- 15 - Colchis approximates the climate of the Lower Pliocene, but di- fers in lower minimum temperatures Under these conditions, many species of the above genera are successfully cultivated on the Colchis seashore, as for example tea, citruses, laurels, bamboos, palms and many others. The total number of species introduced in- to the dendroflora of Abkhazian coast exceeds 1000. Thus, many of the above plants were actually returned to their "native coun-try". All this permits us to assume that the most useful introductions for coastal Colchis will be those from just this ecological group of plants, from the mountainous humid-subtropical and warm-temperate areas of East Asia, as well as from the Mediterranean region and its analogues. An inspection of the dendrofloral collections in the Sukhumi Botanical Garden, as well as in numerous Sukhumi parks and gar-dens will provide an idea of how successfully these plants develop on the seashore of Abkhazia.
