Nymphaea caatingae is a species of waterlily that is endemic to north-eastern Brazil.[1]
Description
[edit]Vegetative characteristics
[edit]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]
Generative characteristics
[edit]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]
Reproduction
[edit]Vegetative reproduction
[edit]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]
Generative reproduction
[edit]The nocturnal, protogynous flowers last for two days. Autogamy does not occur. Fruit set has only been observed after cross pollination.[3]
Taxonomy
[edit]It was first described by C.T.Lima and Ana Maria Giulietti in 2021.[1]
Type specimen
[edit]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]
Placement within Nymphaea
[edit]It is placed in Nymphaea subg. Hydrocallis. It is morphologically closest to Nymphaea vanildae.[3]
