Norway with much shorter appendages than have those found 
by H. Mürrer in the Alps and by myself in Greenland. 
The bases of the filaments are slender and crowded in 
between the nectary and the thick base of the corolla 
(Fig. 26 A). Their form and hairiness is shewn in figure 
26 H, N, etc. Besides the long hairs, small papille also occur.

A—H, From West Greenland, near Holstensborg; /—N, from Finmark (Sakkabani, 375 m. 
above the level of the sea). A, The flower is beginning to open, the greater part of the 
pollen has been already shed; pollen is lying upon the stigma. 8B, Flower (about 2/1). 
€, The corolla seen in front view, shewing the stigma inside the throat. D, The calyx 
and the corolla seen from below. Z, The base of the ovary. F, A flower in longitudinal 
section (about 47/2). G, Pollen tetrad. A, Stamen. J, Even in such a bud the anthers 
are open and have shed their pollen. A, Transverse section of corolla shewing that 
the hairs usually occur in ten longitudinal rows. Z, M, The same flower; the pollen 
is shed and is lying on the hairs of the corolla and in the mucilage upon the stigma. 
N, Stamen. (E. W.) 
In some cases the filaments were not as hairy as were those 
figured by H. Mürzer and by Linnman or as were my specimens 
from the west of Finmark. 
Honey is secreted by the ten-lobed disk at the base of 
the ovary (Fig. 26 F, L). 
The flower is probably at first protandrous for a short time 
and then homogamous (according to Porrius homogamous in Lap-
