Geranium bicknellii is a species of geranium known by the common names Bicknell's cranesbill and northern cranesbill. It is native to much of the northern half of North America, where it can be found in a number of forest and woodland habitats. This is an annual or biennial herb which grows hairy stems up to about half a meter long. It may be erect or lie near the ground. Each leaf is several centimeters long and wide and is divided into several lobes, each of which may have smaller lobes or teeth. Flowers grow singly or in pairs and have pointed sepals and small lavender petals, each with a notch in the tip. The fruit has a rounded body with a long, straight style about 2 centimeters in length and tipped with a small beak.
Geranium bicknellii is a fire-adapted species, occurring most abundantly in recently burned forests. The seeds remain dormant while buried in the forest floor, sometimes for centuries, until a fire removes the organic litter and exposes the seeds to sunlight. The geraniums will germinate, bloom, and set seed profusely for several years after the fire, until other plants grow large enough to shade them out. The new seeds will then lie dormant in the soil, waiting for the next fire. [3]
The leaves of this species and some related species are somewhat difficult to distinguish from those of some plants in the family Ranunculaceae , particularly members of the genera Aconitum and Delphinium . They have also been confused with members of the genus Ranunculus , which is also part of that family, such as the meadow buttercup, Ranunculus acris . As the species from this family with a similar leaf shape are toxic to ingest or sometimes even touch, especially in the case of Aconitum species, it is possible that this is an example of mimicry designed to reduce herbivory. However, it may simply be accidental, due to adaption to conditions. As the family Ranunculaceae is especially ancient, other families have had quite a lot of time to mimic their characteristics via selection by herbivory. [4] [5]
Aconitum, also known as aconite, monkshood, wolfsbane, leopard's bane, devil's helmet, or blue rocket, is a genus of over 250 species of flowering plants belonging to the family Ranunculaceae. These herbaceous perennial plants are chiefly native to the mountainous parts of the Northern Hemisphere in North America, Europe, and Asia, growing in the moisture-retentive but well-draining soils of mountain meadows.
Ficaria verna, commonly known as lesser celandine or pilewort, is a low-growing, hairless perennial flowering plant in the buttercup family Ranunculaceae. It has fleshy dark green, heart-shaped leaves and distinctive flowers with bright yellow, glossy petals. Native to Europe and Western Asia, it is now introduced in North America, where it is known by the common name fig buttercup and considered an invasive species. The plant is poisonous if ingested raw and potentially fatal to grazing animals and livestock such as horses, cattle, and sheep. For these reasons, several US states have banned the plant or listed it as a noxious weed. It prefers bare, damp ground and is considered by horticulturalists in the United Kingdom as a persistent garden weed; nevertheless, many specialist plantsmen, nursery owners and discerning gardeners in the UK and Europe collect selected cultivars of the plant, including bronze-leaved and double-flowered ones. Emerging in late winter with flowers appearing late February through May in the UK, its appearance across the landscape is regarded by many as a harbinger of spring.
Ranunculaceae is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide.
Ranunculus is a large genus of about 1750 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots.
Caltha is a genus of rhizomatous perennial flowering plants in the family Ranunculaceae, to which ten species have been assigned. They occur in moist environments in temperate and cold regions of both the Northern and Southern Hemispheres. Their leaves are generally heart-shaped or kidney-shaped, or are characteristically diplophyllous. Flowers are star shaped and mostly yellow to white. True petals and nectaries are missing but the five or more sepals are distinctly colored. As usual in the buttercup family there is a circle of stamens around free carpels.
Ranunculus sceleratus known by the common names celery-leaved buttercup, celery-leaf buttercup, and cursed buttercup is a species of flowering plant in the buttercup family Ranunculaceae. It has a circumpolar distribution in the northern hemisphere, native to temperate and boreal North America and Eurasia, where it grows in wet and moist habitats, including ponds and streambanks.

There are two varieties; Geranium carolinianum var. carolinianum and the Geranium carolinianum var. sphaerospermum. This is a summer or winter annual herb. It can be considered invasive depending on the region, when it is found in the United States it is considered to be native.
