During
a recent field survey in the Angul district of Odisha state, five species of
Pteridophytes were recorded for the first time, marking new additions to the
botanical inventory of the Odisha state. These species are Asplenium
yoshinagae Makino, Dryopteris carthusiana (Vill.) H.P.Fuchs, Lygodium
palmatum (Bernh.)Sw., Thelypteris kunthii (Desv.) C.V.Morton, Thelypteris
palustris Schott. The diagnostic features of each species are as follows:
Asplenium yoshinagae is characterized by its small, brown, narrowly
triangular and apically filiform scales on abaxial surface and pinna stalks.
Dryopteris carthusiana is identified by its Veins that extend into each
tooth are pinnate, simple, impressed adaxially, and elevated abaxially. Lygodium palmatum is characterized by its
long, creeping, slender rhizome and the presence of glandular, colorless or
brown-tinged hairs throughout the frond. Thelypteris kunthii is
characterized by its veins which is adaxially with similar hairs but blade
tissue usually without hairs. Thelypteris palustris is characterized by
its glabrous rachises, costae, and veins. This communication includes the
taxonomic descriptions, synonyms, ecological information, and photographs for
each of these newly recorded species.
