Helanthium bolivianum "quadricostatus"

The name "Echinodorus quadricostatus" is a trade name for various varieties of Helanthium bolivianum. In addition, it is also found under further denominations like Echinodorus magdalenensis (= E. quadricostatus var. magdalenensis), E. xinguensis (= E. quadricostatus var. xinguensis), E. bolivianus or "Echinodorus grisebachii" in the trade.
One of these forms only grows to under 5 cm in height when cultivated submersed, which makes it an ideal rapidly growing foreground ground cover. Another variety grows as vigorously, but to a height of over 20 cm.
