Annual or biennial. Flowering branches erect or suberect, more spreading, and more distant, 
than in A. ciliata and in A. norvegica. Leaves laxly arranged, divaricate, linear to narrowly 
elliptical or oblong, acute, about 3 — 4 mm. long and 1 — 2 broad, acute ; of the flowering branches 
oblong-elliptical, rather acute, about 5 mm. long and 3 broad. Inflorescence with 1 — 2 flowers. 
Pedicels up to 5 times as long as the calyx. Flowers about 1 cm. in diameter; late June to 
September. Sepals narrowly ovate, acute, carinate, glabrous. Petals about twice as long as the 
calyx. Stamens 10. Capsule broadly ovate, longer than the calyx, carpellary teeth about a fifth as 
long as the whole capsule. 
Whatever be the relation of Ar. ciliata and Ar. norvegica , we have no doubts as to Ar. gothica being 
specifically distinct. 
This very rare species (only known from southern Sweden, Yorkshire, and Switzerland) was discovered in Yorkshire by 
Mr Lister Rotheray, of Skipton, in June, 1889 (cf- Journ. Bot. xxvii, p. 314). It is curious, if the plant is indigenous, that 
it was not noticed before 1889; but, on the other hand, it is difficult to understand how it could have been introduced 
except by intention. The plant seems to be gradually extending its range in Yorkshire. 
Very rare; on loose soil close to a railway station and on cart-tracks on carboniferous 
limestone in the north of the West Riding of Yorkshire, at an altitude of 310 to 490 metres. 
Southern Sweden, Switzerland.
