Building natural classifications for genera with complex morphological variations such as Centaurea needs the support of molecular analysis and knowledge character diversification. Here we use parsimony Bayesian analyses nuclear ribosomal ITS sequences to gain insight into sectional relationships evolution in sections Chartolepis, Cheirolepis, Cynaroides, Grosheimia, Microlophus, Paraphysis, Ph...

Achene morphology of 49 taxa of the genus Centaurea L. was studied in terms of 19 different characteristics. On the basis of the variation in these features, some sections, such as sect. Cyanus with hairy hilum, were separated. Despite various differences, C. leuzeoides and C. gilanica were categorized in the section Psephelloideae, a section with lots of character variations within its species...

A study of saprobic fungi occurring on the fynbos of the Western Cape Province of South Africa yielded four unknown Anthostomella species. A. proteae from Protea nitida, A. cynaroides from P. cynaroides, A. leucospermi from Leucospermum oleifolium, and A. brabeji from Brabejum stellatifolium are described as new. New records for South Africa include A. conorum from Leucadendron sp., Protea magn...

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 snake gourd genus, Trichosanthes, is the largest genus in the Cucurbitaceae family, with over 90 species. Recent molecular phylogenetic data have indicated that the genus Gymnopetalum is to be merged with Trichosanthes to maintain monophyly. A revised infrageneric classification of Trichosanthes including Gymnopetalum is proposed with two subgenera, (I) subg. Scotanthus comb. nov. and (II) ...
