In Rataj's taxonomy E. longiscapus is in Section Cordifolii, Subgenus Echinodorus
long-petioled, petioles 1.5 - 3 x longer than the blades. Blades oval, ovate or cordate, at the tip obtuse or shortly acuminate, at the base lobate or abrupt, 9 - 11 cm long x 7 - 8 cm wide, in the terrestrial forms often only 3 cm long x 2 cm wide. Submersed blades oval or ovate, often nearly rounded. Blades trimmed with pellucid lines to 2 mm long.
Stem erect, longer than the leaves
, glabrous or rarely scabrous, 30 - 80 cm long. Inflorescence
racemose having 3 - 9 whorls containing 6 - 12 flowers each, proliferous. Bracts as long as the pedicels, or hardly longer, to 1.5 cm long, having 9 - 11 ribs and membraneous margins. Pedicels usually 1 - (2.5) cm long, sepals 5 - 6 mm long having 16 - 20 undistinct ribs, petals white, 1.7 - 2 cm long, corolla 2.5 - 4 cm in diameter. Stamens 20 - 25, anthers as long as the filaments, pistils numerous.
Aggregate fruit
globular or ovate, 5 - 7 mm in diameter. Achenes 2 - 2.3 mm long x 0.9 - 1 mm wide having usually 4 lateral ribs and (1) - 3 glands placed in a row in the upper half of the body. Beak erect or bent, 0.5 mm long.
Easy to cultivate and seems to withstand a wide range of water conditions and temperatures.
