GERANlACEAE (GERANIUM FAMILY) 



Plants with perfect regular 5-merous hypogynous flowers. Sepals imbricated 

 in the bud, persistent. Glands of the disk 5, alternate with the petals. Stamens, 

 counting the sterile filaments, as many or commonly twice as many as the sepals. 

 Ovary deeply lobed; carpels 2-ovuled, l-seeded, separating elastically with their 

 long styles, when mature, from the elongated axis. Cotyledons plicate, incum- 

 bent on the radical. Our species herbs with lobed or divided stipulate leaves, 

 and astringent roots. 



1. Geranium. Stamens with anthers 10, rarely 5. The recurving bases of the styles or tails of 



the carpels in fruit naked inside. 

 '2. Erodium. Stamens with anthers only 5. Tails of the carpels in fruit bearded inside, often 



spirally twisted.

 Greek name, from ytpavos, a crane; the long fruit-bearing beak thought to 

 resemble the bill of that bird.)
