33. Ipomoea sericosepala J.R.I.Wood & R.W. Scotland, Kew Bull 70: 21. 2015. Fig. 5k–l

Flowering & fruiting: Flowering from April to September; fruiting from May to September.

Distribution: It occurs in Brazil and Bolivia ( Wood et al., 2020) where it is widely distributed, with records in all regions, in the Amazon, Caatinga, Cerrado, and Atlantic Forest domains ( Simão-Bianchini et al., 2024). In the study area, it is common, distributed across the IRs of Campina Grande, João Pessoa, and Patos , especially in more preserved Caatinga areas.

Notes:Until recently, this species was circumscribed into the genus Turbina Raf. , as Turbina cordata (Choisy) D.F.Austin & Staples. However , based on molecular studies, Wood et al. (2015) combined it in the genus Ipomoea . Some herbarium specimens were misidentified as I. brasiliana var. subincana ), sharing characteristics such as tomentose branches, petioles, and peduncles, a leaf blade with a cordate base, oblong sepals, and a pink infundibuliform corolla with included stamens. However, I. sericosepala differs by its cordiform to suborbicular leaf blade, densely sericeous-cinereous below, densely sericeous sepals, and oblong, tomentose, indehiscent capsules (vs. oval leaf blade, densely tomentose below, pubescent sepals, and dehiscent, globose, glabrous capsules).
