A corrected lectotypification of the name Artemisia umbrosa (= A. vulgaris var. umbrosa, Asteraceae) is discussed. It is demonstrated that Besser (1832) in fact cited in the protologue four concrete specimens that should ...

General recommendations regarding proper type designation of names of taxa described by Turczaninow in his Animadversiones series of articles (as well as in some other publications) are provided. It is concluded that, as ...

The genera Anemonastrum and Knowltonia earlier usually included in Anemone sensu lato (Ranunculaceae: Anemoneae) were recently proposed to be recognized in expanded circumscriptions, based on molecular phylogenetic findings ...

Senecio tauricus (Asteraceae) was described as an endemic species restricted to the mountain plateaus (yailas) of the Crimean Peninsula, growing only in meadow-steppe plant communities. The species status for this taxon ...

З використанням світлового та сканувального електрон-ного мікроскопів досліджено пилкові зерна Linnaea borealis. Встановлено, що пилкові зерна 3(4)-борозно-орові, еліпсоїдальні, сфероїдальні або сплющено-сфероїдальні за ...

Recent molecular phylogenetic results demonstrated that the genus Inula in its traditional circumscription is polyphyletic and its type, I. helenium, belongs to a clade phylogenetically distant from the clade containing ...

Following our recent lectotypification (with a specimen from G-DC) of the name Senecio praealtus Bertol. var. borysthenicus DC. validated by de Candolle based on Andrzejowski's and Besser's specimens from Ukraine, we ...

Pollen morphology of four species belonging to four genera of the tribe Cymbarieae and two species of Lindenbergia of the tribe Lindenbergieae (Orobanchaceae) was studied using light and scanning electron microscopy. ...

Current and historical views on taxonomy and nomenclature of Pontic-Mediterranean coastal and some Australasian taxa of Salsola (Chenopodiaceae) are analyzed. Taxonomic identity and nomenclature of several names applied ...

Following recent molecular phylogenetic findings and subsequent proposals on re-circumscription of genera earlier subsumed under Anemone sensu lato (Ranunculaceae), the genus Knowltonia is accepted here in an expanded ...
