Nypa palm (Nypa fruticans Wurmb.) is a kind of palm growing very well in the brackish water forest or along the river near its mouth. In some countries, it is considered to be invasive plant, so that its development should be controlled. The aim of this study is to find out the morphological distribution of the nypa along Cilacap and Kebumen coastal areas of Central Java. The method used in this study is survey. The sample was taken with purposive sampling technique by taking samples from nypa population randomly. The environmental factors measured included water salinity, water pH, soil pH, and soil type. The nypa characteristics measured included leaf morphology and size, and plant individual density. The results of this study based on the distance from the coastline showed that: 1) The nypa is mainly distributed along the river with Grey regosol and Alluvial Hydromorph soils; 2) erect leafed nypa are present close to the water while the curved leafed nypa were presence in the inner part of the areas; 3) Based on the rachis color, the young, medium, and old nypa leaves tend to have green, greenish yellow, and orange rachis respectively. 4) Based on survivability, the nypa seeds tend survive in water further inland.
Lansium parasiticum (Duku) is a plant species with complex morphological characters because of its wide distribution. This study examined the plant anatomical variation patterns and phenetic relationships among 15 local duku samples from Purwokerto, Purbalingga, and Banjarnegara. The anatomical data were analyzed descriptively, and the similarity relationship was measured with the UPGMA method using the MEGA 10.0.1 software. The results of anatomical characters analysis suggested a high degree of diversity among the duku. UPGMA tree derived from cluster analysis showed two majors clusters. The first cluster consisted of samples whose upper epidermis thickness was ⩾16.5µm. The second cluster comprised fourteen samples with upper epidermis thickness <16µm.
Acanthus is the only genus of family Acanthaceae which occupies mangroves habitat. Despite the importance of Acanthus, collection, characterization and improvement of its germplasm is limited. Hence, this will hinder its effective conservation and utilization. Therefore, the objective of this research was to identify morphological variation of Acanthus in some estuarine areas of Cilacap Central java in relation to habitat. The method used in this study was survey with stratified sampling. The variables measured included, leaf shape, size, apex, base, margin, color and spine. The results of this study indicated that the different location affect some morphological characteristics. Most of the Acanthus population observed in this study have direction of stem axial spines facing upwards, green, inflorescences spika, petals large, light violet Similar to characters Acanthus ilicifolius has variations in leaf margin, leaf shape and size.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
