THE FAMILY OF GERANIUMS OR CRANESBILLS. 



Distribution. A family of 20 genera and 750 species, found chiefly in 

 temperate and hot climates. Many of the species have astringent and aromatic 

 properties. Oxalic acid is obtained from the Oxalidaceae. The Geraniums and 

 Pelargoniums are well-known garden flowers. Most of the latter are natives of 

 the Cape of Good Hope. This family is very nearly allied to the Linaceae.
