Ranunculaceae in the context of "Lesser celandine"

Ranunculus /ræˈnʌŋkjʊləs/ 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.

The genus is distributed worldwide, primarily in temperate and montane regions. The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup Ranunculus repens, which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup Ranunculus bulbosus and the much taller meadow buttercup Ranunculus acris. In ornamental gardens, all three are often regarded as weeds.

Anemone (/əˈnɛməniː/) is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all regions except Australia, New Zealand, and Antarctica. The genus is closely related to several other genera including Anemonoides, Anemonastrum, Hepatica, and Pulsatilla. Some botanists include these genera within Anemone.

Aquilegia, commonly known as columbines, is a genus of perennial flowering plants in the family Ranunculaceae (buttercups). The genus includes between 80 and 400 taxa (described species and subspecies) with natural ranges across the Northern Hemisphere. Natural and introduced populations of Aquilegia exist on all continents but Antarctica. Known for their high physical variability and ease of hybridization, columbines are popular garden plants and have been used to create many cultivated varieties.

Aquilegia typically possess stiff stems and leaves that divide into multiple leaflets. Columbines often have colorful flowers with five sepals and five petals. The petals generally feature nectar spurs which differ in lengths between species. In North America, morphological variations in spurs evolved to suit different pollinators. Some species and varieties of columbines are naturally spurless. In cultivation, varieties bearing significantly altered physical traits such as double flowering are prevalent.

Commonly known as hellebores (/ˈhɛləbɔːrz/), the Eurasian genus Helleborus consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Many hellebore species are poisonous.

Despite common names such as winter rose, Christmas rose, and Lenten rose, hellebores are not closely related to the rose family (Rosaceae).

Ranunculus repens, the creeping buttercup, is a flowering plant in the buttercup family Ranunculaceae, native to Europe, Asia and northwestern Africa. It is also called creeping crowfoot and (along with restharrow) sitfast.

Ranunculus bulbosus, commonly known as bulbous buttercup or St. Anthony's turnip, is a perennial flowering plant in the buttercup family Ranunculaceae. It has bright yellow flowers, and deeply divided, three-lobed long-petioled basal leaves.

Ranunculus acris is a species of flowering plant in the family Ranunculaceae, and is one of the more common buttercups across Europe and temperate Eurasia. Common names include meadow buttercup, tall buttercup, common buttercup and giant buttercup.

Aconitum (/ˌækəˈnaɪtəm/), 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, frequently toxic 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.

Most Aconitum species are extremely poisonous and must be handled very carefully. Several Aconitum hybrids, such as the Arendsii form of Aconitum carmichaelii, have won gardening awards—such as the Royal Horticultural Society's Award of Garden Merit. Some are used by florists.
