Flowering & fruiting: Flowering from April to September; fruiting not seen.

Distribution: It is distributed throughout South America, usually grows on disturbed roadsides at low altitudes. In Brazil, it is found in the Central-West, only in Mato Grosso; North in Acre and Amazonas; Southeast in Minas Gerais and Rio de Janeiro; South in Paraná, Rio Grande do Sul and Santa Catarina; and Northeast in Bahia ( Wood et al., 2020), Pernambuco ( Delgado-Júnior et al., 2023), Rio Grande do Norte ( Marinho et al., 2023), and in this study, we are expanding its distribution to the state of Paraíba, where it is occasional, with few records in the IRs of Cajazeiras, Campina Grande and Patos in areas of Caatinga.

Notes: This herbaceous vine is recognized by its simple leaves with entire or 2-toothed blades at the base, ciliate sepals, with the outer ones elliptical or oval-lanceolate and the inner ones oval and shorter (0.1–0.2 cm in length). The corolla is diminutive (1.5–2 cm long), infundibuliform to campanulate, pink or pale lilac with a purple tube, and has included stamens.

This species is often misidentified as I. triloba L. and is treated as a synonym in the Flora and Funga of Brazil ( Simão-Bianchini et al., 2024). However, the authors follow Wood et al. (2020) and consider it as distinct.
