Ewangoa, a new threatened Central African genus of Euphorbiaceae‐Acalyphoideae
TAXON, Volume 75, Issue 2, April 2026.Abstract A new morphologically divergent genus and species of Euphorbiaceae from the Democratic Republic of the Congo, Ewangoa cardiophora, is described and illustrated. This taxon is easily recognised by its leaf‐opposed inflorescences, which are surrounded by a single cordiform involucral bract. Molecular phylogenetic evidence shows that Ewangoa is a

FEBS Open Bio, Volume 16, Issue 3, Page 503-519, March 2026.Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Madagasikaria (Malpighiaceae): A New Genus from Madagascar with Implications for Floral Evolution in Malpighiaceae [PDF]
, 2002 Madagasikaria andersonii is described here as a new genus and species of Malpighiaceae from Madagascar. The phylogenetic placement of Madagasikaria was estimated by using combined data from ndhF and trnL-F chloroplast sequences and phytochrome (PHYC) and
