    Dryopteridaceae, JP Roux, M Shaffer-Fehre, B Verdcourt. Flora of Tropical East Africa. 2007

    Type
    China, Szechuan, Mupin, Wilson 2614 (BM!, holo.)
    Habit
    Terrestrial or lithophytic.
    Rhizomes
    Rhizome suberect, to 13 cm long and 1 cm in diameter, rarely branched, with dense roots and brown linear paleae to 12 × 1 mm, ending in acicular cell
    Leaves
    Fronds tufted, 8–12 in number, to 1 m long.
    Stipes
    Stipe brown near base, straw-coloured higher up, 35–45 cm long, 5 mm in diameter, with adaxial groove, sparsely to densely paleate, paleae ovate, 13–23 × 7–9 mm with fimbriate margin and darker central part.
    Leaf lamina
    Lamina herbaceous, pale to dark green, narrowly elliptic in outline, (33–)47–63 × 8–16 cm, 2-pinnate.
    Rachis
    Rachis straw-coloured, densely paleate with paleae similar to but smaller than those on stipe, to 9 × 3 mm; pinnae up to 29 on each side of the rachis, the lowermost reduced and deflexed, the largest to 9 × 2 cm; pinnules up to 12 free pairs per pinna, to 12 mm long, long-aristate; venation clear, costa with dense narrowly ovate to triangular scales with long outgrowths on lower margins
    Sori
    Sori (sub-)terminal on abbreviated vein branches, circular, ± 1 mm in diameter; sporangium with 11–24 indurated annulus cells; indusium persistent, straw-coloured, peltate, circular, repand to erose with small, central processes, maximum radial length 1.1 mm
    Spores
    Spores brown, smooth or tuberculate, spiculate
    Figures
    Figure 10: 9-10, figure 11: 1-3
    Ecology
    Bamboo zone, Hagenia zone, heath zone and moorland, occasionally in moist forest, often near streams, at higher altitudes in sheltered sites; 2350–3650(?–4100) m
    Conservation
    Widespread; least concern (LC)
    Note
    P. transvaalense and P. wilsonii occur sympatrically and often grow side by side. P. wilsonii has slightly shorter and narrower fronds, more pronounced reduced and deflexed of the basal pinnae, and an indusium margin that generally is less clearly sculptured; also, the paleae occur on the rachis, while in P. transvaalensis they are restricted to the stipe and the lower rachis. P. wilsonii is prdominantly a high altitude species – although it does occur at lower altitudes as well, where it overlaps with P. transvaalensis. A number of intermediates occur, and a putative hybrid has been described ( P. × saltum, Roux 1997).
