carpets by small streams; it is also to be met with in moss carpets and 

 on rock-ledges on the hills (e. g. Kun 6 at about 550 ni.). 

 Fl. May — June. Fr. very sparingly (August . 

 Martinss report of C. impdticns from the neighbourhood of Thorsliavn must 

 undoubtedly l^e due to a misunderstandiug. 



90. Cochlearia officinalis L. 



Commonly dispersed both on the sea-shore, in clefts of rocks and 

 ravines and on gravelly plateaux on the hills. 

 Fl. Maj'. Fr. July — August. 



It is often perennial and flowers several times (see Fig. 1 by Ostenf. I 

 p. 146) especially when growing amongst damp moss in ravines. 



All the many different forms of Cochlearia, found in the Færoes, 

 pass so imperceptibly into one another, that it seems most natural to 

 name them collectively under one name which includes everything 

 Rostrup 1. c. p. 41 names C. officinalis, C. danica and C. arctica ; true C. 

 danica does not occur on the Islands. 



91. Draba hirta f. rnpestris (R. Br.). 



Found here and there on rock-ledges and in clefts often far up the 

 hills (e. g. Ost.: Fuglefjordsfjæld at about 600 m. and Rejafjældstinde, 

 685 m.) and seldom in low-ljång regions; dispersed over all the Islands ; 

 rarest on Syd. and San do (Syd.: Tværaa (!)). 



The D. corymbosa from Hesto reported by Rostrup 1. c. p. 40. is either a 

 D. hirta which looks rather curious because the pods contain no developed seeds 

 or perliaps a hylirid between D. hirta and D. incana. 

 Fl. June. Fr. July — August. 



92. D. incana L. 



Rather common on all the Islands on rock-ledges and in ravines 

 not so far up the hills as the preceding. 

 Fl. June — July. Fr. July — August. 



Draba verna is reported by Landt to occur here and there on the hills, 

 but this statement must be due to a misunderstanding.

 Accidentally introduced at Thorshavn (R.). 

 t Sinapis alba L. 



Accidentally introduced at Thorshavn (R.) and Kirkebo (!) on Str. 

 Fl. August. 



t S. arvensis L. 



Accidentally introduced; Str.: Thorshavn (R.); Kirkebo (!); Vaago: 

 Sorvaag (R., Lomholt). 



Fl. July. Fr. August. 



93. Subularia aquatica L. 



Grows under water on the gravelly bottom of several small lakes; 

 Sando: lake on Vardebakken at some 300 m. (!), Leinumvatn and Miave-
