Identification. Gamogyne burbidgei is defined by con- nate pistils, a pistillate flower zone with a conspicuous zone of pistillodes at base, a spadix fertile to the tip, thecae not set in deep pits, parietal placentation, the spathe remaining tubular with an oblique terminal orifice dur- ing most of pistillate anthesis, and only inflating at sta- minate anthesis, by the spathe limb rostrum not reflexing at staminate anthesis and lacking rostral keels, and by roots producing with copious plantlets ( Low et al. 2018). Distribution and ecology. Common in Western Sabah, extending down to the Crocker Range until Brunei. Rheophytic among boulders in stream beds or on stream banks, below 100 m elev.
