Synonyms:Alisma grandiflorum Cham. & Schltdl., Echinodorus sellowianus Buchenau, Echinodorus argentinensis Rataj, Echinodorus grandiflorus var. longibracteatus Rataj, Echinodorus longiscapus Arechav., Echinodorus grandiflorus var. ovatus Micheli
Description:Subspecies Description - Leaves with pellucid markings present as lines, or rarely absent.

Discussion:Sold under the German commercial name "Grossbluemiger Igelschlauch" ("Large-flowered Hedgehog," transl.). Propagation may be by either adventitious plantlets of the inflorescences, by division of rhizomes, and by seeds. Best suited for paludariums and terrariums, as the plant does not thrive under water. It withstands a great fluctuation in temperature (De Wit, 1971; Mühlberg, 1980).

Micheli (1881) listed 11 collections in the protologue. We have examined at least four of them Bade 82, Tweedie s.n., Courbon s.n. and St. Hilaire 1816-21 C2. We believe all four to represent the same taxon. Consequently, there will be no difference in usage regardless of which one is chosen as the lectotype. We have chosen to designate Bâcle 82 since there are multiple specimens of the collection.
