“…The main feature of Paphiopedilum is its pouch-like lip on the flower (Romadlon et al 2021). While the diagnostic characters of P. javanicum are the presence of mottled leaves, with darker green spots superimposed over a light green background; the dorsal sepal is ovate, acute, green with white margins, longitudinally striped dark brown; petals long-oblong, held nearly horizontal but sometimes dropping, greenish finely spotted reddish-brown in the lower two-thirds, white or pink in the apical third; and the dull lip brownish-green (Comber 1990;Hendriyani et al 2019) The second sub-family in this study is Orchidoideae, a group of orchids that grow as terrestrial with erect inflorescences. Sub-family Orchidoideae shows several diagnostic characters such as their life form as terrestrial, the growing from tubers or a horizontal fleshy rhizome; anther basifixed or not; pollinia segmented, comprising massulae, or mealy .…”

Abstract. Kurniawan FH, Nazar L, Anjarwati R, Sasono HD, Rahayuningsih M. 2021. Orchids of Mount Ungaran (Indonesia) compiled from a decade of data collections between 2010 and 2021. Nusantara Bioscience 13: 245-259. Orchid is well known as a plant group widely used as ornamental plants because of their uniqueness. But, high exploitation, deforestation, and land-use changes have threatened orchid species and triggered extinction. It also happened in Mount Ungaran, Central Java, Indonesia, despite designation as an essential ecosystem area. This research was conducted to add an updated list of wild orchid species that can serve as biodiversity baseline data for conservation management in Mount Ungaran. The study was carried out through exploration activities from 2010 to 2021. The study area covered eleven sites namely Gentong Hills, Kalisidi, Pasigitan, Banyuwindu, Gajahmungkur, Watuondo, Mawar Camp, Indrakila, Gondang and Puncak which were all included in the buffer zone of Mount Ungaran. A total of 115 species from 54 genera of orchids were successfully identified, including 78 species of epiphyte and 37 species of terrestrial orchids. Among the species recorded, at least 27 species were known to be endemic to Indonesia, and 8 species were endemic to the island of Java, which four species were listed in the IUCN Red List. In addition, all the species found were listed in Appendix II of the CITES, except one species, Paphiopedilum javanicum which was listed in Appendix I. This study recorded the new distribution records of several species of orchids that were previously only found in West Java or East Java, i.e., Ania penangiana, Pholidota convallariae, and Crepidium junghuhnii. This study has also documented a species from genus Crepidium, which morphological characters have not been described in any identification guides. The Gentong area has potential as a priority for in-situ orchid protection area by the highest number of species were reached 54% of all orchids found on Mount Ungaran.
