THE BUTTERCUP FAMILY
 
The buttercup family is common in temperate and boreal regions of the Northern Hemisphere. These plants are usually herbs, but may also be vines or shrubs. The stems do not have spines or prickles. The stem leaves are alternate or occasionally opposite or whorled. The leaves can be simple or compound but are at least lobed in the majority of species. The margins may be entire or toothed. The flowers are in several different types of clusters, from solitary flowers to branched, unbranched or umbrella-like groups. The flowers are commonly lacking petals and have coloured sepals. One to several whorls of bracts may be present below the flowers. The ovary consists of several separate carpels which mature to form an aggregate fruit or berry. The aggregates may be of pods or of single-seeded fruits that resemble seeds.
 
TWOLEAF ANEMONE
 
  LATIN NAME:    Anemone quinquefolia var. bifolia
 
WHAT DOES IT LOOK LIKE?
 
Twoleaf anemone grows as tall as 30 cm from slender, horizontal rhizomes. The stems are erect and are covered in long hairs. A basal leaf may or may not be present. If present, the leaf has three to five leaflets. Below the stem are three, stalked bracts or leaves that are divided into three to five leaflets. The flowers are solitary. Each flower has five white stamens, no petals and 30 to 60 stamens. The fruits are aggregates of seeds. The seeds are slightly hairy but not woolly.
 
WHERE DOES IT GROW?
 
Twoleaf anemone grows in moist open woods and clearings.
 
WHERE IS IT FOUND IN SASKATCHEWAN?
 
This plant is found in east-central Saskatchewan in the Boreal Transition, Mid-Boreal Upland, and Mid-Boreal Lowland ecoregions.
 
WHY IS IT RARE?
 
Twoleaf anemone is threatened because of rarity in Saskatchewan. It is regionally restricted to the eastern part of the province. Some local populations are small and some larger. Possible threats have been identified for this species.
 
HOW TO IDENTIFY TWOLEAF ANEMONE
  * Are there three, stalked leaves on the stem?
* Are the sepals white and the petals absent?
* Are the fruits slightly hairy (but not woolly)?
* Did you find it in east-central Saskatchewan?
If you answered yes to all of these questions, you may have found twoleaf anemone!
