Notes

Adiantum schweinfurthii  is a fern with a short rhizome, with brown scales, linear-lanceolate, long-acuminate, entire. The fronds are in clumps, pinnate, oblong-lanceolate, 12-34 cm long (Fig. 8a). The stem and rachis are purple-black and shiny, hairless. The pinnae are pale green, oblong or oblong-lanceolate, 1 to 2.2 cm long and 3-8 mm wide, oblique at the base; higher margins are lobed and serrated but not deeply incised. The lower margin is entire and glabrous. Each pinnae has 4-7 pairs of oblong-reniform sori, often 1 by a lobule (Fig. 8b).
