    Aspleniaceae, Henk Beentje. Flora of Tropical East Africa. 2008

    Type
    Type: Ethiopia, Shashamane District: road to Adaba, de Joncheere ETS 50 (herb. Pic. Serm. 26870)
    Habit
    Epiphyte, lithophyte or terrestrial.
    Rhizomes
    Rhizome short, erect, with chestnut-brown triangular long-attenuate rhizome scales with entire or fimbriate-lobed margin, ending in hair-tip and (5–)7–11 × 2.5–4 mm.
    Leaves
    Fronds tufted, erect, olive-green, not proliferous.
    Stipes
    Stipe matt brown, sometimes green beneath, 8–30 cm long, with dense scales near base, otherwise with scattered narrowly triangular scales to 10 × 3 mm.
    Leaf lamina
    Lamina papyraceous, elliptic to oblong-elliptic in outline, 18–47 × 7–15(–24) cm, 1-pinnate; lower pinnae slightly smaller, apical pinnae gradually decrescent.
    Pinnae
    Pinnae in 14–24 pairs, equidistant, stalked, triangular or lanceolate-triangular, (2–)4–8(–12) × (0.7–)1.2–1.6 cm, base unequal, the acroscopic base broadly cuneate, the basiscopic base narrowly cuneate-excised, margin deeply serrate with often bifid teeth, apex long-attenuate, glabrous above, sparsely scaly beneath.
    Rachis
    Rachis brown, with two narrow green lines, with sparse scales.
    Sori
    Sori many per pinna, at a 45° angle to the costa, elliptic, 2.5–6 mm long.
    Indusium
    Indusium membranous, entire, 1–1.5 mm wide.
    Figures
    Fig. 5: 7–8, p. 30.
    Ecology
    Moist upland forest; low epiphyte, lithophyte or terrestrial; 1200–2500 m
    Conservation
    Widespread; least concern (LC)
    Note
    Faden et al. 71/891 from K 4, Mt Kenya, Castle Forest Station, Nov. 1971, is this species but has the acroscopic base produced into a lobe on many of the pinnae. I believe this is just a form. Faden 72/306 and Kerfoot 3764 from K 5, and Faden 69/94 from Mt Kenya have much smaller pinnae (2–3 cm long) and smaller rhizome scales. I would have said that these might represent an allied but separate taxon, if other sheets of Faden 72/306 had not shown gradual variation to the normal form of A. smedsii. Pócs & Lundqvist 6475/G from T 6, S Uluguru above Kibungo mission, Oct. 1971, is probably this species but has pinnae to 15.5 × 2.9 cm; it lacks a rhizome. Close to A. boltonii but not proliferous and with slightly different pinnae, as well as broader rhizome scales. Tanzania T 6, Morogoro District: Kanga Mountain, Dec. 1987, Lovett & Thomas 2760! is most likely this taxon but has more dissected pinnae, the individual pinnae being lobed halfway to the costa.
