Confused by American botanists with Arenaria norvegica Gunn. 
Fl. Norv. ii. 144, no. MC, t. 9, figs. 7-9 (1772) = A. ciliata, var. 
norvegica Hartm. Skand. Fl. ed. 3, 105 (1838) = A. ciliata, var. humi- 
fusa Hartm. |. c. ed. 4, 141 (1843); also with A. ciliata L. Sp. Pl. 425 
(1753); but differing from each of those European plants in many 
characters. In both A. norvegica and A. ciliata the leaves are more 
obviously nerved and even those of the flowering branches usually 
subtend small axillary fascicles, and in A. ciliata the leaves are strongly 
ciliate. In both A. norvegica and A. ciliata the calyx is campanulate 
to hemispherical, in fruit 3-4 mm. in diameter; and the sepals are 
oval, acuminate, and usually strongly nerved, those of A. ciliata 
often ciliate at base. In both the European species the petals are 
oval and distinctly longer than the sepals; and both have ebony- 
black seeds, those of A. norvegica coarsely rugose, of A. ciliata dis- 
tinctly but more finely rugose.
