Ipomoea violacea

A. P. S, Lima, M. T. A., Buril & Melo, J. I. M. de, 2024, Synopsis of Ipomoea (Convolvulaceae) in the state of Paraíba, Brazilian Northeastern, Rheedea 34 (5), pp. 430-456 : 453

39. Ipomoea violacea L., Sp. Pl., 161. 1753. Fig. 6s Flowering & fruiting: Flowering in August; fruiting not seen.

Distribution: Pantropical in distribution, this species is typically found on or near the sea or growing in mangroves. In the Americas, despite its wide distribution, it is not commonly abundant, being more frequent in the Caribbean and almost absent from the Pacific coast ( Wood et al., 2020). In Brazil, it is recorded only in coastal areas, with occurrences in Amapá (North region), Bahia, Paraíba, Pernambuco, including Fernando de Noronha Island, and Espírito Santo (Southeast). These gaps may be attributed to the lack of collections from beaches and mangrove ecosystems along the Brazilian coastline ( Alencar et al., 2021; Delgado-Júnior et al., 2024). In Paraíba, it is rare, with only one recorded population on Tambaba Beach in the IR of João Pessoa.

Specimens examined: BRAZIL, Conde, Tambaba , 23.08.2011, L. A . Pereira et al. 299 ( JPB!) .

Notes: It is commonly known as the “beach moon flower” and can be confused with I. alba in the field. A comparison has already been presented under this species.
