Phylogeny and new sectional classification for the Cape Clade of the genus Indigofera (Fabaceae: Indigofereae)

open access: yesTAXON, EarlyView.
Abstract The genus Indigofera in the Greater Cape Floristic Region (GCFR) comprises a diverse assortment of species. Almost 90% of the region's Indigofera species belong to the Cape Clade, while the remaining species are scattered among the other three globally distributed Indigofera clades.

Taxonomy and dated molecular phylogeny of Allium oreophilum sensu lato (A. subg. Porphyroprason) uncover a surprising number of cryptic taxa

open access: yesTAXON, EarlyView.
Abstract Allium oreophilum, hitherto the representative of the monotypic A. subg. Porphyroprason from the second evolutionary lineage of Allium, is studied in detail. Over about 150 years, A. oreophilum was regarded as a somewhat polymorphous species with two synonyms, all described in the 19th century.

Resolving taxa in a challenging orchid species complex using evidence from phylogenetics, morphometrics and floral scent chemistry

open access: yesTAXON, EarlyView.
Abstract Species can be difficult to circumscribe using morphology alone, and additional data can thus be useful for resolving challenging species complexes. Here we provide a case study of a South African orchid species complex which we resolved by analysing morphology, floral scent chemistry and molecular data.
