TL;DR: Analysis of rbcL sequence data indicates a close and strongly supported relationship to Ochnaceae and Quiinaceae, but does not resolve the relationships between these taxa.
Abstract: Medusagyne oppositifolia Baker is the sole member of Medusagynaceae Engl. & Gilg and its phylogenetic position has been unclear. Analysis of rbcL sequence data indicates a close and strongly supported relationship to Ochnaceae and Quiinaceae, but does not resolve the relationships between these taxa. Together the three families form a monophyletic group with a somewhat more distant relationship to other linalean groups including Malpighiaceae, Linaceae and phyllanthoid Euphorbiaceae.

TL;DR: Bayesian ancestral state reconstructions showed that zygomorphic flowers with adaptations to buzz-pollination, a syncarpous gynoecium evolved independently in Quiinoideae and Ochninae, numerous ovules, septicidal capsules, and winged seeds with endosperm are the ancestral condition in Ochnoideae.
44 citations
TL;DR: The most strongly supported subclade of two of the three families in molecular analyses, Quiinaceae and Medusagynaceae, is also particularly well supported by floral structural features, including the presence of functionally and morphologically unisexual flowers.

TL;DR: From the leaves and stem bark of Campylospermum flavum (Ochnaceae), three compounds, namely 4‴-O-methylagathisflavone, flavumchalcone, and flavumindole have been isolated together with 10 known compounds, including three flavonoids, two biflavonoid, two alkaloids,Two nitrile glucosides, and glucopyranosyl-β-sistosterol.

TL;DR: Five of Van Tieghem’s Ochna segregates are present in Madagascar: Diporidium Tiegh, Discladium Tiegh.
Abstract: The pantropical genus Ochna L. (Ochnaceae) comprises c. 80 species of trees and shrubs from Africa and Asia (VERDCOURT, 2005). In the early 20th Century, VAN TIEGHEM (1902a, 1902b, 1902c, 1903, 1907) worked on a global taxonomic revision of the family Ochnaceae in which he split the family into a total of 57 genera, describing 46 as new. VAN TIEGHEM (1902b) split the genus Ochna into 15 segregate genera based on the dehiscence of the stamens (longitudinal or poricidal), the morphology of the embryo (isoor heterocotyledonous), and number of carpels. Five of Van Tieghem’s Ochna segregates are present in Madagascar: Diporidium Tiegh., Discladium Tiegh., Ochnella Tiegh., Pleuroridgea Tiegh. and Polythecium Tiegh., while he considered Ochna sensu stricto to be absent. Van Tieghem also employed very narrow species concepts and described many new species in the family.
