Capanemia, an orchid comprising seven species and mostly found in the Brazilian Atlantic rain forest, is divided into two sections based on leaf shape. Buzatto et al. examine floral morphology and anatomy and conclude that this current sectional division is not supported as, with the sole exception of Capanemia therezae, all species share a distinctive set of floral characters. A complete revision of the genus based on phylogenetic studies is thus required.
Ophiocaryon is a lesser-known genus in Sabiaceae, hitherto without detailed floral study and with unknown pollination mechanisms. Thaowetsuwan et al. examined floral morphology and anatomy revealing several unusual...
A survey of flowers of 16 species of Lockhartia determines that all have elaiophores (oil glands) of the trichomal type.
Recent molecular approaches have resulted in the re-circumscription of Gomesa and Oncidium (Orchidaceae; Oncidiinae), together with their respective clades. Stpiczyńska et al. compare the anatomical organization of the...
