(1) New Holland contains more than forty European phanerogamous plants.(2) The phanerogamic flora of the New Hebrides is mainly of the Malesian type both in floristic composition and structure of the vegetation.(3) Some plants, like ferns, although they are not phanerogamous (therefore lacking flowers and reproducing by means of spores), have been historically considered together with these.(4) In this area they were found seven sites inhabited for a total of 250 species related with phanerogamic flora.(5) Plants with flowers and leaves ( phanerogams and Latifoliae) appeared no earlier than the Cretaceous - in other words about 100 million years ago, long after the first protophasmids.(6) Unlike phanerogams , which undergo long-range dispersal by seeds (seed plants) or spores (ferns and mosses), lichens have two fundamentally different mechanisms of long-range dispersal.(7) It is known that, among the four spontaneous phanerogams colonising the sandy and muddy loose sea-bottoms of the Mediterranean Sea, i.e. Posidonia oceanica, Cymodocea nodosa, Zostera noltii and Zostera marina, mainly the Posidonia and the Cymodocea are the most frequent ones.
