38. Ipomoea vespertilia F.D. Santos, G.C. Delgado-Júnior & Buril, Brittonia 71: 191. 2019. Fig. 5n

Flowering & fruiting: Flowering and fruiting from June to December.

Distribution: Endemic to the Caatinga in Northeast Brazil, it occurs only in the states of Ceará and Paraíba ( Santos et al., 2019; Wood et al., 2020; Simão-Bianchini et al., 2024). We found it in three municipalities in Campina Grande and Cajazeiras RI , being considered a rare species, but possibly its distribution is underestimated, given the difficulty of differentiating it from I. marcellia in dried material.

Specimens examined: BRAZIL, Cachoeira dos Índios, Serra do Quati , 6º54’48”S, 38º42’6”W, 03.06.2017, fl. & fr., F . C . Pinheiro 795 ( HACAM!) ;
