Description |
Plant creeping, mat-forming; stems repeatedly branched, terminating in short, rather club-shaped fascicles of leaves. Leaves randomly arranged, linear-lanceolate in outline, apex tapering to a point and ending in a white seta 1/4 of the total leaf length, margins with short cilia, 1.5-2 × 0.25 mm, leaves bluish-green when fresh, becoming light creamy-brown to whitish with age and breaking away. Strobilus situated on the end of the branches, 2.5 mm long; sporophylls in 4 lines, lanceolate-ovate on the upper side, broadly ovate on the lower side. |
Notes | S. nivea can easily be confused with S. dregei which has a longer apical seta (a third to a quarter of the length of the leaf blade), sporophylls that are arranged in 2 ranks and leaves that have a dorsiventral arrangement along the stem. |
Derivation | nivea: snow white, referring to the pale colour of the dried leaves. |
