Information
A creeping plant often forming dense grey-green mats; stems prostrate, often irregularly ascending, 1–3-furcate; rhizophores drying orange-brown, 2–4 cm long; plants often forming further primary branches from continuation of growth of lower secondary branch upon cessation of growth or death of upper secondary branches, leafy, often radially symmetrical or occasionally slightly dorsiventral in position of leaves. Leaves often brown and papery on the underside, herbaceous, narrowly triangular to linear or subulate, 1.5–3 mm long, 0.25–0.3 mm wide, adnate at base, acuminate at apex, tapering into a usually curved seta 1/3–1/2 as long as the blade, white and opaque when young, often becoming tawny; margins ciliate. Strobili 4–8 mm long, suberect, dorsiventral; sporophylls in 2 ranks on the underside, broader (up to 1.2 mm) and more lanceolate than the leaves, with white seta to 0.7 mm long. Megaspores yellow to orange, 350–440 µm, subgranulate; 3-radiate, ridges indistinct. Microspores vermilion, 40–50 µm, scabrid. Fig. 1/16–1/21.

Notes
The K duplicate of Hildebrandt 2363 could not be found. Czeladzinski has annotated all East African specimens as S. grisea but Burrows keeps S. grisea and S. dregei distinct and records both from East Africa stating that apical leaf setae are about 1/3 the length of the leaf in S. dregei which is more robust with erect branches from a prostrate stem rather than being entirely prostrate; the marginal cilia are stronger and closer in S. grisea. I have been unable to sort out the East African material satisfactorily.
