Caratteristiche bioclimatiche della Sicilia

Abstract The results of a bio-climatic study regarding the Sicilian territory is given. On the basis of thermometric and pluviometric data, some indexes proposed by Rivas-Martinez have been produced for 61 localities of the island. In particular, the indexes utilized for the bio-climatic classification are the following: It (index of thermicity), Iov (ombro-thermic index) and Iovc (compensated ombro-thermic index). Besides, for the individuation and delimitation of the bio-climatic belts and relative thermo-types and ombro-types other data, as average annual temperatures, average annual precipitation, geomorphology and relative climax vegetation, have been considered. On the whole, the bio-climatic belts occurring in Sicily are: inframediterranean, thermomediterranean, mesomediterranean, supramediterranean, oromediterranean and crioromediterranean. The correlations between the vegetation and bio-climate are examined too.

Astragalus kamarinensis (Fabaceae), a New Species from Sicily

Astragalus kamarinensis C. Brullo, Brullo, Giusso, Miniss. & Sciandr. sp. nova (Fabaceae) is described and illustrated from Sicily. It grows exclusively on sandy soils, near the ruins of Kamarina, located in the southern part of Sicily. Morphologically, it shows close relationships with A. Stella, A. raphaelis and A. tribuloides, all belonging to A. sect. Sesamei. Several morphological features, chiefly regarding the flowers, legumes and seeds, as well as the micromorphology of the pod indumentum and seed coat, allow to well distinguish this species from the other taxa in the section. A phenetic analysis based on the morphological characters supports our taxonomic conclusions.

A new species of Brassica sect. Brassica(Brassicaceae) from Sicily

Among the suffruticose cabbages of Brassica sect. Brassica, a new species from Sicily, named B. raimondoi, is described and illustrated. It is a chasmophyte restricted to some steep limestone cliffs near Taormina (NE Sicily) and is morphologically related to B. incana, with which it shares densely hairy, broad, amplexicaul leaves and winged petioles, but differs principally in its white corolla, larger floral pieces, more developed stigmatic papillae, shorter siliquae with keeled valves and a smaller, seedless beak, smaller seeds differing in testa microsculpture. A key for the identification of the currently known Sicilian taxa of the section is provided.

RUTA LAMARMORAE (RUTACEAE) , A NEW SPECIES FROM SARDINIA

A new species from Sardinia occurring on the Gennargentu massif, Ruta lamarmorae (Rutaceae) , is described and illustrated. Its relationships with R. corsica , a species widespread in the Corsican mountains, are examined.

Three new species of Allium sect. Codonoprasum from Greece

Abstract Three new species of Allium from Greece are described. They are A. dirphianum, A. phitosianum and A. rausii, all included in A. sect. Codonoprasum. Morphology, karyology, distribution and relationships are examined for each of them.

Cytotaxonomical notes on some rare endemic species of Allium (Alliaceae) from Greece

Abstract Five Greek endemic species of Allium (A. meteoricum, A. parnassicum, A. pilosum, A. luteolum and A. frigidum) are examined. The study, based on field and herbarium investigations, allowed to better define the morphology, karyology and chorology of these critical taxa as well as their relationships.

Taxonomic Notes on the Genista ephedroides Group (Fabaceae) from the Mediterranean Area

Abstract.  A revision of the taxa belonging to the Genista ephedroides group (Fabaceae, Cytiseae) occurring in the Tyrrhenian area is presented. The study, carried out on the basis of the literature, herbarium material, and field and karyological investigations, allows the recognition of 13 taxa. Eight are already known: G. cilentina Vals., G. demarcoi Brullo, Scelsi & Siracusa, G. dorycnifolia Font Quer, G. ephedroides DC., G. gasparrinii (Guss.) C. Presl, G. numidica Spach, G. tyrrhena Vals., and G. valsecchiae Brullo & De Marco, and five are new to science. Genista bocchierii Bacch., Brullo & Feoli Chiapella, G. insularis Bacch., Brullo & Feoli Chiapella, G. insularis subsp. fodinae Bacch., Brullo & Feoli Chiapella, and G. ovina Bacch., Brullo & Feoli Chiapella are described from Sardinia, Italy, while G. tyrrhena subsp. pontiana Brullo & De Marco is described from the Pontine Archipelago of Latium, Italy. Karyologically, most of the taxa are characterized by the somatic number 2n = 48 (G. bocchierii, G. cilentina, G. demarcoi, G. dorycnifolia, G. gasparrinii, G. tyrrhena subsp. tyrrhena, G. ephedroides, G. valsecchiae, G. insularis), with accessory chromosomes occasionally yielding higher counts. In addition to 2n = 48, the new report of 2n = 44 is noted for the new species G. ovina. A new count of 2n = 48 is reported for G. tyrrhena subsp. tyrrhena, whereas higher counts (2n = 48 + 0–2B, 72, 96) are reported for the new subspecies G. tyrrhena subsp. pontiana. For each examined taxon, notes are given on the nomenclature, karyology, ecology, and chorology, while a detailed iconography is lacking only for G. numidica and G. dorycnifolia. An analytical key for the G. ephedroides group is presented. Lectotypes are designated for G. numidica and Spartium gymnopterum Viv.

Taxonomic revision of the Koeleria splendens C. Presl group (Poaceae) in Italy based on morphological characters.

Abstract The Italian populations of Koeleria splendens C. Presl, critical group of the Mediterranean flora, are examined from the taxonomic and nomenclatural viewpoints. On the basis of literature data, herbarium investigations and field surveys, many morphologically well-differentiated taxa have been recognized. This group is widespread in the Italian peninsula and Sicily, where it is represented by the following units: K. splendens C. Presl, with four subspecies [subsp. splendens, subsp. grandiflora (Bertol. ex Schultes) Domin, subsp. brutia Brullo, Gangale & Uzunov, and subsp. ophiolitica subsp. nova], K. lucana sp. nova, K. subcaudata (Ascherson & Graebner) Ujhelyi, K. australis Kerner, K. callieri (Domin) Ujhelyi, and K. insubrica sp. nova. As concerns their distribution, both K. splendens and K. lucana are endemic to the Italian territory, while the other species occur also in some eastern Mediterranean countries. The taxonomic position of K. lobata, recently treated by some authors as a synonym of K. splendens, is also examined. A phylogenetic analysis was performed using morphological characters. Finally, a detailed iconography of the main morphological features and an analytical key of the Italian taxa (K. lobata included) are given.

A New Autumn-Flowering Species of Allium (Alliaceae) from Croatia

Here we describe Allium telmatum Bogdanović, Brullo, Giusso & Salmeri, a new species of Allium sect. Codonoprasum from North Dalmatia (Croatia). Its chromosome number (2n = 32), karyotype, leaf anatomy, ecology and taxonomical relationships are examined. Several features, such as phenology (flowering in autumn), occurrence in coastal salt marshes, tetraploid chromosome number, and morphology, indicate that it is most closely related to the Tyrrhenian species Allium savii. On the basis of our herbarium survey, we present here a distribution map of the autumn-flowering species of Allium sect. Codonoprasum in the Mediterranean area.
