SPERG ULARI A 
i9 
(a) subvar. hirsuta comb. nov. ; Arenaria marina var. hirsuta Gibson loc. cit., in sensu stricto ! 
leones : — More in Eng. Bot. Suppl. t. 2977, as Lepigonum rupicolum. 
Camb. Brit. FI. iii. Plate 16. (a) Flowering shoot of an erect form, (b) Flowering shoot. ( c ) Stipules 
(one enlarged). ( d ) Calyx enclosing ripe capsule. ( e ) Ovaries (one enlarged). (/) Seeds (enlarged), b—f 
belong to the trailing form. Jersey (E. W. H.). 
Exsiccata : — Lebel (in Herb. Mus. Paris), as S', rupestris ( vel rupicola ) (fide Kindberg op. cit.)-, Linnaeus, 
in Herb. Mus. Holm., as Arenaria media (fide Kindberg op. cit.). 
Shoot glandular-pubescent. 
“In Jersey, it usually grows in the chinks of granite walls and in the interstices of rocks near the sea: in this 
form it is not a showy plant. It also grows on sandy soil near the sea : it then grows in masses, and is by far the 
handsomest of the British species.” (E. W. H., in lilt.) 
The common form of the species both at home and abroad. 
((3) subvar. glabrescens comb. nov. ; Lepigonum rupestre var. glabrescens [Lebel ex] Brebisson FI. Normand. 
ed. 4, 57(1869); Corion rupestre var. 
glabrescens N. E. Brown in Eng. Bot. 
ed. 3, suppl. 49 (1891). 
Shoot glabrous or nearly so, 
not or very little glandular. 
Neither Lebel nor Kindberg, in the 
works here cited, have a “var. glabres- 
cens,” though we find this name attributed 
to them by several authors. Both state in 
their descriptions that the plant may be 
either glandular or glabrescent. 
Very rare ; Plymouth, Devon- 
shire. France. 
On spray- washed rocks, cliffs, 
and walls, near the sea, rarely on 
sand-dunes ; from the Channel 
Isles, Isle of Wight, and Corn- 
wall, along the western coast, 
northwards to the Hebrides; also 
recorded for Norfolk, Edinburgh- 
shire, and Aberdeenshire; Ireland 
— local around the coast and in- 
land at Lough Neagh. 
Northern and western France, 
Spain, Portugal, Italy. 
5 . rupicola x salina comb, 
nov. ; S. rupestris x salina Pugsley in 
Journ. Bot. xlix, 365 ( 19 1 1 ) ! 
Shoot glandular. Stipules 
acute to acuminate. Laminae not 
mucronate. Inflorescence many- 
flowered, rather lax. Pedicels of 
the lower flowers longer than the 
calyx. Petals rose-coloured above, 
white at the base, intermediate 
in size between those of the pu- 
tative parents. Seeds not known. 
As the species of this genus and 
particularly those of the series Rubrae 
are very closely allied, it is highly pro- 
bable that hybrids of them are much 
commoner than the records indicate ; but the fact is not usually recognised that the more closely species are allied the 
more difficult are their hybrids to detect, although the more likely are these hybrids to occur. 
Once found ; Lyme Regis, Dorset. Not known elsewhere. 
Map 9. Spergularia rupicola occurs on the coasts (chiefly coastal rocks and 
cliffs) of the counties which are shaded
