abstract

Preliminary phytosociological and cenological considerations about the presence of Styrax officinalis in the area of Cornicolani Mounts (central Latium). A preliminary study on the distribution and cenology of Styrax officinalis in central Latium is presented in this paper. This species exhibits a primary role both in the undergrowth of the termophilous oak-woodlands and in the shrubland communities involved in the secondary reforestation dynamics. In particular this species represents the guide element of a typical tall-shrubland community type together with Cercis siliquatrum, Pistacia terebinthus and Acer monspessulanum. Although the extremely restricted distribution area of this species in Italy and its peculiar biogeographical role, italian Styrax officinalis communities are still not considered in any of the “Habitat type” included in the Annexe I of the 43/92/EEC Habitat Directive.
