Amongst the material of the genus Sagina collected by Rostrup, 

 some specimens were found which I must regard as a hybrid 

 form between S. procumbens and snbnlata. A hybrid like this is 

 mentioned briefly (according to reports) by E. Martin in his above- 

 mentioned paper; in »Bull. de la Soc. Bot. de France« we find the 

 following rejjort: »Sagina qui parait étre un hybride produit entre 

 la ^S. procumbens, dont il a le port el les tiges radicantes, et le 

 S. subulata, dont il a la pubescence et qu'il rappele en partie: 

 M. Boreau lui a donné le nom de S. micrantha.« Without having 

 any knowledge of this paper Rostrup, in Botan. Tidsskrift 1895, states 

 that »in the hollows between the downs (at Klitmoller in Thy, Jut- 

 land) a hybrid, Sagina procumbens x subulata was found at several sta- 

 tions amongst the parent piants.« There is no description of it, but in 

 the collection of the Botanical Gardens in Copenhagen there are some 

 specimens from the stated habitat, and these I have been able to 

 examine. The hybrid resembles in habit mostly S. procumbens, but 

 it has a more vigorous rootstock of several years standing. The 

 leaves are glandular-ciliate, the peduncles long and below the flowers 

 glandular-hairy; flowers are smaller than those of S. subulata, but 

 somewhat larger than those of S. procumbens; capsule not developed; 

 no seed. 



The Færoese specimens correspond to tlie Danish ones, and are 

 from the following localities: Str. : Glyversrejn (R. , sub. nom. S. pro- 

 cumbens) and Ost.: Ejde (R., sub. nom. S. subulata), but a further exami- 

 nation will doubtless prove it to be more wideh' distributed. 



74. S. subulata (Sw.) Prsl. 



Common in Ijare, gravelly somewhat damp spots outside enclosed 

 fieids and on the hills up to a height of 500 m. 

 Fl. June — Julj'. Fr. August— September. 



Sagina nodosa is reported b}' Landt (p. 197) to »grow together with the 

 preceding (i. e. Spergiila arvensis) by Landevaag church,« but as it has not been 

 met witli there Ijy others, it is very probable that Landt has confused it with 

 a Spergnla arvensis with stems strongly swollen at the nodes. 



75. Silene acauiis L. 



Common on the hills, and often right down to tlie sea on fairly 

 dry, gravelly soil; sometimes bears white flowers. 

 Fl. May — June. Fr. July — August.
