Abstract
Geodorum is a small distinctive genus with about ten species of terrestrial herbs with nodding inflorescence. They are distributed in tropical Asia, Australia and the southwestern Pacific Islands in lowland and low montane forests. Plants are small to moderate size. Rhizome is subterranean, pseudobulbs globose, located just below or just above the ground. Sheaths are thin, discarded when mature. Leaves are terminal, large, elliptic, plicate, convolute, with petioles forming a pseudostem, and deciduous. Inflorescence arises from the side of leafy pseudobulb. Raceme is nodding and crowded with medium-sized, partially open flowers in white or pink. Lip is three-lobed, yellow. Herbs are annuals shedding their leaves and staying dormant during the dry season (Pearce and Cribb 2002).
