Abstract

Subtribe Galipeinae (tribe Galipeeae) is the most diverse group of Rutaceae (the orange family) in the Neotropics, with 27 genera and ca. 130 species. The largest genus in the subtribe is Conchocarpus, with ca. 50 species, distributed from Central America to southern Brazil, and is particularly diverse in the Brazilian Atlantic Forest. The circumscription of the genus was recently changed to accommodate the species of Almeidea. However, even with this inclusion, Conchocarpus did not appear as monophyletic because the position of C. concinnus, which appeared in a clade with the other genera of Galipeinae rather than in the clade with the other species of Conchocarpus. The objective of the present study is to investigate the phylogenetic position of four other species of Conchocarpus (hereafter called ``C. gauchaudianus group{''}) that share morphological traits and geographical distribution with C. concinnus suggesting a close phylogenetic affinity. Phylogenetic analyses were based on morphological and molecular data from nuclear regions ITS-1 and ITS-2 as well as plastid regions trnL-trnF and rps-16, and were conducted with parsimony and Bayesian inference as optimization criteria. Results showed Conchocarpus as polyphyletic with its species divided in two clades, one, herein called ``the Conchocarpus sensu stricto group,{''} includes the type species C. macrophyllus, and the other ``the Conchocarpus gaudichaudianus group{''} includes C. concinnus. The latter group is here recognized as a new genus, Dryades, the name given by Carl Friederich von Martius (1794-1868) to the Domain of the Atlantic Forest in Brazil, inspired by the tree nymphs in Greek mythology. Floral structure and leaf morphology provided further support to the findings of phylogenetic analysis. A description of the new genus, new combinations, a key to the species of the new genus, discussions of the affinities of the species are also provided, as well as data on the conservation status of the species of Dryades. Additionally, new data on floral structure of C. heterophyllus, C. macrophyllus and C. minutiflorus (all from the Conchocarpus sensu stricto group) are provided. (AU)
