Norway with much shorter appendages than have those found 

 by B. MtJLLER 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 jET, iV, etc. Besides the long hairs, small papillae 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

 0, The corolla seen in front view, shewing the stigma inside the throat. D, The calyx 

 and the corolla seen from below. E, The base of the ovary. F, A flower in longitudinal 

 section (about 4 '/a). G, Pollen tetrad. H, Stamen. /, Even in such a bud the anthers 

 are open and have shed their pollen. K, Transverse section of corolla shewing that 

 the hairs usually occur in ten longitudinal rows. L, 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. Müller and by Lindman or as луеге 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 lime 

 and then homogamous (according to Poppius homogamous in Lap-
