Prosaptia contigua C. Presl (Grammitidaceae), a New Record for Vietnam

The specimens of the genus Prosaptia C. Presl (family Grammitidaceae) stored in the Herbarium of VNU University of Science (HNU) were studied. Traditional morphological methods are used to study the specimens. The result provides descriptions, illustrations and comparisons of 6 species that listed of the genus Prosaptia follow as: P. alata, P. barathrophylla, P. intermedia, P. pectinata, P. obliquata and P. contigua. Prosaptia contigua (G. Forst.) C. Presl has been determined as a new record for the flora of Vietnam.

Taxonomic novelties in grammitid ferns (Polypodiaceae) from the Neotropics and Madagascar supported by molecular data

Based on cpDNA data, we provide the phylogenetic position for 18 species of Neotropical grammitid ferns (Polypodiaceae) that were not previously included in a molecular phylogeny. These species were resolved in Alansmia, Ceradenia, Enterosora, Grammitis, Lellingeria, Lomaphlebia, Melpomene, Moranopteris, Stenogrammitis, and Terpsichore. Our results indicate that Enterosora is polyphyletic and in need of generic recircumscription. We maintain the identity of Enterosora, based on the position of E. campbellii subsp. spongiosa, a variety of the type species. This finding allowed us to conclude that the E. parietina clade should be excluded from Enterosora. To accommodate this clade we describe a new genus, Parrisia. It is related to Adenophorus and a clade that includes Cochlidium, Grammitis s.s., and Lomaphlebia. We further found that Zygophlebia is paraphyletic with respect to Enterosora, represented by two separate clades, Zygophlebia s. s. that includes Z. cornuta, the type species, Z. sectifrons and Z. matthewsii, and a second clade that includes another seven species of Zygophlebia as well as E. barbatula. As a separate clade, this Zygophlebia species could be maintained. However, we prefer to sink both Zygophlebia clades into Enterosora. We propose ten novel combinations for Enterosora, by moving Zygophlebia with a confirmed phylogenetic position to Enterosora. It is possible that the remaining Zygophlebia species should also be treated as Enterosora, but further research is necessary.

The Flora Malesiana Account of Grammitid Ferns (Polypodiaceae)

Fourteen genera and approximately 373 species of grammitid ferns (formerly Grammitidaceae, now Polypodiaceae) occur in Malesia. The Flora Malesiana account of the group is 75% complete (280 species). The genera are illustrated and briefly described. Current studies involve working through species that have long been herbarium dumping grounds containing numerous undescribed species, such as Calymmodon cucullatus (Nees & Blume) C.Presl, Prosaptia contigua (G.Forst.) C.Presl, Radiogrammitis hirtella (Blume) Parris (as Grammitis hirtella) and Tomophyllum subfalcatum (Blume) Parris (as Ctenopteris subfalcata).

New species and records of grammitid ferns (Polypodiaceae) for Vietnam

Three new species (Calymmodon concinnus, Oreogrammitis parvula, Xiphopterella parva), and seven new records (Dasygrammitis brevivenosa, Oreogrammitis sinohirtella, Radiogrammitis beddomeana, R. jagoriana, Scleroglossum pyxidatum, S. sulcatum and Themelium halconense) of grammitid ferns (Polypodiaceae) are reported for the flora of Vietnam, mostly from newly collected specimens. We provide detailed morphological descriptions, illustrations, ecology and distribution, and taxonomic notes for each new species. Furthermore, type information, distribution, voucher specimens and taxonomic notes are provided for each newly recorded species. A checklist including synonymy and a key to Vietnamese grammitid ferns are also given.
