Primrose-Yellow Slipper Orchid is a very rare, small sized, hot to warm growing, multi-flowered terrestrial orchid. It carried distichous, oblong-lanceshaped, clear green leaves that are trifinely toothed at tip. The plant blooms on an erect, 10-30 cm long, green, velvet-hairy inflorescence that has several flowers that open in succession from the lowest one. The dorsal sepal is erect or hooded over; the lateral sepals form a synsepal. The petals grow horizontally or slightly downwards; the lip is pouch- or shoe-shaped with inrolled margins. The short column has two lateral fertile anthers, a fleshy apical staminode, and two pollinia. The stalked, convex, disc-like stigma is trigrooved and lies behind and below the staminode. Primrose-Yellow Slipper Orchid is endemic to northern Sumatra, found only in southern Aceh, at 1000 m.
