Echinodorus berteroi
Encyclopedia
In Rataj's taxonomy E. berteroi is in Section Berteroii, Subgenus Echinodorus.
Several varieties are named in the literature, but their exact status in such a variable plant seems uncertain.

, Central America and the West Indies. It ranges through the tropical, sub-tropical and edges into the temperate zones of its range.
often modified into phyllodes, 10 - 45 cm long x 0.5 - 4 cm wide, linear to narrowly elliptical, of very variable shape and size, light-green, membraneously transparent, network between the veins often lighter or darker, thus the submersed leaves
often appearing mosaic-like coloured. Emerse leaves
long-petioled, 5 - 55 cm long, blades light-green, cordate, 5 - 12 cm long x 3 - 5 cm wide, in terrestrial dwarf forms the blades are ovate, truncate at the base, 2 - 5 cm long x 1 - 2 cm wide. In the blades there are very clear pellucid lines 1 - 5 mm (exceptionally up to 11 mm) long.
Stem upright, inflorescence
compound, branched in lower whorls. In terrestrial forms stem only 6 - 10 cm long. Corolla white, about 1.5 cm in diameter, stamens 12, achenes numerous in echinate head, nutlets grey-brown, 2.5 - 3.5 mm long x 1 - 1.3 mm wide, broadly keeled, with 2 winged ribs alternating with 3 non-winged ribs; facial gland single, close to the beak, indistinct or quite absent.
Mature specimens may have between 10 - 30 leaves

.
Can be divided, or in submerse plants, adventitious plantlets will form on the infloresence and can be divided and planted out.
Seed will be set in emerse plants, and can be planted out in shallow trays with sand and shallow warm water.
Prefers soft, rather acid water. Sub-tropical to tropical temperatures. It doesn't seem to thrive in hard water.
Will grow in and by the pond
in warmer regions, but must be protected from frost.

Distribution
Very large range, perhaps the most extensive of the genus, growing in shallow and periodic waters. It can be found even in almost dry places, growing dwarfed, almost like a form of E. tenellus.southern parts of the United States

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Strictly, it is the part of the shoot of seed plants where flowers are formed and which is accordingly modified...
