Additional Information at NatureServe

Diagnostic Characteristics:
The flowering scapes (stems) are reclining and rooting at the nodes, and these may be up to 60 cm long. Leaves are ovate to cordate (rarely lanceolate when plants are small). The flowers have petals 5-12 mm long with 12-25 stamens, and there are numerous ovaries (more than 20 at least). Echinodorus can be distinguished from Alisma because the inflorescence is generally not branched but has a whorl of pedicels) and the flower receptacle is conic with ovaries arranged spirally (rather than a ring).

Changes in moisture/hydrologic conditions of the habitat for this species would likely be detrimental. Changes could result from overstory removal, stream/wetland alteration or impacts due to erosion or soil deposition.
