About Pyrrosia confluens (R.Br.) Ching
Pyrrosia confluens, commonly known as the horseshoe felt fern or robber fern, is a common fern native to eastern Australia. It grows as an epiphyte or lithophyte in partially shaded, high-moisture areas, and is often found on rocks or creeping up rainforest trees quite high above the ground. Its distribution is limited to areas north of the Wyong district. This species was first published in scientific literature in 1810 under the name Polypodium confluens, in Robert Brown’s work Prodromus Florae Novae Hollandiae. Brown was a prolific Scottish botanist.
