The genus Ocimum L. (Lamiaceae) is composed of aromatic plants known for their peculiar strong smell added to their close similarities in morphological attributes, increase attention and applications as ethnobotanicals of culinary and medicinal use. There are reports of difficulty in Ocimum taxonomy. Seedling morphology and molecular characterization of some Ocimum accessions collected from Southwest states of Nigeria were carried out to delimit members of the genus. Morphological measurements were carried out on the seedlings characters and recorded. Molecular characterization was carried out on their fresh leaf‐samples. Statistical analyses of quantitative seedling data were performed using SAS/PC1 version 9.01. Seedling morphology reveals phanerocotylar epigeal with foliaceous cotyledon type; reniform and flabellate cotyledon shape, obcordate and obtuse cotyledon apex, cordate and truncate cotyledon base. There is a significant mean difference in all the quantitative seedling characters at p<0.05. Blast query reveals the accessions as five species exhibiting 99 % homologous identities with previous submissions in the GenBank database.
