Echinodorus cordifolius is a species of aquatic plants in the Alismatales. It is native to Mexico, the West Indies, Central America, South America (as far south as Paraguay) and the southeastern United States (Texas to Florida and as far north as Iowa).[1][2]
Found in marshes, swamps and ponds. Blooms in the late summer to early fall.
Herbs, perennial, stout, to 100 cm; rhizomes present. Leaves emersed, submersed leaves mostly absent; petiole 5–6-ridged, 17.5–45 cm; blade with translucent markings distinct lines, ovate to elliptic, 6.5–32 ´ 2.5–19.1 cm, base truncate to cordate. Inflorescences racemes, of 3–9 whorls, each 3–15-flowered, decumbent to arching, to 62 ´ 8–18 cm, often proliferating; peduncles terete, 35–56 cm; rachis triangular; bracts distinct, subulate, 10–21 mm, coarse, margins coarse; pedicels erect to ascending, 2.1–7.5 cm. Flowers to 25 mm wide; sepals spreading, 10–12-veined, veins papillate; petals not clawed; stamens 22; anthers versatile; pistils 200–250. Fruits oblanceolate, plump, 3–4-ribbed, abaxially 1-keeled, 2–3.5 ´ 0.9–1.5 mm; glands 3–4; beak terminal,1–1.3 mm. 2n = 22.
Echinodorus cordifolius is very easily recognized, as it is the only species with arching to decumbent inflorescences. In addition, it is the only one with papillate veins on the sepals.
Easily cultivated in neutral to soft water and tropical to sub-tropical temperatures. Rich substrate and good light. Common in the cultivated aquarium trade.

Plant for ID: Bangalore: Sept 2024: 1 correct image as above.
Please help ID this plant photographed at Bangalore International center. I understand that the white flowers belong to another plant. It would be helpful if you could help ID that plant as well. I could not get photos of the leaves of the white flower plant.


Thank you.


I was not able to match it with anything on the Araceae page.
Do you think it is Calla palustris?


It could be.


Leaves appear to be slightly different than those on net.


This one is really strange amalgamation of 2 aquatic species the leaves are that of Calla palustris (bog arum), I almost 100% sure given the leaf morphology and aquatic habit. The flower of this species is funnel like spathe, a constant of araceae family.
The flower attached is that of Sagittaria latifolia (Duck potato), but the arrow shaped leaves are no where to be seen. My guess is that the rhizome is buried under water  and is flowering. It could be Echinodorus also.
As for Echinodorus cordifolius the leaf morphology of this South American Amazon species light green with striated throughout. Leaf is unlikely to be that of any Echinodorus.


I agree that the leaves are of Calla palustris, and the white flowers are of Echinodorus cordifolius. Though I tried, I could not find any leaves of Echinodorus cordifolius.
Thank you very much for all the input. As always, very thankful for this group, and for the effort everybody put into correctly identifying plants.
