Splachnaceae is a family of mosses, containing around 70 species in 6 genera. Around half of those species are entomophilous, using insects to disperse their spores, a characteristic found in no other seedless land plants. Many species in this family are coprophilous, growing exclusively on animal faeces or carrion. For this reason, certain genera such as Splachnum Hedw. are often referred to as dung mosses.

Deparia (or the false spleenworts) is a genus of ferns. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) places the genus in the family Athyriaceae, although other sources include it within an expanded Aspleniaceae or Woodsiaceae.

Dawsonia superba is a moss in the family Polytrichaceae that is found in Australia, New Guinea, Malaysia, and New Zealand. D. superba is the tallest self-supporting moss in the world, reaching heights of 60 cm (24 in). It has analogous structures to those in vascular plants that support large size, including hydroid and leptoid cells to conduct water and photosynthate, and lamellae that provide gas chambers for more efficient photosynthesis. D. superba is a member of the class Polytrichopsida, although it has a sporophyte that is unique from other hair-cap mosses. There is some confusion

Polypodium scouleri is a species of fern known by the common names leathery polypody, Scouler's polypody, coast polypody and leather-leaf fern. It is native to coastal western North America from British Columbia to Guadalupe Island off Baja California. It is a plant of the coastline, growing in cracks on coastal bluffs, in oceanside forests, beach dunes, and similar habitat. It is often affected by heavy fogs and sea spray. This polypody anchors with a waxy, scaly rhizome. It produces triangular or oblong leaves up to 85 centimeters (33 in) in maximum length and 8 cm (3.1 in) width. Each leaf
