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.

Nomenclatural notes on some European elm names (Ulmaceae)

open access: yesTAXON, EarlyView.
Abstract The typification of the elm names Ulmus laevis, U. minor, and U. pumila is discussed. Ulmus laevis is lectotypified on a Pallas illustration published in his Flora Rossica. No original material could be located for U. minor and a neotype is designated (a specimen at SLBI). Ulmus pumila is lectotypified on a specimen in LINN.
