Phaius spp orchid plant has a large enough plant size and dark and striking flower color which is an attraction for Phaius spp. Morphological characterization of orchids is needed for the preservation of germplasm and selecting a variety of natural orchid germplasm that has superior plant and hash suface properties to be used in crossing. The study used plant collection materials from the Bogor Botanical Gardens Conservation Center. (Sulawesi: Phaius tankervilliae, Phaius indigoferus, Papua: Phaius montanus, and Bali: Phaius amboinensis, Phaius callosus). This study aims to determine the genetic proximity to become parents in crossing.The morphological characterization method was carried out descriptively based on direct observation surveys and documentation of parts of natural orchid plants The study was conducted in May-August 2019 at the Bogor Botanical Gardens Conservation Center. The study was conducted on 20 characters with quantitative observations based on each orchid species (BALITHI 2007).
