The genus Baloghia lives in the islands of SE Asia today, but it lived also in Europe in the Tertiary. The genus Actinidia inhabits also SE Asia in present times, but its remains were found in Europe, from the Eocene till the Pliocene. A very well preserved fossil leaf of the species living today in Asia, came to light from the lower Oligocène formations in California. The members of the genus Sloanea now range alike in the islands of Central America and SE Asia, — having been present also in Europe in the Upper Eocene. The genus Scolopia lives today in Africa, and in SE Asia ; the genus Trimeria in South Africa; the genera Banara and Tetrapteris in South America, — but they had been members of the European flora already in the Upper Eocene. For the recent distribution of disjunct genera, AXELROD'S archipelago theory submits an acceptable explanation. He incorporated in his theory the latest results of paleobotanies and allied sciences. An archipelago of an oceanic character in the area of Central Europe had already been presupposed by STAUB, UNGER and ETTINGSHAUSEN, and for France by SAPORTA, to explain the presence 01 several tropical genera found in the Tertiary.
