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
[edit]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.
