108. NATURAL HISTORY OF PLANTS. 



streblus, Cardioyyne, Uromorns and Pseudomoriis. Among the 

 Artocarpeœ, be established the new genera Ogcodcia and Sparatto- 

 syce, and admitted the genera posterior to the work of Trecul de- 

 scribed by Miquel under the name of Naucleopsis, by Liebmann 

 under that of Sahagunia, and by F. Allemao under those of Soaresia 

 and Acanthinophyllium. He likewise reincludes in this group the 

 older genera Bayassa, Maquira of Aublet, and Mt/rianthus of 

 Palisot de Beauvois, with Bosqueia which remained long un- 

 published in the herbarium of Dupetit-Thouars, and which, in our 

 opinion, 1 could not be separated from this family in which we have 

 just ~ established the five genera Parartocarpus, Helianthostylis, 

 Scypkosyce, Lanessania, and Pseudosorocea. Finally, the Cannabinece 

 comprising the two genera Cannabis and Humulus, with three or four 

 species only, and the number of genera we preserve in the other 

 series, being eleven for Ulmece, twenty for Moreœ, and thirty-two for 

 Artocarpeœ, we. arrive at a total for the entire family of Ulmaceœ, of 

 sixty-five genera comprising about a thousand species. 



They are distributed over a considerable extent of the globe. 

 Celtis and Ficus, for example, belong to all parts of the world ; 

 Trcma and Moms to most warm regions ; Uhnus to all parts of the 

 northern hemisphere. Three other genera, Dorstenia, Trymatococcus, 

 and Humulus, 3 are common to both worlds. To America belong the 

 twenty-three genera Planera, Ampelocera, Madura (?), Tropins, 

 Cecropia, Coussapoa, Pourouma, Bayassa, Olmedia, Pseudolmcdia, 

 Acanthinophyllum, Noyera, Perebca, Maquira, CasUlloa, Nauckopsis, 

 Helicostylis, Helianthostylis, Lanessania, Piratinera, Sahayunia, 

 Sorocea, and Pseudosorocea. The remaining thirty-five belong to the 

 old world. Some of them are found only in Africa; Chœtacme 

 grows at the Cupe of Good Hope; Maillardia, Cardioyyne, Ampalis, 

 Bosqueia, belong to the continent or eastern isles ; S'cyphosyce, 

 Treculia, Musnnga, Myrianfims, and Dicranostachys, are observed only 

 on the tropical western coast. The other types are most numerous 

 in Tropical Asia and Australia on the one hand, and on the other in 

 tropical South America. To the former belong exclusively Gironniera, 

 Parasponia, Jphananlhc, Holoptelca, Diplocos, Piiyllocldamys, Streblus,
