    Type
    Type: Tanzania, Kilimanjaro, [Dschagga], Kersten in von der Decken 40 (B!, holo.)
    Habit
    Terrestrial, low epiphyte, or lithophyte.
    Rhizomes
    Rhizome shortly creeping to suberect, up to 5 mm diameter, with shining dark brown clathrate narrowly triangular entire rhizome scales up to 6 × 0.3–1 mm, attenuate and ending in a hair-tip.
    Leaves
    Frond shortly spaced or tufted, arching, firmly herbaceous, generally 30–50 cm long, not proliferous.
    Stipes
    Stipe matt brown to black, 9–40 cm long, with appressed scales similar to those of the rhizome near the base, subglabrous above.
    Leaf lamina
    Lamina dark green on upper surface, ovatetriangular in outline, (8–)20–33(–60) × (4–)10–27 cm, 3–4-pinnate to 5-pinnatifid, finely dissected, basal pinnae the largest, apex decrescent.
    Pinnae
    Pinnae in 15–20 pairs, broadly ovate or triangular in outline, up to 17 × 10 cm, ultimate segments wedgeshaped or narrowly obcuneate, up to 8–10 × 2–4 mm, apex doubly serrate-truncate with teeth to 2 mm long, glabrous on both surfaces or with a few minute scales beneath.
    Rachis
    Rachis and secondary rachises dark brown, with sparse pale brown ovate-acuminate clathrate scales 1–2 mm long.
    Sori
    Sori 1–3 per ultimate segment, 1.5–6 mm long.
    Indusium
    Indusium linear, membranous, entire, 0.3–0.4 mm wide.
    Figures
    Fig. 8: 1–3, p. 47.
    Ecology
    Deeply shaded moist forest; (1600–)1700–2300(–2700) m
    Conservation
    Widespread; least concern (LC)
    Note
    The name has been spelled as linkii in some of the literature, but the protologue uses linckii with a ‘c’. Linck was a collector on the von der Decken expedition. There is a link with A. albersii, a 3-pinnatisect taxon. A. albersii var. eickii has very narrow rhizome scales, about 0.3 mm wide, but without the paler margin such as albersii is supposed to have; the lamina is 4-pinnatisect, and the sori 1.5–3 mm long. The protologue already stated “this variety resembles in habitat more A. linkii [sic] Kuhn, as the lamina shape is ovate; but rhizome scales are typically A. albersii.” With this last statement I disagree. Several specimens from U 2 that are 3-pinnatifid or 3-pinnatisect to 3-pinnate could be intermediate, but as they lack basal parts it is impossible to be quite certain: Thomas 2039 from Butale, Esterhuysen 25313 from Bujuku Valley, Thomas 1431 from Bwamba Pass, Thomas 2424 from Mt Mgahinga, Rwaburindore 2894. These specimens are from slightly higher altitudes, 2300–2600 m. Burrows states this resembles a finely-divided form of A. aethiopium or A. uhligii. I agree; Holst 3865 only has the lowermost 2nd-order pinnules divided, and so is only just 4pinnatisect. Chaerle, in his unpublished Ph.D. thesis, keeps A. decompositum separate, distinct in its lamina dissection and thinner rhizome, as well as lamina shape.
