Stamens 10 (sometimes only 5 in No. 2), all with perfect anthers, the 5 

 longer with glands at their base (alternate with the petals). Styles smooth 

 inside in fruit when they separate from the axis. Stems forking. Peduncles

1. G. macillatum, L. (WILD CRANESBILL.) Stem erect, hairy; 

 leaves about 5-parted, the wedge-shaped divisions lobed and cut at the end ;

 and cut into numerous oblong-linear lobes ; peduncles and pedicels short ; 

 sepals awn-pointed, as long as the emarginate (pale rose-color) petals ; carpels 

 hairy ; seeds ovoid-oblong, very minutely reticulated. Barren soil and waste 

 places : common. May - Aug. Depauperate forms, except by the seeds, are 

 hardly distinguishable from 



3. G. DISSECTUM, L. ( CUT-LEAVED C.) More slender and spreading, 

 with narrower lobes to the leaves, and smaller red-purple petals notched at the
