PHANEROGAMIC FLORA OF SPITZBERGEN. 139 
— Under the bird-cliffs as far as Brandywine Bay, very common. The 
pods are sometimes nearly spherical. This form has been taken for 
C. officinalis by Sommerfelt and Vahl. 
Var. B. prostrata. Minor, 1-3-pollicaris, procumbens, foliis radi- 
calibus ovatis basi truncatis vel cordatis vel in petiolum decurrentibus, 
integerrimis vel basi utrinque unidentatis, caulinis sessilibus oblongis 
subintegris, siliculis. ovati-ellipticis subvenosis.—This variety is the 
C. Danica of Solander, Hooker, Vahl, and others; it is also the Q. 
grenlandica of Solander, according to specimens in the Riks Museum. 
Martin brought it from Spitzbergen in 1758. It is very general on 
all the coasts and islets. 
Var. y. levigata. Siliculis angustioribus elliptico-lanceolatis, sub- 
aveniis a var. prostrata differt.—On sand near the shore, scarce along 
the north and west. 
I kave found transition forms between all these varieties. I have 
consequently reduced to a single species the five hitherto recorded as 
from Spitzbergen. C. officinalis, L., Smflt. and Vahl, belongs to var. 
typica; C. Danica, Solander, Hooker, and Vahl, is var. prostrata, as is 
also Solander’s C. grenlandica ; C. Anglica, R. Br. and Smflt., is a 
transition form between var. typica and var. prostrata. I have re- 
tained R. Brown's name, C. fenestrata, in preference to the older 
Linnean €. grenlandica, because R. Brown's description enabled us 
first unmistakably to recognize the species. 
SILENACEÆ, Braun. 
25. Silene acaulis, Li.—On sand- and gravel-terraces at the base of 
the mountains, on the northern and western coasts, not very scarce. 
At Magdalena Bay it has been found 2000 ft. above the sea. In flower 
at Treurenburg Bay and Wide Bay early in July, and with ripe seed- 
vessels at Smerenburg Bay 1st September. 
26. JFahlbergella apetala, L., Fr. Lychnis apetala, L., Wbg., R. 
Br., Hooker; Melandrium apetalum, Fenzl., Ledeb., Hrtm.—North- 
west coast ; also at Hinlopen Strait, but scarce. Past flower on Norse 
Island and Cross Bay at the end of July; and seed almost ripe at — 
Lomme Bay August 24th, and at Ice Sound in September. This 
plant is more downy than the Scandinavian one, but is otherwise like it. 
27. W. affinis, Fr. Herb. Norm. fasc. 9, n. 36.—At Wide Bay in the 
north. Early in July in flower. This differs from the preceding in
