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 : 452

35. Ipomoea squamosa Choisy, Prodr. 9: 376. 1845. Fig. 6n

Flowering & fruiting: Flowering in November; fruiting not seen.

Distribution: It is distributed throughout the Neotropics (Wood et a l., 2020). In Brazil, it is found in nearly all regions except the South. In the Northeast, it occurs only in Bahia, Maranhão ( Simão-Bianchini et al., 2024), and Paraíba (Lima & Melo, 2019). According to the Flora and Funga of Brazil, it is present in the Amazon, Cerrado, Atlantic Forest, and Pantanal domains. In Paraíba, however, we encountered this species growing in the Caatinga area, marking the first record of I. squamosa in this phytogeographic domain. It is considered a rare species in the IR of Cajazeiras.

Specimens examined: BRAZIL, Cajazeiras, Sítio Javigor, Fazenda o Paraíso , 01.11.2018, fl., V. M. Cotarelli 2897 ( RB digital image!) .

Notes: This species is recognized by its simple and entire leaves with a sagittate or oval leaf blade, entire or toothed margins, outer sepals half the size of the inner ones, with conspicuous scarious margins, corolla infundibuliform, glabrous, and pinkish, and stamens included.
