“…Nonetheless, their work also supports the circumscription of the new species in Mimosa ser. Stipellares due to the presence of vessels in large clusters, a feature apparently restricted to species of this series (Machado & Marchiori 2017). On the other hand, Mimosa baptistae may be easily confused as an armed version of Mimosa bifurca when flowers are absent.…”

A new glandular Mimosa species from Southern Brazil and insights about its glandular trichomes micromorphology

Mimosa baptistae is a new species presenting stalked glandular trichomes that give it a glutinous appearance, mainly with respect to the leaflets. Furthermore, it is an aculeate species, with multijugate leaves, white stamens, and fruits also covered by glandular trichomes. A herbaria survey and fieldwork only recorded this species as occurring on sandstone outcrops of the city Caçapava do Sul, Brazil. The species may be confused with other species of Mimosa sect. Batocaulon ser. Stipellares such as M. bifurca, M. sobralii and M. lepidota. However, features such as absence/presence of aculei, stamens color, habitat, and flower features are useful for distinguishing them from the new species. Here, we provide notes on morphology, geographic distribution, as well as anatomical detail of its glandular trichomes and content. Finally, we discussed the taxonomic significance of the micromorphology of glandular trichomes and their content in Mimosa ser. Stipellares as well as the potential applicability of such features to better understand the morphology of this series.

“…Nevertheless, we found some exsiccates of M. baptistae identified as M. intricata. For example, Machado & Marchiori (2017) showed some wood anatomical features for M. baptistae, which was mistakenly identified as M. intricata. Nonetheless, their work also supports the circumscription of the new species in Mimosa ser.…”
