Komposisi Anggrek Tanah Dan Vegetasi Lantai Hutan Di Jalur Pendakian Utama Gunung Andong, Magelang, Jawa Tengah

Due to the risk ofwildtype orchids extinction, studies on the diversity of orchid species are important. Generally, floral checklist can be used to describe plant diversity such as terrestrial orchid species and forest floor vegetation.This research was aimed to know terrestrial orchid species & forest floor vegetation at Gunung Andong, Magelang, Jawa Tengah. Field research was done by exploration method using purpossive sampling at main tracking route of Gunung Andong and data analysis was calculated based on vegetation parameters i.e. plant density and frequency. The result showed that there are 24 species of terrestrial plants belongs to 4 subfamilia: Orchidoideae, Epidendroideae, Cypripedioideae, and Spiranthoideae. Also, this research has found 52 species of 24 familia of forest floor vegetation. Based on the composition of terrestrial orchids and forest floor vegetation, we assume that the plant diversity at Gunung Andong, Magelang, Jawa Tengah is relatively high and routine monitoring is needed

Phytochemical Survey of Orchids in the Tirunelveli Hills of South India

Phytochemical investigations of the orchid family were performed for alkaloid constituents, identification and inheritance of flower pigments in the species of ornamental value. Apart from the presence of chlorophyll in green flowered forms and carotenoids in some yellow flowers, anthocyanidins are predominated. The cyaniding, pelargonidin and petunidin, and complex mixture of their glycosides and acylated derivatives are often present in a single flower. In the present investigation of the preliminary phytochemical study of leaf flavanoids contents of Orchidiaceae family members in the Tirunelveli hills of South India were analyzed and surveyed

Cities and Disturbed Areas as Man-made Shelters for Orchid Communities

Many species from the family Orchidaceae spread in anthropogenic habitats and numerous studies documenting this process are known. Unfortunately, such data are scattered throughout various papers and reports, sometimes fragmentary and hard to reach (the ‘grey literature’). Scientific elaboration on this topic still lacks a comprehensive review and summary of the scale of this phenomenon. Therefore, the main aim of this study was to gather, review and analyse such data, seeking the answer to the question whether the man-made habitats can be considered as refugee for orchids. The paper summarises data on the occurrence of orchid species in man-made habitats in Europe originating from published and unpublished sources. The particular emphasis was placed in urban habitats. For this purpose, the floristically data from 42 European cities were used. The conducted studies showed that the apohytism phenomenon in the family Orchidaceae was more widespread than had been previously reported. As a result, 70 species of orchids in the distinguished man-made habitats were found. The majority of the species grow on sand and clay pits. The most common species were Epipactis helleborine and Dactylorhiza majalis. The gathered data have confirmed that man-made habitats become refugee for many orchid species in the aftermath of the loss of their natural habitats. Thus, protection of sites transformed by man with orchid occurrence should be taken into consideration. These sites can become a source of very useful information for biogeographically and phylo-geographically analyses of many valuable and endangered species

A constituição e organização anatômica dos órgãos vegetativos de Goodyerinae neotropicais são muito semelhantes, havendo pouca variação entre as espécies, deste modo são apresentadas: a descrição anatômica caracterizando os órgãos vegetativos da subtribo, pranchas fotográficas dos cortes anatômicos, bem como são discutidos os resultados encontrados

Documentation of ethnomedicinal orchids from Jammu and Kashmir, India

Orchids are a group of plants famous for their showy and beautiful flowers. Besides their aesthetic value, these are also used traditionally for their ethnomedicinal properties. In Jammu and Kashmir, India, 21 orchid species from 17 different genera have been documented for their utilization as ethnomedicinal plants. Rhizomes and tubers of these orchids are the main plant parts to be used to cure many disorders like gastro-intestinal, skeleton-muscular, neurological and others

Molecular characterization and phylogenetic relationships among and within species of Phalaenopsis (Epidendroideae: Orchidaceae) based on RAPD analysis

Random amplified polymorphic DNA (RAPD) analysis for 20 species of Phalaenopsis was conducted to determine their genetic distances and relationships. Among 20 different primers used for RAPD analysis, 10 primers showed polymorphism, and according to the primer type, 26 to 54 DNA fragments were amplified. A total of 414 polymorphic fragments were generated by 10 primers and used for correlation group analysis. The highest value of Similarity index was 0.28 between Ph. violacea malaysia and Ph. violacea witte. The dendrogram resulting from UPGMA (Unweighted Pair Group Method using Arithmetic average) hierarchical cluster analysis separated the original species into three groups: The first group had five species of Ph. violacea blue, Ph. belina, Ph. violacea malaysia, Ph. violacea witte, and Ph. gigantea; the second group included Ph. lamelligera, Ph. amabilis, Ph. parishii, Ph. labbi nepal, Ph. speciosa, Ph. lobbi yellow, Ph. venosa, Ph. hieroglyphica, and Ph. maculata; the third group consisted of Ph. minho princess, Ph. leopard prince, Ph. mannii, Ph. modesta, Ph. cornucervi and Ph. pantherina. RAPD markers can thus be successfully applied in this economically important group of orchids for the study of molecular characterization and relationships. The data acquired from this study could be used for identification and classification of other orchid genera and oriental Phalaenopsis

Floristic studies on some rare plants in Western Ghats of Nasik District, M. S.

The present study deals with taxonomical aspects along with the observation regarding threats, flowering and fruiting period, precise locations of some rare plants of Western Ghats in Nasik District of Maharashtra. Extensive field visits and botanical excursions were conducted during period of investigation i. e. from 2013-2019 in and around the forest area of Nashik district. The major areas that were explored during study are mainly forest pockets and hills regions of Trimbakeshwar, Brahmhagiri mountains, Anjaneri hills, Adwadi hills, Sinnar and environs hilly ranges, Kelzar hilly areas, Mulher, Salher, etc. During the study: more than 150 species of rare plants belonging to 46 families were recorded. The probable reasons that were observe from the decrease of rare plant species population are destruction of natural habitats due to increasing illegal acquiring of forest land, massive deforestation and rapid urbanization. Also, ex-situ conservation of some plant species within the college botanical garden was attempted. However: the present study highlights an effective and purposeful conservation strategy to be adopted for the sustainable use and conservation of important rare plants in the region

Inventorying medicinal orchid in Indonesia from global database

The global database plays an important role in preserving vital data and information that aids in the conservation and sustainable use of organisms, including plant species. Many data related to Orchidaceae as one of the largest families of flowering plant species are stored in global databases. An inventory study was done on the medicinal orchid species distributed in Indonesia from several global databases. This study aimed to acquire data from several global databases (i.e., POWO, MPNS, and IUCN REDLIST) related to what and where species are distributed in Indonesia, which species have medicinal records, and other information supporting conservation and sustainable use. The result showed six thousand orchid species with 200 genera in Indonesia. Bulbophyllum, Dendrobium, and Crepidium are the top five biggest genera. More than five thousand orchid species are endemic and distributed mainly in Papua, Kalimantan, and Jawa. About 130 orchid species have medicinal use; 115 orchid species are documented as medicinal plants worldwide, including 39 species recorded in Indonesia. IUCN Redlist has assessed 430 species, with 87 species included in IUCN Redlist species; one medicinal species listed as endangered species (Vanilla planifolia Andrews); and five species assessed as least concerned species. These findings could be important as a foundation for future conservation and sustainable use studies, not only in Indonesia but also in the world
