Herbs with opposite, entire leaves. Flowers usually in an inflorescence. Flowers 4-9-merous. The corolla is fused together and stamens are fused with the corolla and alternate with the lobes.

Herbs or undershrubs with lobed or compound usually stipulate leaves. Flowers regular or slightly zygomorphic, hermaphrodite and in five parts. Stamens usually in 2 whorls, sometimes some are sterile, filaments are united at the base. The ovary is superior, usually lobed and with a long beak ending in free stigmas. Fruit a lobed capsule, usually opening septicidally from base to apex.

Rosetted or sprawling plants with small cupped white or pink flowers of five petals and ten stamens, leaves round to kidney-shaped, deeply divided on long stalks. Fruits splitting from the base while still joined at the apex, then curling up like springs, detaching suddenly to carry the seed some distance away. The position of hairs on leaf stalks is important for recognition of species.


Differs from Geranium species in having the two upper petals larger than the others and always slightly separated from them. There is a nectar-spur at the base of the calyx. Three to eight of the ten stamens have anthers.


Ferns characterised by repeated forkings of the rachis. The frond is capable of indefinite growth.

Fern or fern-ally


Herbs and shrubs, petals unevenly spaced (two above, three below, or all on one side like a fan). Stigma covered by a hood (indusium).

Bushy shrublets, flowers blue, buds conspicuously hairy.


Winged petals, two above, three below, spreading from a tube enclosing the style with hooded stigma rising above a cylinder of erect stamens.


Fan-flowers are bushes to mat-plants, flowers arise from leaf bases, usually blue and hemispherical, with petal bases that are white or yellow.
