Finding
SITF confirms this plant as Scaphosepalum swertiifolium (Oct 2024). S. swertiifolium and S. ursinum are the only species in the section with large sepaline pads and long caudae; however the rest of this flower doesn't fit the S. ursinum form. Illustrations and photos of S. swertiifolium and S. ursinum can be found in the IOSPE. These photos support S. swertiifolium over S. ursinum.
