Abstract

Campus of  Sriwijaya University in Indralaya , has a high diversity of flora including fern, especially the epiphytic ferns, whose existence is so widely found in oil palm plants.  Survey about  diversity of this epiphytic has been carried out  from July to November 2017, with aim to identifying the diversity of species of epiphytic ferns in oil palm plants on the campus of UNSRI Indralaya. The research method used is exploration method with direct collection technique from the field and then made herbarium. A total of 27 species of pteridophytes were collected from the study area. Floristic analysis of collected specimens was carried out to find out the families, genus and species. In this survey was  collected 27 species belonged to13 genera, 7 families such  Aspleniaceae, Blechnaceae, Davalliaceae, Lygodiaceae, Nephrolepidaceae, Polypodiaceae, and Vittariaceae. The most common types are Polypodiaceae is Drynaria quercifolia, Drynaria sparsisora, Microsorum pustulatum, Microsorum punctatum, Phymatosorus scolopendria, Polypodium verrucosum, Polypodium polysthicum,  Pyrrosia piloselloides, and Goniophlebium verrucossum. The most widely distributed species in oil palm is Davallia denticulata , Goniophlebium verrucosum, and Nephrolepis biserrata.

Abstract

This study is aimed to recognise the morphological characteristics of Nepenthes mirabilis and Nepenthes gracilis in peat swamp area including stem, leaf, tendril, pitcher, flower, fruit, and seed.  This study has been conducted in January  until April 2018, located in Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir, South Sumatera. This study uses an exploratory method and the the observation sample using the method of random plot is chosen by purposive sampling. Parameters observed morphological characteristics of Nepenthes include stems, leaves, tendrils, pitcher, flower, adn fruit, as well as measurement of environmental factors. Based on the study, the researcher obtained two types of Nepenthes which are Nepenthes mirabilis and Nepenthes gracilis in  peat swamp area of Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir. Nepenthes mirabilis has a teres stem, leaves that in the form of oblong to lanceolate, has a petiolate, the edge of the leaves is flat covered by smoothy hair, thick peristome in size of 0,4-0,5 cm. Meanwhile stem Nepenthes gracilis has triangular stem, leaves in formed of lanceolate, sessile, flat edge of leaves, thin peristome in size of 0,1-0,2 cm. The pitcher shape of Nepenthes mirabilis and Nepenthes gracilis are cylindrical, infundibulate, and waist. The flower of Nepenthes mirabilis and Nepenthes gracilis are compound in type of  raceme inflorescences. The fruit is formed as capsula, has four lobed, and contains numerous seeds. The seed is spindle-like and white colored.
