“…This often makes their correct identification difficult. Taxonomic boundaries within Ceiba sometimes become tenuous, even more so if we consider that the species of the complex are inter-fertile and can produce fertile hybrids, which opens up an almost infinite range of individual morphological characteristics, especially in floral structures (Gibbs & Semir 2003;De Egea et al 2012;Lozano & Zapater 2018;Pezzini et al 2021). In addition, some key characters for identification are often lost during the process of botanical material preparation or specimens are incomplete (Gibbs & Semir 2003).…”

Based on the review of herbarium specimens, geo-referenced live images, and field observations, a new species of the genus Ceiba (Malvaceae) is described. Ceiba camba, the new species, has previously been confused with other species in the Ceiba insignis complex, specially with C. speciosa, and went undifferentiated despite having a wide distribution in the lowlands of central-western South America and being quite common. However, the new species here described shows clear visible morphological differences from C. speciosa and the other members of the genus. The main similarities and differences with other morphologically and geographically close species of the C. insignis complex (C. chodatii, C. crispiflora, C. insignis, C. lupuna, C. pubiflora, C. speciosa) are discussed.
