36. Ipomoea tenera Meisner, Fl. Bras. 7: 289. 1869. Fig. 6o–p

Flowering & fruiting: Flowering and fruiting in June.

Distribution: Endemic to the Caatinga domain, with records in the Northeast, in the States of Bahia, Ceará, Paraíba, Pernambuco, and Rio Grande do Norte, and Southeast, in Minas Gerais ( Simão-Bianchini et al., 2024; Wood et al., 2020). In the state of Paraíba, we did not find any recent material, just a collection dating back almost 90 years, in a municipality in the IR of Cajazeiras and we believe that it is possibly extinct in the state.

Specimens examined: BRAZIL, Sousa, na pastagem, 21.06.1935, fl. & fr., B . Pickel 3894 ( IPA!) .

Notes: It was compared morphologically to I. heptaphylla under the comments of that species.
