 Fatoua, Sloetia, Conocephalus, Oudrania, Artosarpus, Parartocarpiis, 

 Antiuris and Sparattosycc, that is, twenty genera. Brazil possesses 

 an equal number of which two-thirds are peculiar to it. Ficus, 

 the only genus observed spontaneous in all parts of the world, is 

 rare in Europe and exists only in the south where it is represented 

 by a single species, F. Carica} In Africa it extends to the Cape, 

 and in Asia ascends to Japan. In the two Americas its geographical 

 range is over 60 degrees, and in the Old World nearly 80. The 

 other Artocarpeœ are confined to the more tropical regions. Oud- 

 rania and Conocephalus extend to the Asiatic temperate zone, and 

 in the warmest parts of Mexico are found, besides Figs, a Sahagunia 

 and a Cccropia. The Moreœ extend further both north and south, 

 for Broussonetia reaches the north of China ; Madura inhabits the 

 United States, and both endure the open climate of our country, 

 as also many Mulberries. Paratrophis heterophylla is a native of 

 New Zealand. Morus alia grows wild in Mongolia, and 31. rubra 

 as far as Canada. The genera of this family which include the 

 wildest species belong to the Ulmece series. There are species of 

 Celtis as far as the north of China and Japan. 2 The Elms have 

 the most northern range whether in America 3 or in Asia and 

 Europe. 4 In this last part of the world, besides Figs, we meet 

 with the genera Ulmus, Celtis, Abelicea, and Ilumulus in the wild 

 state, and introduced, the genera Morus, Broussonetia, Madura, 

 Oudrania, Planera, and Cannabis thought to be of Asiatic origin. 5 



The series which we admit in this family are distinguished from 

 one another by the following characters :
