Description: |
Rhizome creeping or ascending, up to 7 mm thick. Rhizome scales 3-7 mm long, linear-attenuate, light-dark brown to blackish, entire or with a few hair-like outgrowths, ending in hair-point. Fronds tufted. Stipe 8-40 cm long, dark brown, covered with hair-like scales when young, subglabrous with age. Lamina very variable in size, shape and degree of dissection, 12-64 cm × 3.7-27 cm, strongly 2-pinnatifid to 3-pinnate, ovate to narrowly lanceolate in outline with the basal pair or 2 of pinnae usually reduced in size. Pinnae ovate to narrowly lanceolate, apex acute, sometimes drawn out into a thin, narrow terminal segment; margins irregularly toothed. Pinnules upper surface subglabrous, lower surface sparsely set with twisted scales. Sori linear, 3-14 mm long, set along flabellate veins, sori more than one per lobe, indusiate. |
Notes: | The extreme variability of this species makes it difficult to distinguish it from others in this group. A. aethiopicum has recently been split up in 4 subsp.(J.P.Roux,2001): subsp.aethiopicum, subsp.dodecaploideum ,subsp. filare and subsp. tripinnatum . We have lumped these for the time being. These subspecies usually grade from one to the other and are hard to distinguish without a strong microscope to examen the spores. |
