INTRODUCTION. 
In this seventh number of the series the author as usual presents 
descriptions of new and old species in several families. The only 
group treatment is that of the Artocarpoideae-Brosimeae of the 
family Moraceae, in which the genera Piratinera and Brosimum are 
redescribed as distinct and their species listed with description where 
needed.
