Utricularia papilliscapa is a bladderwort endemic to the Kimberley region of Western Australia. It is named for the papillose penduncle base.

Utricularia papilliscapa is a small bladderwort that grows around 5-14 cm in height and flowers around 1.5cm wide. The lower corolla lip is divided into three broad lobes. The upper corolla lip is small and upright, with a deep ‘V’ shaped notch. The corolla spur is long and pointed, facing backwards relative to the corolla lobes. The flowers are pale purple in colour, with a yellow palate and dark purple streaks near the center of the bloom. The lower parts of the peduncle and papillose.

The species is known from the northern Kimberley region where it is associated with sandstone. I encountered it north of Kalumburu where it is locally abundant towards the end of the wet season. The species usually grows in grassy, open herbfields and prefers deeper accumulations of soil in waterlogged areas (as opposed to skeletal substrates over rock).

Utricularia papilliscapa is somewhat similar to the sympatric U. cowiei and shares a similar lower corolla lip shape but is distinguished by its deeply notched upper corolla lip (the upper corolla lip of U. cowiei is entire). It has a superficial resemblance to U. tridactyla but differs in that its lower corolla lip lobes are broad and moderately divided (the lobes of U. tridactyla are narrow and deeply divided).
