Recent advances in understanding Apiales and a revised classification
A unified picture of relationships has now emerged regarding the delimitation of Apiales, which includes the recognition of the new suborder Apiineae (comprising the four core families) and two new subfamilies within Apiaceae (Azorelloideae and Mackinlayoideae). Expand
A molecular phylogenetic study of southern African Apiaceae.
The southern African origin of subfamily Apioideae is corroborated, and the positions of the herbaceous Lichtensteinia and Annesorhiza clades within the subfamily suggest, surprisingly, that its ancestor was herbaceous, not woody. Expand
Chemical Composition, Leaf Trichome Types and Biological Activities of the Essential Oils of Four Related Salvia Species Indigenous to Southern Africa
The essential oils from fresh aerial parts of four Salvia species indigenous to southern Africa were obtained by hydrodistillation and analyzed by GC and GC/MS and exhibited antiplasmodial and anti-inflammatory activity and poor antioxidant activity against the DPPH radical at 100 μg/mL. Expand
Trichomes, essential oil composition and biological activities of Salvia albicaulis Benth. and S. dolomitica Codd, two species from the Cape region of South Africa
The toxicity profile of the two oils evaluated against the human kidney epithelium cells indicated some degree of toxicity in comparison to 5′-fluoro-uracil, and in vitro pharmacological properties of the essential oils were evaluated. Expand
Generic relationships in Araliaceae: looking into the crystal ball
This work reviews the status of the 41 genera currently recognised in Araliaceae and considers alternative circumscriptions for those that are not monophyletic, and suggests that Polyscias sensu lato will likely be realigned into 5–8 geographically coherent genera, while Schefflera sensu Lato will be split into 10–16 genera.

The taxonomic value of fruit structure in the subfamily Saniculoideae and related African genera (Apiaceae)
A cladistic analysis based on all anatomical characters shows that Lichtensteinia, Polemanniopsis and Steganotaenia are directly basal to the Saniculoideae, and that there is sufficient morphological evidence to expand the circumscription of the subfamily to include these genera. Expand
Circumscription of Apiaceae tribe Oenantheae
Representatives of eight genera native to North America comprise a monophyletic group, and results from relative rate tests suggest that this lineage is evolving much faster than any other major clade recognised within the tribe. Expand
The generic concept of Lebeckia (Crotalarieae, Fabaceae): Reinstatement of the genus Calobota and the new genus Wiborgiella
Abstract Evidence from the internal transcribed spacer (ITS) of nuclear ribosomal DNA and plastid rbcL data revealed that the genus Lebeckia Thunb. as currently circumscribed may not be monophyletic.Expand
Phylogenetic position of African and Malagasy Pimpinella species and related genera (Apiaceae, Pimpinelleae)
The phylogenetic position of the African and Malagasy species of Pimpinella is assessed using nrDNA ITS sequence data and a representative sampling of the genus, including 16 species from Africa andExpand
The taxonomic affinity of Carum piovanii Chiov. and some Bunium species (Apiaceae)
The phylogenetic analyses place C. piovanii within the African peucedanoid genus, Afroligusticum and not with its congeners, and the new combination Afroligsusticum p Giovanii is proposed. Expand
