Notes

Haplopteris guineensis var. guineensis is a small epiphytic fern, with a shortly creeping rhizome covered by scales, black and lanceolate, darker in the center, with a colorless light. The frond is linear-lanceolate, 10 to 60 cm long and 0.4 to 1.2 cm width. The stipe is 2-5 cm long, blackish at the base. The end of the leaf blade is acute, mucronnate, with terminal hydathode. Midrib only appears only at the base of the frond. The lateral ribs are not visible, except for the young fronds. The sori are marginal, immersed. The plant usually grows on the trunks of trees in the gallery forests and rainforests.
