Description

Genus Geranium

Annual or perennial herbs. Leaves usually alternate, stipulate , variously divided . Peduncles (1-) 2-flowered. Flowers often showy, regular, usually 5-merous. Petals alternating with 5 nectiferous glands . Stamens (5-) 10, staminodes occasional. Carpels usually 5, adnate , separating septifragally from the central axis at maturity. Ovary 5-lobed. Fruit schizocarpic, of 5 mericarps which remain attached to an elastically coiling stylar axis upwards; mericarps without apical pits.

A genus of c. 400 species, mainly distributed in the temperate zone of N. Hemisphere, but also in the tropics. Represented in Pakistan by 22 species. The large flowered perennials are difficult to key out satisfactorily unless there is ample information on the nature of the underground parts, flower colour, shape and size of the leaves and the fruits. In the key that follows, I have used the following terminology: segments for primary division of leaves; lobes for secondary division . The sepal length excludes the awn . The beak length (in fruit) excludes the styles.[1]
