Annotations: endexine very thin; tristyle flowers; 3 types of anthers: (1) long filaments, blue pollen grains, size medium (2) long filaments, yellow pollen grains, size smaller than (1) (3) short filaments, yellow pollen grains, size small; more psilate ornamentation; no starch; apertures: 3 colpori and 3 pseudocolpi inbetween

Author(s) of diagnosis: Halbritter, H.; Weber, M.
