Geranium. GERANIACE.E. 119 



Order XXV. GERANIACEtE. DC. The Geranium Tribe. 



Calyx of 5 persistent sepals, which are imbricated in aestivation. Corolla 5- 

 petalled, hypogynous or somewhat perigynous : petals alternate with the sepals, 

 distinct, unguiculate, twisted in imbrication. Stamens usually twice as many 

 as petals, and inserted with them ; some of them occasionally sterile : filaments 

 broad, somewhat monadelphous at the base. Ovary composed of 5 two-ovuled 

 carpels, placed alternate with the sepals round the base of an elongated axis 

 (gynobase). Styles cohering with the axis, free at the summit, stigmatose on 

 the inner side. Carpels dry, 1-seeded, distinct at maturity, and separating 

 from the axis by the twisting or curling back of the persistent style from the 

 base upwards, mostly dehiscent by the inner suture. Seeds without albumen. 

 Cotyledons convoluted and plaited. — Herbs or shrubby plants, commonly 

 strong-scented. Leaves palmately veined and usually lobed, mostly with 

 stipules. Flowers regular, or somewhat irrregular.

 cels an inch or more in length. Flowers about an inch in diameter. Sepals oblong or oval- 

 lanceolate, sparsely clothed, particularly about the margins, with long villous hairs, which are
