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

    Type
    Type: Bioko [Fernando Po], Mann 448 (K!, holo.; B!, iso.)
    Habit
    Epiphyte, occasionally terrestrial, rarely lithophytic.
    Rhizomes
    Rhizome scales up to 13 × 2.5 mm long with short hair-points. Rhizome erect, to 20 cm long and 15 mm diameter, with narrowly lanceolate attenuate glossy brown sparsely fimbriate
    Leaves
    Frond tufted, arching, not proliferous, dark-green when fresh, herbaceous.
    Stipes
    Stipe greygreen to black, 18–45 cm long, sulcate, covered with hair-tipped scales at first, becoming glabrous with age.
    Leaf lamina
    Lamina glossy dark to bright green, lanceolate to broadly lanceolate, 50–100 × 19–46 cm, 4-pinnatisect, the acroscopic pinnules more developed, the basal pinnae somewhat reduced.
    Pinnae
    Pinnae up to 25 pairs, lanceolate in outline, up to 26 × 9 cm, the ultimate segments narrowly obovoid to spatulate, 0.8–1.5 mm wide, acute, unequally expanded around the sori, glabrous on both surfaces or with sparse broad-based but rapidly attenuate scales to 2 mm long.
    Rachis
    Rachis and secondary rachises black above, green beneath, with brown broad-based but rapidly attenuate and long hair-pointed scales; secondary rachises narrowly winged for most of their length.
    Sori
    Sori on the acroscopic margins of the ultimate lobes, cup-shaped and protruding from the margin, broadly oblong, 1–1.5 mm long.
    Indusium
    Indusium broadly elliptic to broadly oblong, membranous, entire, to 1 mm long/wide.
    Figures
    Fig. 8: 4–6, p. 47.
    Ecology
    Moist forest, often along rivers, often epiphytic on tree ferns, less often on other trees, sometimes terrestrial, rarely on rock; 800–2400 m
    Conservation
    Widespread; least concern (LC)
    Note
    I have made A. spathulatum of Peter = A. morogorense a synonym; the differences indicated by Peter do not hold true, as they are based on the incomplete type – consisting only of the upper part of the frond, and so the shorter stipe (which is not present) and the fewer pinnae (based on an incomplete frond) cannot be upheld. Not easily confused with any other Asplenium.
    Distribution
    Range: West tropical Africa to Ethiopia, and S to Malawi, Mozambique and Zimbabwe Flora districts: U2 U3 U4 K3 K4 K5 K7 T2 T3 T4 T6 T7 T8
