    Type
    Type: Tanzania, Lushoto District: Usambara Mts, Silai, Holst 2304 (B!, holo.; K!, iso.)
    Habit
    Terrestrial or less often low epiphyte or lithophyte.
    Rhizomes
    Rhizome ± 4 mm diameter, erect or ascending, with concolorous brown narrowly triangular entire scales up to 3 × 0.5 mm at the base.
    Leaves
    Fronds tufted, dimorphic or uniform, fertile fronds proliferous, 1.5–2 times as long as the sterile non-proliferous fronds.
    Stipes
    Stipe matt-greygreen, 5–12 (sterile) or 6–26 cm (fertile) long, 1–1.5 mm diameter, at first with sparse lanceolate-acuminate scales ± 1 mm long, similar to those on the rhizome, later becoming subglabrous.
    Leaf lamina
    Lamina thinly coriaceous, 1-pinnate; sterile lamina broadly lanceolate to ovate, 6–15 × 3–8 cm, pinnae closely spaced and not proliferous. Fertile lamina narrowly lanceolate to lanceolate, 13–27 × 5–8.5 cm, widely spaced and proliferous below the terminal pinna or occasionally on the pinna midrib.
    Leaf veins
    Veins forked; lower pinnae similar to others.
    Pinnae
    Pinnae decreasing in size towards the apex of the frond, terminal pinna similar to other pinnae, bearing a bud at its base in fertile fronds. Pinnae in 5–12 pairs, alternate, subsessile, asymmetrically ovate to lanceolate and often slightly falcate, 2–6 × 1–2.3 cm, base unequally cuneate, the lower pinnae often with a pronounced lobe on the acroscopic side, margin serrate to sharply crenate, apex acute to attenuate, glabrous except for a few small brown scales along the costa below.
    Rachis
    Rachis similar to stipe.
    Sori
    Sori several to many, along the veins from near the costa to halfway to the margin, linear, 3–8 mm long, indusium entire, 0.4–0.8 mm wide, membranous.
    Figures
    Fig. 3: 10–11, p. 19.
    Ecology
    Moist forest, where it may be common; (300–)900–2000(–2300) m
    Conservation
    Widespread; least concern (LC)
    Note
    This species rather resembles small plants of A. elliottii. The similar A. mossambicense Schelpe is only known from two sites in Zimbabwe and Mt Gorongosa in Mozambique.
