Nymphaea caatingae is a species of waterlily endemic to Northeast Brazil. [1]
Nymphaea caatingae is an aquatic herb. [2] It has stoloniferous, subglobose tubers. The floating leaves are attached to the stem by glabrous, non-brittle, 2.3-8 mm wide,green to reddish petioles, which have two primary central air canals, as well as six smaller secondary ones. [3] The leaf blade is ovate, suborbicular to orbicular in shape and has flat and entire margins. [2] The apex of the leathery lamina is obtuse. [3]
Flowering occurs throughout the year. [3] The nocturnal flowers float on the water surface. [2] They have non-brittle, glabrous, brownish peduncles with six central primary air canals and twelve smaller secondary, peripheral ones. [3] There is an abrupt transition from the white petals to stamens and staminodia are absent. [2] The ellipsoid, ruminate, pilose seeds have trichomes arranged in interrupted, longitudinal lines. [2]
Proliferating pseudanthia are present, [2] which enable rapid vegetative reproduction under volatile environmental conditions. [4] Stolons are produced as well, but the proliferating pseudanthia are the main mode of vegetative propagation. [3]
The nocturnal, protogynous flowers last for two days. Autogamy does not occur. Fruit set has only been observed after cross pollination. [3]
It was first described by C.T.Lima and Ana Maria Giulietti in 2021. [1]
The type specimen was collected by C.T. Lima on the 13th of December 2009 in the municipality Itaberaba on the road to Ipirá in the state of Bahia, Brazil. [3]
It is placed in Nymphaea subg. Hydrocallis. It is morphologically closest to Nymphaea vanildae . [3]
In the Caatinga, it grows in temporary ponds, and in stagnant water. [3] It is endemic to Brazil and occurs in the Caatinga, as well as the Atlantic rainforest. [2]
Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, nymphaia and the Latin nymphaea, which means "water lily" and were inspired by the nymphs of Greek and Latin mythology.
