“…Cyathea spp. have become a high priority focus for many scientists (Lehnert et al 2019) because these ancient and conspicuous plants are listed as endangered in the index of CITES (CITES 2019) to restrict and control their trade. In Indonesia and other countries, such as in Colombia (Eleuterio and Perez-Salicrup 2006), the trunks of Cyatheaceae with their fibrous root mantle are locally used for substrates for epiphytic plants, making special flowerpots, and other crafts.…”

Abstract. Hasanah U, Hadisunarso, Praptosuwiryo TN. 2021. Composition, community structure, and vertical distribution of epiphytic ferns on Cyathea junghuhniana in Gede-Pangrango National Park, Indonesia. Biodiversitas 22: 4968-4976. Epiphytic ferns are a significant component of tropical forests worldwide and contribute significantly to the high species diversity found in tropical regions. Tree ferns are important phorophytes for the establishment and occurrence of epiphytic fern species in tropical forests. The first detailed description of the diversity and abundance of epiphytic ferns on the tree fern Cyathea junghuhniana (Kunze) Copel. in a natural forest of Indonesia is provided. This study aimed to determine the species composition, richness, abundance, community structure, and vertical distribution of epiphytic ferns growing on the tree fern C. junghuhniana in the mountain forest of Gede-Pangrango National Park, West Java, Indonesia. The 35 tree fern caudices of at least 3 m height were selected by purposive random sampling. Each tree fern was divided into intervals of 1 meter from ground level to a height of three meters, thus obtaining 105 one-meter samples of the epiphytic fern community on tree fern caudices stratified according to height. The Importance Value Index (IVI) was estimated for each species of epiphyte based on the frequency of occurrence on caudices. The 35 tree fern caudices hosted 760 fern epiphytes belonging to 12 species of 9 genera and 6 families. The highest species richness occurred in Polypodiaceae. The species with the highest Importance Value Index (IVI = 1.24 %) was Nephrolepis davallioides (Sw.) Kunze, with increasing frequency from bottom to top of the caudex.

In Indochina the species diversity of Cyatheaceae remains insufficiently known. Here we demonstrate the scaly tree fern Gymnosphaera salletii in Vietnam to be an assemblage of three distinct species based on molecular and morphological data, and report for the first time the occurrence of foliar nectaries in Gymnosphaera. The true G. salletii is morphologically unique based on the protuberant glands present on the petiole. Gymnosphaera phankelocii sp. nov. and Gymnosphaeravietnamensis sp. nov. are recognized as new species; G. phankelocii is characterized by its distant two-rowed sori and G. vietnamensis by the sub-tripinnate fronds. Our phylogenetic analyses indicated that G. phankelocii is a relatively isolated species, while G. vietnamensis is a member of the G. salletii clade along with G. austroyunnanensis, G. salletii, and G. saxicola. The two new species and members of the G. salletii clade are all local endemics, and provide good examples to understand the frequent local endemics and their evolution in scaly tree ferns. Eleven species of Gymnosphaera are now known from Indochina; we provide a diagnostic key to these species.
