Cardamine hellidifolia, L. — This curious-looking little mem- 

 ber of the Cruciferae is also a rare plant which grows on gravelly 

 water-margins or broken clefts of weathered rocks. In its 

 flowering state it was rather a puzzle, but in fruit it is very 

 characteristic. 



Draha alpina, L., is another interesting and very handsome 

 member of the same family. It has its southern limits in the 

 Dovrefjeld. 



Polygala amara, L. — This we only fomid in one station on 

 our way to Kongsvold, and not in the Drivsdalen at all. Its hue 

 when growing was, indeed, " deeply, darkly, beautifully blue," 

 its flowers set in denser clusters, and its habit altogether more 

 compact than our Polygala vulgaris. As you see, however, it 

 does not make at all a satisfactory specimen, though that may be 

 owing to its not being properly dried, in which respect, I am 

 soiTy to say, most of the plants we collected suffered. 



Silene rupestris, L., we found everywhere from south to north, 

 and from the sea level to the height of about 5,000 feet. 



Alsine stricta, Wahlen., and Alsine hirta, Hartm., are not 

 found further south than 60°. 



Myricaria germanica, Desv., is a member of the Tamaricacese 

 — a group consisting of only two genera. These really give no 

 adequate idea of this handsome shrub, being only small bits 

 broken from the tops of branches. We were told that it was 

 rather rare in the country, but ^e did not find it so. It flanked 

 the margins of rivers in some places, and covered the surfaces 

 of small river islands with its closely set, fastigiate branches 

 and dense spikes of reddish-purple flowers. 



Lychnis alpina, L., I have included, though it is one of 

 our own Clova plants. Its interest lies in the fact that, while 

 with us it only grows in one district, and then in very small 

 and very few patches, in the Dovrefjeld it was on every road- 

 way, reddening the ground for many a mile, while Astragalus 

 alpinus, L., was quite as common. 



Astragalus orohoides, Hornem., was scarcely so prolific, but 

 Orytrojns lapponica ran it very closely. It was rather dijBBcult 

 to tell the difference between these two when growing even side 

 by side, and both in good condition; but as soon as Oxytropis 

 lapponica was off its first bloom, the livid hue it assumed 

 proclaimed it without further examination.
