cuius having a smooth beak. Geranium pusiUum has emargi- 

 nated petals, only five antheras, and its flowers are much 

 smaller, although also pale-red. The beak of the utrkulus 

 is not furnished with distant, but with thick crowded hairs. 

 G. pyrenaicum^ which is most nearly related to G. molle^ has 

 a perennial root, is much larger in all its parts, has also large 

 flowers, the petals of which are deeply cleft, and it has not a 

 bunchy utriculus. G. dissectum is distinguished by its pal- 

 mate, cleft leaves, the lobes of which are linear, and stand at 

 regular distances from each other ; the emarginated petals 

 are as long as the awned calyx : the beak of the utriculus is 

 furnished with shaggy hairs : the flower-stalks are shorter 

 than the stem-leaves. G. columbinum, on the other hand, 

 which is very like G. dissectum, has very long, wavering, 

 flower-stalks, stem-leaves of the same kind, large flowers, and 

 a smooth beak of the utriculus. 



The genus Geranium cannot be distinguished at first sight 

 from Erodium Ait. But the latter has among its ten fila- 

 ments, five that are unfruitful and abortive : the beak of the 

 utriculus is turned into a spiral shape, and is internally fur- 

 nished with hairs, which niay be most easily seen in E, cicu- 

 tarium, the most common species. Pelargonium Ait. has a 

 similar beak of the utricidus, but the corolla is irregular and 

 two-lipped : the nectary is in the bottom of the tubular calyx. 

 The diagnostic character of Geranium, therefore, is as fol- 

 lows : the corolla regular, ten fertile filaments, five nectaries 

 at the base of the filaments, and a straight beak of the utri- 

 culus, internally without hairs. The Geraniss constitute a 

 natural family, which stands between the Agruinae and Mal- 

 vaceae, (Anleit. ii. vid. 793.)
