It is a distinctive plant with a design so characteristic that, once seen a copy, never to be forgotten. Before traveling to Madeira had seen a picture of him online, but I had forgotten about him and not looking especially. My obsession was to find the Asplenium anceps, ancestral grandfather Macaronesian fern of Asplenium azomanes of Mallorca. Walking and scanning with it the very thick forest that borders the road to the summit of Monte Poiso, my attention these dark fronds in the shadows are almost black. Were covered with dry branches and pine litter fall. Nothing more to see their leaflets in the form of small scythes knew I had found one of the rarer endemic flora of Madeira.
The Polystichum falcinellum is easy to hybridize with Polystichum setiferum, leading to a beautiful hybrid with a medial aspect, the Polystichum x maderense.
