in non-glandular hairs. The purely vegetative buds were in 

 all cases smaller, and the bud-scales fewer in number; also 

 in them the young foliar organs were well-developed. 



In Fig. 36 are shown 2 bud-scales (of which the one, B, 

 was uppermost in a bud, and shows a rudimentary leaf- 

 blade), a rosette-leaf and 2 leaves from the part of the shoot 

 with elongated internodes (both kinds of foliage-leaves vary 

 greatly in form). The leaves are hairy, especially at the 

 base, and the stems also are abundantly covered with hairs, 

 especially in the upper part. 



The height of the flowering plant may vary greatly. 

 From Spitzbergen (leg. Тн. Wulff) I had specimens scarcely 

 2 cm high, which nevertheless bore as many as 4 flowers of 

 normal size. It appears that during the end of the flowering 

 period, a rather considerable elongation of the stem, especially 

 of the upper part, takes place; two fruit-bearing specimens 

 from Greenland (Amitasiarsak Fjord) were as much as 36 cm 

 high. 



The development of a "rhizoma multiceps" causes a 

 somewhat tufted growth of the species. One specimen from 

 Hvalrosodde (North-east Greenland, leg. An dr. Lundager) 

 had at the same time as many as eleven flowering shoots, 

 numerous leaf-rosettes and ten dead inflorescence-axes from 

 previous years. This tuft-forming growth must afford ad- 

 ditional protection to the winter-buds, the latter being 

 covered by the numerous withered leaves. 



Haustoria are found on the roots; according to Rosen- 

 viNGE this species is parasitic on Vaccinium uliginosum and 

 Salix herbacea, for example. 



In the fresh condition the root has a slightly yellowish 

 colour, and a somewhat sweetish taste (Nathorst). The 

 radiating clefts, which are formed in the tissue of the root,
