Terellia ptilostemi sp. n., a previously unknown peculiar species of the genus Robineau-Desvoidy, 1830 is described based on holotype and large series paratypes reared from Ptilostemon rhiphaeus (Pau & Font Quer) Greuter (Asteraceae, Cardueae) in Tetouan Chefchaouen Provinces Western Morocco. The new has phallus glans typical for serratulae group, but an extremely uncommon wing pattern four...

Invasive species have great ecological and economic impacts and are difficult to control once established, making the ability to understand and predict invasive behavior highly desirable. Preemptive measures to prevent potential invasive species from reaching new habitats are the most economically and environmentally efficient form of management. Darwin's naturalization hypothesis predicts that...

The value of root and rhizome anatomy for the taxonomic characterisation of 59 species classified into 34 genera and 12 subtribes from the Asteraceae tribes Cardueae and Cichorieae was assessed. In addition, the evolutionary history of anatomical characters was reconstructed using a nuclear ribosomal DNA sequence-based phylogeny of the Cichorieae. Taxa were selected with a focus on pharmaceutic...

Lamyropsis (Charadze) Dittrich (Asteraceae) was erected to generic rank and clearly de"ned by Dittrich (1971). It is a member of tribe Cardueae Cass. subtribe Carduinae Dumort. and most closely related to the genera Cirsium and Ptilostemon. It currently comprises a total of 8 perennial species distributed from S Europe eastwards to Central Asia (Bremer, 1994). The morphological links of the gen...

The current investigations suggest the segregation of Jurinea cartilaginea from Jurinea, and its placement among Centaureinae. Molecular studies, based on the nuclear ribosomal internal transcribed spacers (nrITS), chromosome number data and pollen morphology, support the morphological results. Based on these results, J. cartilaginea is related to and, therefore, transferred to the genus Karvan...
