Euryale tenuicostata is a fossil species of Euryale from the Miocene of Omsk, Russia. [1]
The ovoid to oval, 4.3–7.6 mm long, and 2.9–7.1 mm wide seeds have a slightly wrinkled testa. [2]
It was first published as Euryale tenuicostataP.I. Dorof. by Pavel Ivanovich Dorofeev in 1959. [1] It has been proposed to place it in a separate genus IrtysheniaP.I. Dorof. as Irtyshenia tenuicostata(P.I. Dorof.) P.I. Dorof. published by Pavel Ivanovich Dorofeev in 1972. [3] [4] Later it was proposed to place it in the genus PseudoeuryaleP.I. Dorof. as Pseudoeuryale tenuicostata(P.I. Dorof.) Doweld published by Alexander Borisovitch Doweld in 2022. [5] [6]
Fossils of E. tenuicostata occur in what is now Russia. [1]
The Nymphaeales are an order of flowering plants, consisting of three families of aquatic plants, the Hydatellaceae, the Cabombaceae, and the Nymphaeaceae. It is one of the three orders of basal angiosperms, an early-diverging grade of flowering plants. At least 10 morphological characters unite the Nymphaeales. One of the traits is the absence of a vascular cambium, which is required to produce both xylem (wood) and phloem, which therefore are missing. Molecular synapomorphies are also known.
