Low effective allele numbers (3.07-6.67) and extremely low effective population sizes (35.4-102.9) were detected in both reforestation stands, probably due to an inappropriate forester seed collection strategy limited to a few mother trees. Analysis of simulated progenies showed that optimal sampling size to obtain seed collections genetically similar to the origin population should range from 20 to 50 individuals, but could be different between the two regions, being higher in the more genetically diverse Andalusia

The taxonomic treatment of Capparis in this area required study because of some incompletely known taxa and deviating forms. Based on morphological and distributional investigations carried out on historical and recent herbarium collections, four species are recognised in New Caledonia: C. spinosa, belonging to sect. Capparis; C. quiniflora, belonging to sect. Monostychocalix; and C. parvifolia and C. artensis, both belonging to sect. Busbeckea. Capparis spinosa is represented by subsp. cordifolia, a taxon widespread in several Pacific islands, for which only scanty collections from the Loyalty Islands have been examined. Capparis quiniflora, widely distributed from the Malesian Region to Australia, is present along the coast and lowlands of New Caledonia on various substrata up to c. 250 m elevation. Capparis parvifolia is endemic to Mont Kaala, North Province of New Caledonia, where it is reported on ultramafic substrata from c. 100 to 800 m. Capparis artensis, known from New Caledonia and Vanuatu, is widespread prevalently on ultramafic substrata from sea level to c. 700 m. A nomenclatural novelty, C. artensis var. dielsiana comb. et stat. nov., is here proposed and seven lectotypes are designated. A key to species is provided, along with descriptions, distributions and autecological data. Capparis loranthifolia var. bancroftii, formerly recorded from a single mountain range of New Caledonia, is excluded from the flora of the island.

Pollino. In Italy this species was so far reported only from the Alps and a few localities of centraI Apennines. Therefore the finding on Mt. Pollino largely widens its distribution southwards in the Italian Peninsula. As regards Europe, J. sabina reaches lower latitudes only in southern Spain. The Authors stress the phytogeographical significance of the sites, which are characterized from the floristic and ecological viewpoint.

In the present work the levels of genetic diversity and differentiation between artificial stands of Quercus ilex and the adjacent natural stands are assessed with nuclear microsatellites. Also, it was possible to analyse the natural population used as seed source for one of the reforestations studied. The levels of genetic differentiation between natural and artificial stands and the decrease of genetic diversity from the seed origin population to the reforestation are discussed in relation to the transference of seed among provenance regions and to the seed collection strategy (number of trees used for sampling seeds).
