Some similarities to : Mossy Sandwort (Arenaria balearica) another mat-forming perennial which, at 5cm, is potentially shorter than Cyphel (up to 8cm) but unlike Cyphel, the petals are white and much longer than the sepals, and moreover usually present, and the leaves are ovate to rounded (rather than the linear-lanceolate of Cyphel).

Slight resemblance to : Moss Campion (Silene acaulis) but that is taller still at 10cm, with petals present and reddish and moreover nicked. This grows in similar mountain-top places in the North-West of Scotland such as rocky ledges and scree and also near the sea at the furthest reaches.
