Druce (A.distentifolium Tausch ex Opiz var. flexile (Newm.) Jermy) A distinct taxon similar to A . distentifolium in frond texture and cutting although the pinnae are smaller and have fewer pinnules or lobes. The fronds are characteristically reflexed and appear adpressed to the ground—a character retained in cultivation. A.fdix-femina produces, especially in mountain habitats, an ecotype with a similar habit which may be confused with this species; the presence of indusia will distinguish it. 4 6 0 5 4 3 2 1
