Tritoniopsis parviflora green anthers

The green floral bits like bars of soap are the anthers positioned at the Tritoniopsis parviflora filament tips, three per flower. The angles of a couple of dorsal tepals under which the anthers are usually hidden allow the ones in picture to be seen.

The pair of upper lateral tepals are opening wide and curving back. The lower three tepals completing the corolla bear the maroon markings giving the flowers their second colour (Manning, 2007; iNaturalist).
