On the perils of mycorrhizal status lists: the case of Buddleja davidii.
One observation in a mycorrhizal check-list that Buddleja davidii is nonmycorrhizal has been perpetuated in subsequent citations and used in a number of analyses of mycorrhizal ecology and evolution. Direct observation of B. davidii from New Zealand and the UK shows extensive arbuscular mycorrhizal fungal structures inside B. davidii roots. The suggestion that B. davidii is nonmycorrhizal is therefore not supported. The use of mycorrhizal checklists for analysis of plant traits and evolution needs to be undertaken with care to ensure the validity of underlying data.
