Taxonomy edit

Type specimen edit

The type specimen was collected by C.T. Lima and L. Lima in the Curuá Una River in the Prainha municipality in the state of Pará, Brazil on the 17th of July 2011. This species is only known from the type locality.[3]

Placement within Nymphaea edit

It is placed in Nymphaea subgenus Hydrocallis.[3]

Etymology edit

The specific epithet rapinii honours Prof. Dr. Alessandro Rapini 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] It inhabits the Curuá Una River, where seasonal changes of water levels occur based on precipitation, yet the river never dries up completely. Nymphaea rapinii was found growing in depths of 3 meters, where it occurred sympatrically with Nymphaea lingulata and Nymphaea paganuccii.[3]
