axillary and solitary or clustered, regular or slightly irregular 
hypogynous, their parts in fives. Stamens 5 or 10, monadel- 
phous at the base. Carpels 5, each 2-ovuled, splitting away 
with their long styles when ripe from a central axis and thus 
scattering the seeds. 
I. GERANIUM, Tourn. 
Herbs, rarely shrubs. Leaves with stipules, opposite or 
alternate, usually cut or lobed. Flowers regular, on 1-2- 
flowered axillary peduncles. Sepals and petals 5. Stamens 
10, ripening in 2 sets. Ovary 5-lobed, 5-beaked ; stigmas 5. 
1. G. maculatum, L. Witp CRrANEsBILL, WiLp GERANIUM. 
Perennial, with an erect, hairy stem, 12-18 in. high. Leaves about 
5-parted, marked with pale blotches, the root-leaves long-petioled. 
Flowers large (1 in. or more in diameter), light purple, somewhat

II. PELARGONIUM, L’Her. 
Perennial herbs or shrubs. Leaves with stipules, scented.

sepals hollowed out below into a nectar-bearing tube extend- 
ing down the pedicel. The 2 upper petals different in size or 
shape from the other 3. Cultivated from the Cape of Good 
Hope. [Most of the species are commonly, though not quite 
correctly, called “geraniums.” Only a few of the commonest 
are here described. | 
1. P. peltatum, Ait. Ivy Geranium. Stems somewhat prostrate 
and trailing. Leaves somewhat peltate, smooth or nearly so. 
Flowers pink or white.
