Abstract

Liangpran Mountain is located within the Heart of Borneo (HoB) Conservation Area which has high biodiversity. The exploration of orchids has been carried out in several locations in the HoB region and recorded a high diversity of wild orchid. This research was conducted to explore and inventory the orchids from the foothill of Mount Liangpran, and record  the diversity and abundance of epiphytic orchids in the study sites. This research was carried out by making track of exploration along the Nuyung river estuary to the Tebing Lapah. The richness and abundance data were collected in three plot of 1000 x 20 m. The host tree characteristics and distribution of epiphytic orchid on the host tree were recorded. Fourteen species orchids were collected, and the most dominant are Coelogyne asperata and Agrostophyllum stipulatum with an abundance of 23.53% each. The epiphytic orchids in host trees are spread from the zone II to V based on the Johansson?s sections, in which zone IV is the most diverse. Nine species of the host trees associated with the collected orchids were identified and grouped into five families. The characters of host trees are 7?57 m height,12?112 cm diameters, and 2 types of bark surfaces (rough and intermediate).

Abstract

Suku Asteraceae merupakan suku dengan jumlah jenis tertinggi dan perawakan bervariasi. Sebanyak ± 30.000 jenis tersebar di dunia dan 150 marga diantaranya tersebar di kawasan Malesia. Jenis-jenis Asteraceae di Pulau Jawa tercatat dalam buku Flora of Java Jilid 2. Namun, dalam beberapa tahun terakhir terdapat beberapa jenis yang belum tercatat dalam Flora of Java telah ditemukan di Jawa. Penelitian ini bertujuan untuk mengungkap jenis tumbuhan rekaman baru untuk melengkapi penyusunan buku Alien Flora of Java. Penelitian ini dilakukan dengan metode jelajah pada Maret 2019 hingga Agustus 2020 di beberapa lokasi di Pulau Jawa. Terdapat satu jenis tumbuhan rekaman baru dari suku Asteraceae yakni Centratherum punctatum di Desa Galonggor Bogor dan Jatinangor yang telah ditemukan tumbuh meliar dan belum tercatat sebelumnya dalam Flora of Java. Jenis ini menambah data anggota Centratherum yang terdapat di Jawa. Pendugaan asal, penyebab meliar, pemanfaatan, serta kandungan kimia jenis ini dipaparkan di dalam tulisan.
