Asplenium is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider Hymenasplenium separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is Asplenium marinum.
Myosotis is a genus of flowering plants in the family Boraginaceae. The name comes from the Ancient Greek μυοσωτίς "mouse's ear", which the foliage is thought to resemble. In the Northern Hemisphere, they are colloquially known as forget-me-nots or scorpion grasses. Myosotis alpestris is the official flower of Alaska and Dalsland, Sweden. Plants of the genus are not to be confused with Chatham Islands' forget-me-nots, which belong to the related genus Myosotidium.
Adenophorus is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is endemic to Hawaii.
Pladaroxylon is a genus of trees in the tribe Senecioneae within the family Asteraceae.
The flora of Saint Helena, an isolated island in the South Atlantic Ocean, is exceptional in its high level of endemism and the severe threats facing the survival of the flora. In phytogeography, it is in the phytochorion St. Helena and Ascension Region of the African Subkingdom, in the Paleotropical Kingdom.
Mellissia was formerly a monotypic genus in the family Solanaceae with the single species, Mellissia begoniifolia, endemic to the island of Saint Helena.

The Leptopteris is a small genus of ferns native to the New Guinea, Australia, New Zealand, and the Pacific Islands. They are similar to ferns in the related genus Todea, and were originally included in that genus. However, the very thin fronds of Leptopteris differ from the thick leathery fronds of Todea, and the genera are considered distinct. A probable extinct species, Leptopteris estipularis is known from the Early Cretaceous of India.
Didymoglossum is a tropical genus of ferns in the family Hymenophyllaceae. It comprises more than 30 epilithic or low-epiphytic species under two subgenera. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016, but not by some other sources which sink it into a broadly defined Trichomanes.
Bosea cypria is a species of flowering plant in the Amaranthaceae family. It is a highly branched, evergreen shrub, 1–2 m high, erect, suberect, or hanging on walls, cliffs or trees, with hairless angular shoots.
