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.

Ophioglossum, the adder's-tongue ferns, is a genus of about 50 species of ferns in the family Ophioglossaceae. The name Ophioglossum comes from the Greek meaning "snake-tongue". [ 3 ] Their cosmopolitan distribution is mainly in tropical and subtropical habitats .
Below are lists of extant fern families and subfamilies using the classification scheme proposed by the Pteridophyte Phylogeny Group in 2016 (PPG I). [1] The scheme is based on molecular phylogenetic studies, and also draws on earlier classifications, [1] particularly those by Smith et al. (2006), [2] Chase and Reveal (2009), [3] and Christenhusz et al. (2011). [4]
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.

Ophioglossum lusitanicum is a small winter annual fern, and consists of a simple sterile blade attached to a spike-like fertile blade with between three and eight sunken sporangia on either side. The whole plant rarely exceeds a height of 2 cm. [4] This species has a chromosome number of 2n = 250–260. [4]
