“…S. palustris is widespread in the lowlands overgrown by mangrove forests which have humid soil or aquatic habitats with relatively high conditions of light (Chambers 2013;Mildawati et al 2020). There are two species of Stenochlaena cultivated in the US, namely S. palustris and S. tenuifolia.…”

Abstract. Chotimah HENC, Muliansyah, Widyawati W, Pitrama, Suparto H. 2022. Species, nutritional value, and elemental content of Stenochlaena distributed in Central Kalimantan, Indonesia. Biodiversitas 23: 5367-5372. Stenochlaena J. Smith is belonging to the family of Blechnaceae, consisting of only seven species and widely distributed in tropical and subtropical regions. In Central Kalimantan Indonesia, Stenochlaena is also widely distributed and abundant in this province. The paper will deliver the diversity of species, and chemical composition value of Stenochlaena in Central Kalimantan. The method used was a survey conducted in the tree district of Central Kalimantan namely Barito Selatan, Kapuas, and Palangka Raya. The key to species determination used was a paper published by Chamber (2013). Chemical composition was measured by proximate analysis while elemental content was established by atomic absorption spectrophotometer. This is the first report on the proximate and element components of some Stenochlaena species, other than Stenochlaena palustris. The results showed that there were four species of Stenochlaena found in Central Kalimantan, namely Stenochlaena palustris, Stenochlaena tenuifolia, Stenochlaena milnei and Stenochlaena cumingi. Stenochlaena palustris had the greatest moisture and proteins while S. cumingii had the highest content of ash. The biggest content of lipids was owned by S. milnei meanwhile S. tenuifolia had the most content of fiber. Stenochlaena palustris also had the highest N, P, K, Mg meantime, the highest Ca and Fe were in S. cumingii and S. milnei, respectively.

“…Publications on the existence of Gleicheniaceae species were only available from studies on fern diversity in general, and not only focused on this family. The records on small number of Gleicheniaceae species were found from exploration studies in Enggano Island (Wardani and Adjie 2017), in Siberut National Park, West Sumatra (Mildawati et al 2020), in five mountains in West Java (Suryana et al 2020), and in Mount Gede Pangrango National Park, West Java (Andriyani and Nurza 2021). The objective of this study was to reveal the species diversity of the members of Gleicheniaceae in the Rokan Hulu, Riau.…”

Abstract. Marpaung AA, Susandarini R. 2021. Variation on morphology and spore characters of Dicranopteris and Sticherus (Gleicheniaceae) from Rokan Hulu District, Riau. Biodiversitas 22: 4475-4486. Dicranopteris and Sticherus are genera in the family Gleicheniaceae which have unique habits and distinctively specific growth with the presence of a bud on the forking branches. This study aims to reveal the species diversity of Gleicheniaceae members found in the forest area of Bukit Suligi Tandun, Rokan Hulu District, Riau and to document variations in their morphological characters and spores. Eleven collections were obtained from the exploration in the study area. The identification of plant specimens showed that these eleven taxa consisted of Dicranopteris curranii, Dicranopteris speciosa, seven varieties of Dicranopteris linearis, and two varieties of Sticherus truncatus. Seven varieties within D. linearis were D. linearis var. linearis, D. linearis var. alternans, D. linearis var. altissima, D. linearis var. demota, D. linearis var. inaequalis, D. linearis var. subspeciosa, and D. linearis var. tetraphylla. The only one species of Sticherus found was S. truncatus which consisted of two varieties, namely S. truncatus var. truncata and S. truncatus var. involuta. Morphological characters were observed from fertile specimens, while spore characters were observed from spore microscopic slides prepared using acetolysis method. There were 42 morphological characters and spores examined and used as the basis for determining the phenetic relationships using cluster analysis and principal component analysis. The results of cluster analysis showed the formation of two clusters that clearly separated the genus Sticherus from Dicranopteris. The three species of Dicranopteris were also clearly separated from each other in different sub-clusters. The result of principal component analysis indicated characters that contribute to the grouping of the eleven taxa and was able to explain the distinguishing characters in each group recognized from the cluster analysis. Overall, the results of this study contributed to documenting in detail the morphological variations in sporophyte and spore characters in eleven taxa of Dicranopetris and Sticherus, as well as proving the role of morphological and spore characters in the classification and defining phenetic relationships using numerical taxonomic approach.

“…Pteridophytes, a group of primitive vascular plants, has at least 13,600 species with geographical distribution all around the world [2]. This plant group has a wide and varied habitat, ranging from land, epiphytes and aquatic habitats in ecosystems ranging from coastal ecosystems to high mountain forests [3]. Pteridophytes have megaphylls (larve leaves), midribs and microfils (small leaves).…”

Polypodiaceae is one of the fern families by the highest number species and plays an important role in the ecosystem. The polypodiaceae family is also known for its pharmacological properties. The University of Sumatera Utara campus, as one of green spaces in Medan, has a various variety of plants from undergrowth to higher plants. However, no information on the diversity of Polypodiaceae epiphytic species on the USU campus has not been recorded. The aim of the research is to identify and evaluate the diversity of Polypodiaceae species on the USU campus. For those purpose an inventory method in all green spaces on the USU campus. Species identification was accomplished by morphological identification of founded epiphytes. The relative density and dominance values have been used to calculate species diversity (H'). The study revealed the presence of 6 (six) Polypodiaceae epiphytic species on the USU campus, namely Microsorum diversifolium, Microsorum pustulatum, Pyrrosia piloselloides, Phymatosorus scolopendria, Pyrrosia eleagnifolia and Pyrrosia lanceolate. The highest diversity index was found in Pyrossia piloselloides with an H' value of 0.345 and the lowest diversity was found in Microsorum pustulatum with an H' value of 0.001.
