ARENARIA 
39 
long ; those of the flowering branches larger and broader, spathulate or elliptical, ciliate at the 
margin, obtuse. Inflorescence i — 2 -flowered. Pedicels 1 — 3 times as long as the calyx, pubescent. 
Flowers large, about 1*4 cm. in diameter; June to September. Sepals narrow, about o'5 cm. long 
and a third as broad, with a white margin. Petals almost twice as long as the sepals. 
Stamens 10. Styles usually 3, free to the base. Capsule broadly ovate. 
There is a specimen preserved in the Sloane Herbarium (in Herb. Mus. Brit.), vol. cxxiv, fol. 6, collected by Lhwyd, 
near Sligo, and sent to Buddie by Dr Richardson. It was probably gathered in 1699, and is named Lychnis alsinoides parva 
flore albo minima. See Journ. Bot. viii, 324 (1870). It seems not to have been found again until 1806, when Dr J. T. Mackay 
gathered it on the limestone cliffs of a mountain adjoining Ben Bulben, in co. Sligo. 
The nearest habitats to the only British station of the plant are in the French Alps and northern Scandinavia. Other 
remarkable plants occurring in co. Sligo are Silene acaulis (an Arctic-Alpine species), Thalictrum alpinum (an Arctic species), 
Polygala vulgaris var. grandiflora (perhaps endemic), Saxifraga nivalis (an Arctic species), and Poa alpina (an Arctic-Alpine 
species). 
Only in co. Sligo, Ireland, where it occurs on the rocky, limestone slopes of the Ben Bulben 
range, ascending to 500 m. 
Northern Scandinavia and Russia, the Alps (ascending to 2500 m.), the Carpathians, and the 
Apennines ; Greenland.

Exsiccata : — Fries, v, 35. 
Perennial, caespitose. Barren branches 
ascending or prostrate. Leaves of the barren 
branches very short (3 mm.); of the flowering 
branches longer (up to 6 mm.) and broader, 
obovate, more or less connate ; all more or 
less succulent, usually obtuse, midrib obscure 
and other nerves not showing, glabrous or more 
or less ciliolate. Inflorescence 1 — 3-flowered. 
Pedicels 1 — 2 times as long as the calyx, a little 
pubescent. Flowers about 8 — 9 mm. in dia- 
meter, smaller than in A. ciliata ; May to July. 
Sepals ovate, acute, 3 -nerved, with a broader 
white margin than in A. ciliata. Petals about 
1 - 5 times as long as the sepals, relatively broader 
than in A. ciliata, obtuse. Stamens 10. Stigmas 
3 — 5. Capsule ovate, longer than the calyx, 
dehiscing about a third of the way down. 
Sutherlandshire — on loose gravel at an 
altitude of 70 m. ; erroneously recorded for 
Orkney ; Zetland — on barren Serpentine rock 
at an altitude of 10 — 13 m., growing with 
Cerastium arcticum forma nigrescens , Arabis 
betraea, and Armenia. 
Iceland, northern Scandinavia.
