 
occurs, as the same formation may often be found in different 
situations. As example of some of these formations may be 
mentioned Abiegna-hylocomiosa , Pineto-betuleta-hyloco- 
_ miosa, Betuleta-muscosa, Sphagneta-myrtillosa, ete.
