2. PLANERA J. F. Gmel. Syst. 2: Part i, 150. 1791. 



Trees, similar to the elms, the flowers monoecious or polygamous, unfolding with the

 fect ones in the axils of leaves of the year. Calyx 4-5-cleft, campanulate, persistent, the 

 lobes imbricated. Filaments filiform, straight, exserted. Ovary stalked, ovoid, slightly 

 compressed, i-celled. Styles 2, spreading, stigmatic along the inner side. Fruit nut-like;
