“…Rutaceae is a large family (c. 154 genera and 2100 species) with great diversity in morphological characters and a nearly worldwide distribution (Appelhans et al, 2021 ; Groppo et al, 2022 ; Kubitzki et al, 2011 ; Zhang et al, 2008 ). This family comprises tall or short trees, shrubs or climbers, and rarely herbs.…”

Rutaceae is a large family, and the genus‐level classification in the subfamilies or tribes of this family is not unified based on different taxonomic treatments. Until now, phylogenetic relationships of some genera in traditional tribe Ruteae have not been clearly resolved. In this study, seven new complete plastomes of this tribe were sequenced, and a comparative analysis was performed to investigate their plastome characteristics and evolution. In addition, we inferred the phylogenetic relationships of Ruteae based on complete plastome and nuclear ITS data. All plastomes exhibited a typical quadripartite structure and were relatively conserved in their structure and gene arrangement. Their genome sizes ranged from 154,656 bp to 160,677 bp, and the size variation was found to be associated with differences in IR expansion and gene loss. A total of 112 to 114 genes were identified in the genomes, including 78 to 79 protein‐coding genes, 30 tRNA genes, 4 rRNA genes, and 2 pseudogenes. Sequence divergence analysis indicated that non‐coding regions exhibited a higher percentage of variable characters, and nine non‐coding and six coding regions were identified as divergent hotspots. Phylogenetic results based on different datasets showed that this tribe was divided into three reciprocally exclusive groups. The phylogenetic analyses between plastome and nuclear ITS data were partly incongruent with each other. This study provides new insights into plastome evolution of Ruteae as well as Rutaceae. The availability of these plastomes provides useful genomic resources for molecular DNA barcodes and phylogenetically informative markers and deepens our understanding of the phylogeny in Ruteae.

“…The most diverse group of Rutaceae in the Neotropics is the tribe Galipeeae (Cusparinae sensu Engler 1931), belonging to the Zanthoxyloideae, with two subtribes, Pilocarpinae and Galipeinae. The species of Galipeinae have particular morphological characteristics such as predominantly zygomorphic flowers with more or less tubular corolla and a reduced number of fertile stamens (Engler 1931, Kallunki and Pirani 1998; Groppo et al 2008; Bruniera et al 2015) and are distributed from southern Mexico to Bolivia and southern Brazil, but are found mainly in the Atlantic Forest Brazilian region, with about 100 species (Groppo et al 2022; Pirani and Groppo 2022).…”

Rutaceae (Sapindales) is represented by approximately 2040 species and 150-170 genera. Conchocarpus is the genus with the highest number of species and is circumscribed by a combination of character states, making it a polymorphic group. A recent study proposed a new genus, Dryades, formed by species formerly positioned in Conchocarpus. This study aims to describe the pollen morphology of Dryades species, comparing it with the palynology of phylogenetically related species, to present data that can characterize the species of Dryades. We analyzed the pollen grains of Dryades species and eight species of the genera Andreadoxa, Angostura, Erythrochiton, Galipea, Rauia and Conchocarpus. The pollen grains were acetolyzed, measured, described qualitatively, and analyzed quantitatively. Illustrations using light microscopy (LM) and scanning electron microscopy (SEM) are presented. Multivariate analysis was performed. The pollen grains are monads, isopolar, medium to very large in size, with subcircular to subtriangular amb, and oblate-spheroidal to prolate shape. The apertures are 3-or 5-colporate, varying in size (very small to very large colpi). The endoapertures are usually lalongate, rarely circular. The pollen grains analyzed are microreticulate, reticulate, macroreticulate, reticulate-baculate, baculate or verrucate-baculate. Both qualitative and quantitative characteristics of pollen grains proved to be important in distinguishing genera and grouping species within genera (in particular, the number of apertures, the length of the ectoaperture, the exine ornamentation and the size of the pollen grains). Dryades species show similarities in pollen morphology to species of related genera such as Andreodoxa, Galipea and especially Rauia. The shape of pollen grains and the number of apertures in Dryades are distinct from those found in Conchocarpus macrophyllus. The pollen data observed in this study confirm the pollen diversity of Rutaceae.
