air on long stalks (Fig. 10). The violet- purple, urceolate 

 corollas, which are covered with red glandular hairs, usually 

 turn their throats downwards (Figs. 10, 12). I have found the 

 flowers to be scentless (Bessels mentions them as fragrant). 

 They are 9 to 1 1 mm. in length. 



The flower is protogynous for a short time (Greenland and 

 Finmark), and then becomes homogamous (as also observed by 

 LiNDMAN and Ekstam). Even in the bud, while the anthers are still

A, A young fluwer which has just expanded; only two of the anthers have opened: pollen 

 already seen upon the stigma (July 6, 1884). B, A Яолувг the anther and stigma of which 

 are at the same level. C, A third flower, also young, newly expanded, in which, as in B, 

 the pores and stigma occur at the same height, Vato^Ai that of the corolla: the anthers are 

 full (if pollen: only the long stamens are open: quantities of pollen occur upon the stigma. 

 D, The same flower as C, seen from above; the glandular hairs are omitted. E, The pistil 

 and the nectary seen from above. F, Anther. G, Pollen tetrad. H, Base of the flower- 

 stalk with the two bracteoles. (E. W.. 1885.) 



closed, the five-lobed stigma (Fig. \2E) is glistening and viscid; 

 but immediately upon the slight expansion of the corolla the 

 anthers on the longest stamens may be found to have dehisced 

 and the pollen-tetrads (Fig. 12 G^) to have been shed upon the 

 stigma. There are two elongated pores at the apex of the 

 anthers (as shewn in Fig. 12 F) which have no appendages. 



The pollen may be so dry and may lie so loosely in the 

 anthers that when the flowers are shaken slightly it flies out
