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.

Seed germination in the Sicilian subspecies of Dianthus rupicola Biv. (Caryophyllaceae)

Abstract Five populations belonging to three subspecies of Dianthus rupicola Biv. (D. rupicola subsp. rupicola, D. rupicola subsp. aeolicus, and D. rupicola subsp. lopadusanus) and growing in different geographical areas of Sicily were tested for seed germination at various temperatures. All populations showed high germination rates with an optimum temperature between 15°C and 25°C. Efficient seed germination might contribute significantly to the preservation of these subspecies which are currently exposed to several environmental threats.
