Sedum L. |
S. hispanicum L., Sp. PI. ed. 2:618 (1762). Simple or much-branched, erect or ascending annual or perennial; sterile shoots sometimes present; flowering stems 5-15 cm. Leaves linear, semi-terete to oblong, ± plane, 4-20 mm, glandular-hairy, green or glaucous. Inflorescence a lax to ± dense, 2-4-branched cyme, each branch with 1-8 flowers; peduncles glabrous or more usually glandular-pubescent above. Flowers 5-9-merous, subsessile; sepals c. 2 mm, acute, glandular-pubescent; petals white with pink mid-vein, 4-5 mm; stamens 10, anthers purple; follicles glandular-pubescent or glabrous, white or pale pink, stellate-spreading. 1. Flowers 6-7(-9)-merous; stems much branched; styles 1 mm or more 2. Leaves semi-terete, oblong to linear var. hispanicum 2. Leaves plane, narrowly elliptic var. planifolium 1. Flowers 5-merous; stems simple below inflorescence; styles c. 0.5 mm var. semiglabrum var. semiglabrum Froder., op. cit. 3:82, f. 650-658 (1932). Fl. 6. Limestone rocks, 1700-2200 m. Type: [Turkey A8 Gümüşane/Erzurum] inter Baiburt et Erzurum in aridis elatis Tachkenfom (Taşköprü), Huet du Pavilion 1853 (iso. K! BM!). E. Anatolia. A8 Erzurum: Aras River gorge, 1700 m, Tobey 2109!

A very variable species, especially with respect to the number of flower parts and the degree of glandulosity. S. longi-bracteatum is an extreme variant which is virtually glabrous and in which each flower is subtended by a long 'bract'. However, there is much variation in 'bract' length, even on the type sheet, and similar forms are to be found among European material. For these reasons, I have treated S. longibracteatum as a synonym of S. hispanicum s.s. Of the infrageneric taxa already described within S. hispanicum, var. semiglabrum appears to be the most distinct. This variety approaches S. hewittii but the latter may be distinguished by its larger, obtuse sepals and yellow anthers. |
