THE GERANIUM FAMILY. 



Wood Sorrel, Oxalis Acetosella. A very small herb 

 with clover-like leaves and numerous red-veined, delicate

 pretty, large, violet-blue flowers in loose corymbs. The 

 blood-red cranesbill (ft sanguineum) is a spreading herb 

 with five- or seven-parted leaves. Flowers on axillary

 purple with conspicuous crimson veins. All these are fine 

 for rockeries in open woods and shrubberies, or on grassy 

 banks of rivers and lakes, in sunny or half-shady posi-

 (G-.argenteum) is a neat little Alpine plant with almost pel-
