Baldellia is a genus of aquatic plants commonly known as lesser water-plantains. It includes three species found across much of Europe and the Mediterranean from Ireland and the Canary Islands to Turkey and Estonia.[1][2] The genus is named in honor of the Italian nobleman Bartolomea Bartoloni-Baldelli.[3] Baldellia is very closely related to Echinodorus.


Leaves aerial, elliptical to lanceolate or linear-lanceolate. Flowers hermaphrodite, in 1 - 3 whorls in umbels or racemes, or long-pedunculate in leaf-axils. Stamens 6. Carpels numerous, spirally arranged in a globose head, free, each with 1 ovule; styles apical. Fruitlets achenial, longitudinally 5-ribbed (3 dorsal ribs and 2 closely approximated ventral ribs), with a short, apical beak. 2n=16.

Variable in form according to ecological conditions.
