Description:

Seeds of Limosella aquatica and Limosella acaulis, from herbarium specimens at New Mexico State University. Limosella acaulis in New Mexico has frequently been referred to Limosella pubiflora, but it is not clear whether or not these are distinct taxa. However, Limosella acaulis and Limosella aquatica clearly are distinct; differences in seed color & shape are shown here.
