“…The Galipeinae were represented by all five currently recognized species of Almeidea [20, 21, 23], seven of Conchocarpus , and one each of Erythrochiton , Galipea , Neoraputia , Rauia , and Ravenia (the list of all species names and authors are listed in S1 and S2 Text). Given the wide geographic range of Almeidea rubra , individuals from three populations (two from Espírito Santo and Minas Gerais states, both in Brazil, and one from Bolivia) were included.…”

Subtribe Galipeinae (tribe Galipeeae, subfamily Rutoideae) is the most diverse group of Neotropical Rutaceae, with 28 genera and approximately 130 species. One of its genera is Almeidea, whose species are morphologically similar to those of the genus Conchocarpus. Species of Almeidea occur in the Atlantic Rain Forest of Eastern Brazil, with one species (Almeidea rubra) also present in Bolivia. The objective of this study was to perform a phylogenetic analysis of Almeidea, using a broader sampling of Galipeinae and other Neotropical Rutaceae, the first such study focused on this subtribe. To achieve this objective, morphological data and molecular data from the nuclear markers ITS-1 and ITS-2 and the plastid markers trnL-trnF and rps16 were obtained. Representatives of eight genera of Galipeinae and three genera of Pilocarpinae (included also in Galipeeae) and Hortia (closely related to Galipeeae) were used. Five species of Almeidea and seven of Conchocarpus were included, given the morphological proximity between these two genera. Individual (for each molecular marker) and combined phylogenetic analyses were made, using parsimony and Bayesian inference as optimization criteria. Results showed Galipeinae as monophyletic, with the species of Almeidea also monophyletic (supported by the presence of pantocolporate pollen) and nested in a clade with a group of species of Conchocarpus, a non-monophyletic group. Additionally, C. concinnus appeared in a group with Andreadoxa, Erythrochiton, and Neoraputia, other members of Galipeinae. As a result, Conchocarpus would be monophyletic only with the exclusion of a group of species related to C. concinnus and with the inclusion of all species of Almeidea with the group of species of Conchocarpus that includes its type species, C. macrophyllus. Thus, species of Almeidea are transferred to Conchocarpus, and the new combinations are made here.

Leaf anatomy and histochemistry of secretory structures of Zanthoxylum caribaeum Lam. (Rutaceae)

Rutaceae species, especially of the genus Zanthoxylum L., are known for possessing a well-diversified chemical composition with high potential for pharmacological activity. A variety of Zanthoxylum species are distributed throughout Brazil. This study aimed to characterize the leaf anatomy and identify the histochemical composition of the secretory material from the secretory structures of Z. caribaeum leaves. Leaves of Z. caribaeum were collected and processed for anatomical, histochemical and micromorphological characterization following standard methodologies. The leaves have an unstratified epidermis and glandular trichomes in epidermal depressions on the abaxial surface. Extrafloral nectaries were also observed on the abaxial surface. The leaf is hypostomatic and the stomata are anomocytic. The mesophyll is dorsiventral and has secretory cavities. The mesophyll cavities produce a secretion of lipidic nature and the cavities on the leaf margin produce a secretion of mixed nature, with neutral lipids and essences. In summary, our findings show that the leaves of Z. caribaeum have secretory structures like glandular trichomes that can function as extrafloral nectaries and cavities. The characterization of the leaf anatomy of Z. caribaeum can provide relevant data for future taxonomic studies of the genus.
