Description:
Aquatic species. Rhizome widely creeping, up to 10 mm in diameter; rhizome scales very dark brown, lanceolate, entire. Fronds spaced apart, arching, firmly membranous, transparent when submerged, trimorphic. Sterile submerged fronds: stipe 2.5-7 cm long, lamina ovate to elliptic, 7.5-17 × 3.5-7 cm, pinnate to deeply pinnatifid towards the apex, not gemmiferous; pinnae deeply pinnatifid towards the frond base, becoming subentire towards the apex, angled at ± 45° towards the apex. Sterile aerial fronds: stipe 11-16 cm long, lamina ovate to elliptic, 16-32 × 12-15 cm, pinnate, terminal portion pinnatifid, not gemmiferous; pinnae oblong-lanceolate, apex pointed, base unequally wedge-shaped, sessile to asymmetrically adnate, margins entire to widely and shallowly serrate. Fertile aerial fronds: similar to sterile aerial fronds but with the pinnae much narrower and thus more widely spaced. Sporangia either covering the whole undersurface of the pinna or in irregular patches.
Notes: Can be distinguished from other species by its trimorphic not gemmiferous fronds and its aquatic habit.
Derivation of specific name: heudelotii: named after J. Heudelot, a French explorer who collected plants in Guinea and Senegal from 1828 to 1837.
Habitat: Grows partly submerged in streambeds or along streambanks on deeply shaded rocks in forest, especially in waterfalls.
Altitude range: (metres) 300 - 2400 m
Worldwide distribution: An essentially tropical African species, widespread in West and East Africa and Zambia, rare in Mozambique and Zimbabwe and exceptional in Limpopo in South Africa.
