A New Record Mycoheterotrophic Plant in Bukit Barisan Grand Forest Park, North Sumatra, Indonesia

Mycoheterotrophic plants are unique plants because these plants do not have leaves (chlorophyll) and get their nutrients from a symbiotic relationship with fungi. In some recent literature, Mycoheterotrophic can be also called holomycotrophic plants. The purpose of this study was to determine the mycoheterotrophic plant species in the Bukit Barisan Grand Forest Park, North Sumatra. The purpose of this research is to know the type of mycoheterotrophic plant in Bukit Barisan Grand Forest Park, North Sumatra, Indonesia. This research was conducted in August 2019 in Bukit Barisan Grand Forest Park, North Sumatra, Indonesia. In conducting plant sampling the method used is the exploration or roaming method. Identification of mycoheterotrophic plants based on morphological characteristics in the form of habitus, stems, flowers, roots and matched using literature then lists the species of mycoheterotrophic plants presented in this study consisting of scientific names, synonyms, descriptions, distributions, ecological information. The results of field exploration found 3 species in two mycoheterotrophic plant families, Burmaniaceae and Orchidaceae. The Burmaniaceae family consists of 1 type of Burmannia lutescens Becc. While the Orchidaceae family consists of two species, among others, the Epipogium roseum (D. Don) Lindl. and Gastrodia siamensis Rolfe ex Downie. 3 mycoheterotrophic plants became a new record for the Forest Park of Bukit Barisan Sumatra Utara because previously there was no data on the plant.
