Caldesia is a genus of aquatic plants. It includes three living species widespread across Europe, Asia, Africa and Australia.[1][2][3] The genus "has an extensive Oligocene through Pleistocene fossil record in Eurasia,"[4] and has been found in fossil strata of the United States (Idaho and Vermont) as well. Ten fossil species have been described for the genus.
Taxonomy
The genus name of Caldesia is in honour of Ludovico (Luigi) Caldesi (1821 - 1884), an Italian politician and botanist.[5]
The genus was circumscribed by Filippo Parlatore in Fl. Ital. Vol.3 on page 598 in 1860.
Description

Carpels few or numerous in a single whorl, free, each with 1 ovule; styles subventral. Fruitlets drupaceous, with woody endocarp and spongy exocarp, swollen, with a short subventral beak, smooth or with tubercles or spines.
