Description edit
Vegetative characteristics edit
Euryale is an annual or perennial, rhizomatous, aquatic herb with erect, unbranched rhizomes.[8] The adaxial leaf surface is green, and features prickles at the veins. The abaxial leaf surface is violet and displays prominent, prickly venation.[9]
Generative characteristics edit
The pedunculate, 5 cm wide flowers have prickly peduncles and sepals.[10] The stigma has 8-9 stigmatic rays. The prickly fruit bears black,[9] smooth, arillate,[8] globose, 6-10 mm wide seeds.[10]
Taxonomy edit
Publication edit
It was published by Richard Anthony Salisbury in 1805.[1]
Species edit
It has one extant species:[1]
- Euryale ferox Salisb.
And several fossil species:
- †Euryale yunnanensis Y. Huang & Z. Zhou[2]
- †Euryale nodulosa C. & E. M. Reid[3]
- †Euryale europaea C. A. Weber[4]
- †Euryale lissa Reid[5]
- †Euryale akashiensis Miki[6]
- †Euryale sukaczevii Dorof.[2]
- †Euryale tenuicostata Dorof.[2]
- †Euryale limburgensis C. & E. In. Reid.[7]
Cytology edit
The chromosome count of Euryale ferox is 2n = 58.[11]
Ecology edit
Habitat edit
Distribution edit
Euryale is found in the area that stretches from Northern India to the Russian Far East and extends into temperate East Asia.[1] Recently, it has also been recorded in Serbia, Europe. It was likely dispersed to Serbia through migrating birds.[13]
Conservation edit
The IUCN conservation status of Euryale ferox is least concern (LC).[12]
Fossil record edit
Euryale seeds and prickles are well preserved in the fossil record.[14] Today, Euryale only occurs in the region spanning from Northern India to the Russian Far East, and extends to temperate East Asia.[1] But in the Pliocene period it also occurred in central Europe.[15]
