Description (by 't Hart & Bleij in IHSP, 2003) :
Laxly caespitose perennial herbs with basally densely glandular-pubescent, creeping stems with short ascending non-flowering shoots.
Leaves alternate, patent or appressed, sessile and scarcely spurred, linear-cylindrical to ovoid-globose, obtuse or rounded, subterete but somewhat flattened on the upper face, glabrous or sparsely pubescent, green but often reddish, 4 – 20 (-25) mm, flowering branches erect, 5 - 18 (-30) cm.
Inflorescences many flowered rather dense subcorymbose cymes, freely branched, bracteate, bracts 1 per flower, small, pedicels short.
Flowers 5-merous, sepals broadly sessile, basally connate, ovate to triangular, 1 – 2 mm, petals free, lanceolate, 2 – 4.5 mm, subacute, white or rarely pink, filaments white, anthers red.
Cytology : 2n = 34, 51, 68, 85, 102, 136
Note :
1. Sedum gypsicola was described by Boissier & Reuter 1842 from a plant growing on gypsum hills near Aranjuez, Rivas and la Guardia (Spain). It differed from S. album by pubescent-velvety leaves and stems.
Hamet (1929) reduced it to a variety of S. album while Maire (1932) considered it a subspecies of S. album.
't Hart however did not accept either of these classifications, stating that "the 2 species have very different distribution areas". This has turned out not to be correct. Ray Stephenson has found S. gypsicola occurring only 10 km distant of S. album.
In view of the fact that the only difference between S. gypsicola and S. album consists in the papillate leaves of the former which - under extremely wet conditions - even are likely to disappear thus making it indistinguishable from S. album - it is much more appropriate to include S. gypsicola in S. album and not to treat it as a separate species any longer.
