Nymphaea paganuccii is a species of waterlily endemic to Brazil.[1][2]
Description[edit]
Vegetative characteristics[edit]
Nymphaea paganuccii is an aquatic herb.[2] It has cylindrical tubers, which are not stoloniferous. The glabrous, green, non-brittle petioles have four primary central and four secondary peripheral air canals.[3] The elliptic, suborbicular to orbicular leaf blade has a flat and entire margin.[2] The blade is 15.3–19.8 cm long and 10–17.3 cm wide.[3]
Generative characteristics[edit]
The nocturnal flowers float on the water surface.[2] The non-brittle, brownish, glabrous peduncle has six primary central and 12 secondary peripheral air canals.[3] The ovoid, smooth, pilose seeds have trichomes arranged in continuous longitudinal lines.[2] The seeds are 1–1.2 mm long and 0.7–0.8 mm wide.[3]
Reproduction[edit]
Vegetative reproduction[edit]
Both stolons and proliferating pseudanthia are absent.[3][2]
Generative reproduction[edit]
Flowering and fruiting has been observed in the month of July. Sexual reproduction plays a significant role in this species.[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 and L. Lima at depths of 1-3 m in a lagoon by the Tapajós river of the Santarém municipality in the state Pará, Brazil on the 18th of July 2011.[3]
Placement within Nymphaea[edit]
It is placed in Nymphaea subgenus Hydrocallis.[3]
Etymology[edit]
The specific epithet paganuccii honours Prof. Dr. Luciano Paganucci de Queiroz of the State University of Feira de Santana, Brazil.[3]
Ecology[edit]
Habitat[edit]
It occurs in the aquatic habitats of the Amazon rainforest.[2] The depth of the lagoon habitat in the type locality fluctuates based on precipitation in the region, with a complete dry period occurring between August and December. It occurs sympatrically with several other Nymphaea species, namely Nymphaea amazonum, Nymphaea pedersenii, Nymphaea rapinii, and Nymphaea lingulata. [3]
Pollination[edit]
