Leaves: Narrowly lanceolate to lanceolate, 5-15 cm long, 0.5-1.2 cm wide; rachis not winged, green throughout; pinnae in pairs, egg-shaped to oblong, 3-7 mm long, 2-5 mm wide, with few notches towards the tip.
Notes: Some authors advocate the use of Linnaeus' name A. trichomanes-ramosum, which should be rejected as a trinomial. The International Code of Botanical Nomenclature (Tokyo Code) suggested use of the name "A. ramosum L." and at the same time, Zimmer & Greuter (1994) proposed to reject this name and retain A. viride.
