1 to 18. I. 



Common on the Continent and in North America. Recorded 

 from the West Indies. 



Obs. — Distinguished from Lo^jJiocoIea cnspidata, Limpr. and 

 LopJt. JieferojjJi'i/lIa (Schrad.) by its dioicous inflorescence. LojjJio- 

 colea latifolia, Nees (Z. Hookenana, Nees) is a variety with darker 

 green leaves of a firmer texture, usually growing in damper 

 situations, but I cannot fix upon any character to separate it from 

 the type.
