A new species of Ochna (Ochnaceae) from the Barberton Mountains of Mpumalanga, South Africa.
Ochna barbertonensis is described as a new species from the Barberton Mountains in Mpumalanga, South Africa. The new species is characterised by its suffrutescent habit, elongate-deltoid stipules sometimes with broadened base, mucronate leaf tip and high anther to filament ratio, where the anthers are ca. two times longer than the... -

Cladoceras rovumense sp. nov. (Gentianales-Rubiaceae), a new species from southeast Tanzania and northeast Mozambique.
Following a review of the circumscription of the genus Cladoceras Bremek. (Rubiaceae) in relation to Tarenna Gaertn., the new species Cladoceras rovumense I.Darbysh., J.E.Burrows & Q.Luke sp. nov. is described from the dry forests of the Rovuma Centre of Plant Endemism (CoE) in southeast Tanzania and northeast Mozambique. This species...Darbyshire, Iain ; Burrows, John E. ; Luke, Quentin ; Langa, Clayton

Phylogenetics of Ochna (Ochnaceae) and a new infrageneric classification.
Advances in high-throughput DNA sequencing are allowing faster and more affordable generation of molecular phylogenetic trees for many organisms. However, resolving relationships at species level is still challenging, particularly for taxonomically difficult groups. Until recently, the classification of Ochna had been based only on morphological data. Here, we present the...Shah, Toral ; Mashimba, Fandey H. ; Suleiman, Haji O. ; Mbailwa, Yahya S ; Schneider, Julio V …

Justicieae II: Resolved Placement of Many Genera and Recognition of a New Lineage Sister to Isoglossinae.
We present phylogenetic results for Justicieae, the largest of the major lineages of Acanthaceae. With 300% more sequence data and a similarly increased but also more geographically representative taxon sample compared to the only previous study of the lineage as a whole, we confirm the existence of the Pseuderanthemum Lineage,...McDade, Lucinda A. ; Kiel, Carrie A. ; Daniel, Thomas F. ; Darbyshire, Iain
