The most striking and unusual feature of the fern is its simple, strap-shaped undivided fronds. The supposed resemblance of the leaves to the tongue of a hart (an archaic term for a male red deer) gave rise to the common name "hart's-tongue fern". Asplenium scolopendrium. Asplenium scolopendrium sori. Asplenium scolopendrium prothallus
Protea scolopendriifolia, also known as the harts-tongue-fern sugarbush [2] or hart's-tongue-fern sugarbush, [3] is a flowering shrub endemic to South Africa, where it occurs in both the Western and Eastern Cape. [2] It is found from the Cederberg, through the Kogelberg, Riviersonderend Mountains and Swartberg, to the Kouga Mountains.

Larvae feed from August to June, initially in a whitish mine in the frond, and in the spring they leave the mine and burrow into a sorus, feeding on the sporangia.They later form a loose, portable case from empty sporangia and when fully grown in May the case resembles a misplaced sorus, especially on hart's-tongue fern (Asplenium scolopendrium).
Both the scientific name and the common name "spleenwort" are derived from an old belief, based on the doctrine of signatures, that the fern was useful for ailments of the spleen, [4] due to the spleen-shaped sori on the backs of the fronds. "-wort" is an ancient English term that simply means "plant" (compare German-wurz).
Another, between A. pinnatifidum and the tetraploid American hart's-tongue fern (A. scolopendrium var. americanum) yielded peculiar specimens with a long blade, similar in texture and doubled indusia to the hart's-tongue fern, but lengthened and tapering to a point, and not lobed except for two surprisingly large auricles at the base.

The name was derived from the species' characteristic small, blistered (risen) sori on its abaxial surface (micro = small, sorum = from sori, pustulatum= blistered). [10] In 2019 the species was renamed Zealandia pustulata by Testo & A.R.Field. As of September 2024, Plants of the World Online uses the name Lecanopteris pustulata. The species ...
