Flowers homostylous, 4-merous, pedicel 0.4–1.2 cm; calyx 0.5 × 0.5 cm, green, winged, not keeled, tubular, glabrous; corolla yellowish, infundibuliform, tube 2 cm, lobes 2 × 1 cm, at base obovate, at apex rounded; stamens 2 cm, isodynamous, adnate, conation 7 mm; ovary 7 × 3 mm, style ca. 1.5 cm, stigma bilobed. Fruit septifragal capsule.

Habitat and distribution:— Schultesia crenuliflora occurs in “campo rupestre” at altitudes above 900m, is considered in the list of rare species (Calió & Guimarães 2009), and is endemic to Bahia (Siqueira et al. 2014, Calió et al. 2015), being registered for the cities of Abaíra, Andaraí, Barra da Estiva, Ibicoara, Lençóis, Mucugê, Palmeiras, Piatã, Rio de Contas and Seabra (Siqueira et al. 2014). It is also considered vulnerable (VU) (IUCN 2020, CNCFlora 2014 b, Guimarães et al. 2014). The distribution modeling analysis recovered high suitability for the occurrence of the species in the entire northern portion of the ER, allowing to infer the occurrence of the specie also for the Serra Geral de Licínio de Almeida (Fig. 1, Fig. 2E, Fig. 3G, Fig. 4E, Appendix 1).

Comments:—It can be identified and differentiated from Schultesia bahiensis by the coriaceous leaves (vs. chartaceous leaves) and internodes generally larger or equal to the size of the leaf (almost always smaller than internodes throughout the entire plant), and the yellowish corolla (Siqueira et al. 2014). Like S. bahiensis, this species can vary in the amount of flowers, with up to 4 flowers being observed in each inflorescence and can be collected with fruits and flowers throughout the year (Siqueira et al. 2014).
