A short synopsis of the tribe Alysseae (Brassicaceae) in Croatia with some taxonomic novelties.

Plazibat, M.: A short synopsis of the tribe Alysseae (Brassicaceae) in Croatia with some taxonomic novelties. Nat. Croat., Vol. 18, No. 2, 401–426, 2009, Zagreb. The tribe Alysseae consists of a significant group of plants found in the Croatian native flora. It comprises seven genera: Alyssoides, Alyssum, Aurinia, Berteroa, Clypeola, Degenia and Fibigia with a certain number of various endemics. Relationships, distribution and taxonomic limits of the taxa from the genera Alyssum and Aurinia were unclear and controversial as a result of polymorphism. Therefore, revision and analysis of comprehensive plant material has been done using a biosystematic and chemotaxonomical approach. Differences between taxa from the genera Alyssum and Aurinia are clearly detected. In this study two new varieties are described: Alyssum desertorum Stapf var. socolacicum Plazibat, var. nov. and A. serpyllifolium Desf. var. metajnae Plazibat, var. nov. The following new combinations are proposed: Aurinia leucadea (Guss.) K. Koch subsp. media (Host) Plazibat, stat. et comb. nov., Aurinia leucadea subsp. scopulorum (Ginzb.) Plazibat, comb. nov., A. petraea (Ard.) Schur subsp. corymbosa (Griseb.) Plazibat, stat. et comb. nov. and A. petraea subsp. microcarpa (Vis.) Plazibat, comb. nov. Presented revision shows that twenty three taxa of the tribe Alysseae grow in Croatia: Alyssoides utriculata, Alyssum alyssoides, A. montanum subsp. gmelinii, A. montanum subsp. molliusculum, A. montanum subsp. montanum, A. montanum subsp. pagense, A. murale, A. repens subsp. transsilvanicum, A. serpyllifolium var. metajnae, A. simplex, A. strigosum, Aurinia leucadea subsp. leucadea, A. leucadea subsp. media, A. leucadea subsp. scopulorum, A. petraea subsp. microcarpa, A. saxatilis subsp. orientalis, A. saxatilis subsp. saxatilis, A. sinuata, Berteroa incana, B. mutabilis, Clypeola jonthlaspi subsp. jonthlaspi, Degenia velebitica and Fibigia triquetra.
