“…Sledge 1972: 422), Podopeltis (T. singaporiana) and Hemigramma (T. harlandii) all have the more or less anastomosing veins that form copious areoles typical of many Tectaria. Holttum (1988) did not recognize Hemigramma as a natural group, but showed that its species are similar to Tectaria. The condition of leaf dimorphism has arisen many times in ferns, in Tectaria alone at least eight times according to the results of our phylogenetic analysis.…”

The fern genus Tectaria has generally been placed in the family Tectariaceae or in subfamily Tectarioideae (placed in Dennstaedtiaceae, Dryopteridaceae or Polypodiaceae), both of which have been variously circumscribed in the past. Here we study for the first time the phylogenetic relationships of the associated genera Hypoderris (endemic to the Caribbean), Cionidium (endemic to New Caledonia) and Pseudotectaria (endemic to Madagascar and Comoros) using DNA sequence data. Based on a broad sampling of 72 species of eupolypods I (= Polypodiaceae sensu lato) and three plastid DNA regions (atpA, rbcL and the trnL-F intergenic spacer) we were able to place the three previously unsampled genera. Our results show that Cionidium, like Ctenitopsis, Fadyenia, Hemigramma and Quercifilix, is embedded in Tectaria, and the monophyly of Tectaria is therefore corroborated only if these segregate genera are included. Hypoderris is sister to Tectaria brauniana and together they are sister to Triplophyllum, which was found to be monophyletic. Despite their morphological similarity with Tectaria, the genera Pleocnemia and Pseudotectaria were placed in Dryopteridoideae. Polypodiaceae subfamily Tectarioideae (former family Tectariaceae) is hereby defined to include Arthropteris, Hypoderris, Pteridrys, Tectaria and Triplophyllum. Aenigmopteris may also belong here, but this genus remains unsampled.

“…However, to date T. fuscipes has not been recorded in Japan. This species is also reported in India and most Southeast Asian countries: Cambodia, Indonesia, Myanmar, Nepal, Taiwan, Thailand, Vietnam (Ching, 1931;Holttum, 1988;Wu et al, 2013;Patil et al, 2014;Sun et al, 2014). In previous studies, the easternmost and northernmost distribution of the species was known to be Taiwan and Xizang, respectively.…”

Tectaria fuscipes (Wall. ex Bedd.) C. Chr. (Baek-Rok-Go-Sa-Ri) is newly reported in Korea. This species belongs to the genus Tectaria Cav. of the family Tectariaceae Panigrahi. Thus far, no taxa of Tectariaceae have been reported in Korea. Tectaria fuscipes is characterized by its suberect to ascending rhizome, dimorphic or subdimorphic fronds, and free veins. The species was found on the southwestern slopes of Mt. Halla on Jeju Island, where it grows in sun near a small cave. It also occurs in southern China and in Taiwan. In Japan, eight species of the genus Tectaria have been reported, but T. fuscipes has yet to be recorded there. Jeju Island is the northeastern-most limit of the known range of this species.

“…It is also noticed that there are no scales above the base of stipes in this species. Scaly stipes, previously considered a diagnostic character of T. griffithii (e.g., Holttum 1988, Tagawa & Iwatsuki 1988, Wang 1999 Note:-As stated above, Tectaria multicaudata is a separate species from T. griffithii. They are distinct in the venation pattern, i.e., costal and costular areoles are present in T. multicaudata but absent in T. griffithii (Fig.…”

“…Unfortunately, later authors ignored the easily recognizable difference of venation between the two species. It is notable that the venation in such two conditions (costal areoles present or not) is the sole difference between two sections of Tectaria proposed by Holttum (1988Holttum ( , 1991a. According to Holttum's subdivision of Tectaria, T. multicaudata should be grouped into sect.…”

The misapplication of the name Tectaria griffithii is corrected, which results in the revival of T. multicaudata and the proposal of a new combination (T. multicaudata var. amplissima) and two new synonyms (T. yunnanensis and T. multicaudata var. singaporeana). For the reduction of Psomiocarpa and Tectaridium (previously monotypic genera) into Tectaria, T. macleanii (new combination) and T. psomiocarpa (new name) are proposed as new combinations. In addition, the new name Tectaria subvariolosa is put forward to replace a later homonym (T. stenosemioides).
