Study on Orchid Diversity in Gunung Simpang Nature Reserve, West Java
TL;DR: It was recorded that there were 137 orchid species belonging to 51 genera, 95species of which were epiphytes and 42 other species were terrestrial orchids, the most dominant terrestrial orchid was Plocoglottis javanica.
Abstract: Gunung Simpang Nature Reserve is located in West Java Province. It covers a 15.000 hectare area of highland forest, the altitude range between 800 to 1823 m asl. Orchid inventory and exploration were conducted to study orchid diversity in this conservation areas. Living plant was collected for ex situ conservation purpose in Botanic Garden. Observation on the population of terrestrial and epiphyte orchid was also done to study the dominant orchid in that area. It was recorded that there were 137 orchid species belonging to 51 genera, 95species of which were epiphytes and 42 other species were terrestrial orchids. 134 species of which were collected in Cibodas Botanic Garden, which is suitable place for highland plant. The most dominant terrestrial orchid was Plocoglottis javanica. Other species were also abundantly found, such as Phaius pauciflorus, Liparis rheedii, Diglyphosa latifolia, Neuwiedia zollingeri var. javanica, Calanthe ceciliae, C. speciosa and Phaius callosus. Some epiphyte orchids were very common found, that are Agrostophyllum majus, Coelogyne speciosa, Dendrobium mutabile, Agrostophyllum bicuspidatum, Pholidota ventricosa and Eria javanica. Some attractive orchids are potential for ornamental plant, such as Vanda tricolor, Phaius callosus, Phaius tankervilleae, Arundina graminifolia, Bulbophyllum lobbii, Coelogyne speciosa, Calanthe ceciliae, Calanthe triplicata and Calanthe speciosa.© 2005 Jurusan Biologi FMIPA UNS SurakartaKeywords: orchid, Gunung Simpang Nature Reserve, diversity.

TL;DR: To inventory orchid’s species in Lamedai Nature Reserve, Kolaka, Southeast Sulawesi by explorative method, the result showed that there were 27 orchids species, consist of, 25 species (16 genera) epiphytic orchid and 2 species terrestrial orchid.
Abstract: Lestari DA, Santoso W (2011) Inventory and habitat study of orchids species in Lamedai Nature Reserve, Kolaka, Southeast Sulawesi. Biodiversitas 12: 28-33. Orchid is one of the ornamental plants which have been high commercial value. Therefore, orchid often has been over exploitation. Finally, some of orchid species are becoming threatened or even endangered. Purwodadi Botanical Garden as an institute of ex-situ conservation play role with it. The aim of this research is to inventory orchid’s species in Lamedai Nature Reserve, Kolaka, Southeast Sulawesi by explorative method. Observation for habitat study was focused on some ecological factors supported to orchids growth like host tree, zone growth on host tree, abundance of sunlight, thickness of substrate (moss), orchid species and number of individual species. The result showed that there were 27 orchids species, consist of, 25 species (16 genera) epiphytic orchid and 2 species terrestrial orchid such as Eulophia keithii var. celebica and Goodyera rubicunda (Blume) Lindl. The host preference for theepiphytic orchid is the group of Myrtaceae family like Syzygium sp., Metrosideros vera Niederen and Metrosideros sp. They mostly grow on the main stem of the tree zone 1 on thick substrate (moss) and get a little abundance of sunlight (calm).

TL;DR: The results showed that there were 29 epiphytic orchid species recorded, and Zone 3 (bottom part of the branches) was revealed as the most favorable part at the host tree (281 individuals), while Zone 1 (bottom parts of the main stem) was the least preferable one.
Abstract: Yulia ND, Budiharta S (2011). Epiphytic orchids and host trees diversity at Gunung Manyutan Forest Reserve, Wilis Mountain, Ponorogo, East Java. Biodiversitas 12: 22-27. Natural forests in Wilis Mountain have been destroyed by forest fires, landslides and illegal logging. As a consequence, biological diversity in this area is threatened by local extinctions, particularly of orchid species. This study was aimed to explore, document and analyze the diversity of epiphytic orchids at Gunung Manyutan Forest Reserve, a natural forest area in Wilis Mountain. Purposive sampling on 1 hectare (50 x 200 m2) eight subplots (25 x 50 m2) All data on orchid species were recorded including its number, host trees and zone of the host tree where the orchid attached. The results showed that there were 29 epiphytic orchid species recorded. Flickingeria angulata was the most abundant species (Relative Abundance of orchids/ %Fo = 38.74), continued by Appendicula sp. (%Fo = 10.91) and Eria hyacinthoides (%Fo=6.57). The three most important host trees were Pinus merkusii, Schima wallichii and Engelhardia spicata. Zone 3 (bottom part of the branches) was revealed as the most favorable part at the host tree (281 individuals), while Zone 1 (bottom part of the main stem) was the least preferable one.

TL;DR: The results show that based on the morphological characterization of the five species of Phaius spp.
Abstract: Hartati S, Samanhudi, Manurung IR, Cahyono O 2021 Morphological characteristics of Phaius spp orchids from Indonesia Biodiversitas 22: 1991-1995 Orchid is one of the ornamental plants with great economic value in various communities Characterization and grouping of several orchid species can be used in breeding efforts to obtain hybrid with the desired traits This study is aimed to characterize the morphological appearance of Phaius orchids and to cluster the species based on their similarity in morphological characteristics Five species of Phaius (P tankervilleae, P indigoferus, P montanus, P amboinensis, and P callosus) of the collection of the Bogor Botanical Garden were observed based on 30 morphological characters including the characters of stems, pseudobulbs, leaves and flowers The data obtained were converted into binary data and computed using the Numerical Taxonomy and Multivariate Analysis System (NTSYS) Spc 202 program to produce dendrogram The results show that based on the morphological characterization of the five species of Phaius spp, they have similarities from 63% to 80% Among the five Phaius species, P amboinensis, P tankervilleae, and P montanus had 80% similarity and can be used as parents for crossing

TL;DR: In this article, the diversity of orchids at the Ngebel - Ponorogo RPH area, precisely in the Ringin Putih and Gunung Picis Forest Reserve was done.
Abstract: The research on the diversity of orchids at the Ngebel - Ponorogo RPH area, precisely in the Ringin Putih and Gunung Picis Forest Reserve was done. The results showed that there were 20 orchid species were consisting of 15 epiphytic orchids that belonged to 10 genera and 5 terrestrial orchids that belonged to 5 genera. Epiphytic orchids found in the area grow on host trees such as Coffea trees, Ficus and Litsea.
