CV, TJRTICACEJ!, NETTLE FAMILY. 



This family, taken in the largest sense, includes very various 

 apetalous plants, with monoecious or dioecious flowers (except 

 in the Elm Subfamily), having a distinct calyx free from the 

 1-seeded (but sometimes 2-celled) fruit. Stamens as many as 

 the lobes of the calyx and opposite them, or sometimes fewer. 

 Inner bark generally tough. Leaves with stipules, which are 

 sometimes early deciduous. 



I. ELM SUBFAMILY. Trees, the juice not milky. Leaves 

 alternate, 2-ranked, simple; stipules small and falling early.
