18. Tussilago Farfara L. 



Found here and there in sandy enclosed fields, and in gravel by 

 larger streams. We only found a few specimens. 

 Fl. May— June. 



Order CONVOLVULACEAE. 



t Convolvulus sepium L. 



Found as a weed in gardens at Thorshavn. (R., E. W.) 

 Does not flower. 



Order IV. DIPSACACEAE. 



19. Succisa pratensis Moench. 



Conimon in and outside enclosed fields in damp peaty ground; 

 sometimes bears white flowers; does not grow up in the hills. 

 Fl. end of July. Fr. September.

Order V. ERICACEAE. 



20. Calluna vulgaris Salisb. 



Common in heaths and moors outside enclosed fields; however, 

 seldom occurring as a dominant social species. Grows in low-lying regions 

 and sometimes on hill-slopes, but not on the higher mountains. 

 Fl. beginning of August. 



21. Erica cinerea L. 



Generally mixed together with the above-mentioned and in the same 

 localities, consequently not high up in the hills; seems to prefer sunny 

 spots facing south and west. We found it — in varying frequency — 

 on all the Islands except Fuglo. 



Fl. end of July and beginning of August. 



Erica Telralix is said by Mellvill to have been found at Trangisvaag by Mr. 

 Backhouse, but as none of the many other botanists who have visited Trangis- 

 vaag has found it, I believe this statement is due to a misunderstanding. 



22. Loiseleuria procumbens (L.) Desv. 



Rather frequent in G/7'm/?Ha-heath on the higher hills on the 

 northern Islands ; most frequent in the Nordreoer; not observed on 

 Sando and Syd. It occurs from about 400 m. upwards. 

 Fl. May. Fr. August.
