Our results highlighted a diploid status (2n = 2x = 22) for all the three involved taxa and a higher morphological similarity between C. brutius and C. affinis, which are also completely allopatric (but collectively sympatric with C. defloratus subsp. carlinifolius). The names Carduus affinis Guss., C. affinis var. brutius Fiori, C. affinis var. vulturius Fiori and C. affinis f. pollinensis Fiori were typified. At the present state of knowledge, a subspecific status seems the most appropriate for C. brutius, as C. affinis subsp. brutius. This taxon can be regarded as schizoendemic, restricted to southern Italy (Montea-Caramolo mountain area, Calabria).

First, using this index we are able to identify the amino acid property - among the 530 analyzed - that best correlates with the organization of the genetic code in the set of amino acid permutation codes. Considering, then, a model suggested by the coevolution theory of the genetic code origin - which in addition to the biosynthetic relationships between amino acids took into account also their physicochemical properties - we investigated the level of optimization achieved by these properties either on the entire genetic code table, or only on its columns or only on its rows. Specifically, we estimated the optimization achieved in the restricted set of amino acid permutation codes subject to the constraints derived from the biosynthetic classes of amino acids, in which we identify the mo...

It includes new records, confirmations and status changes to the Italian administrative regions for taxa in the genera Acer, Alchemilla, Andrachne, Bromus, Clinopodium, Colchicum, Damasonium, Erodium, Festuca, Hieracium, Hyparrhenia, Ipomoea, Linaria, Lolium, Narcissus, Ranunculus, Sisymbrium, Stipa, Valerianella, Vicia, and Zannichellia. New combinations in the genus Ziziphora (Z.sardoa and Z.corsica) and the new subspecies Ulmusminor susbp. canescens are proposed. Furthermore, the name Calaminthaalpinavar.sardoa is here lectotypified. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.
