[2] Triglochin scilloides is an annual herb growing in or just next to water in several types of shallow aquatic habitat, including vernal pools, mudflats, and ditches.

The plant takes the form of a tuft of basal leaves around a very short stem.

The pistillate flower is composed of a threadlike style which may be up to 20 centimeters long tipped with a stigma which floats on the water surface.

[citation needed] The species was first described in 1804 by Jean Louis Marie Poiret (as Phalangium scilloides).

[2] In 2010, it was moved to Triglochin scilloides, the name accepted by Plants of the World Online as of March 2024[update].
