Description
 
 

Sulphur cinquefoil is a 16 to 32 tall, erect, perennial forb that rises on 1 to 3 stems from a thick caudex. It can form large clumps.

The stems are erect, stout, unbranched below the inflorescence, and covered with both glandular and non-glandular hairs.

The leaves are alternate. Lower leaves are on hairy stalks up to 4 long. The are palmately divided into 5 or 7 leaflets. The leaflets are narrowly inversely egg-shaped with the attachment at the narrow end, 1 to 2 long, and about ¾ wide. The margins are coarsely toothed around the entire margin, including near the base. The upper surface is green and is covered with short, soft hairs. The lower surface is pale green and is covered with long, soft or stiff hairs. Upper leaves, above the point where the flower stalks begin to appear, are similar but smaller and divided into 3 leaflets.

The inflorescence is a flattened, branched cluster of many flowers at the end of the stem.

The flowers are ½ to 1 wide. The 5 petals are pale yellow. They are inversely heart-shaped, broadest at the tip with two rounded lobes separated by a broad notch, and tapering to a narrow, wedge-shaped base. The 5 green sepals are shorter than the petals and alternate with the petals. The 5 bractlets are dark green and about as long as the sepals when the flower is fully open. They alternate with the sepals and are hidden below the petals when the flower is viewed from above. There are 20 to 30 yellow stamens with brown and yellow anthers. There is no floral scent.

Similar Species

 
 

Sulphur cinquefoil is the only cinquefoil in Minnesota that has pale yellow flowers.

The erect stature, palmately divided leaves with up to 7 leaflets, flower cluster at the tip of the stem, and pale yellow flowers, taken together, distinguish sulphur cinquefoil from all other cinquefoils in Minnesota.

Tall cinquefoil (Drymocallis arguta) leaves are pinnately divided into 7 to 11 leaflets. The petals are yellowish-white, cream colored, or nearly white, and are rounded at the tip, not notched.

Glossary

Bract

Modified leaf at the base of a flower stalk or flower cluster.

 

Bractlet

A small, often secondary bract within an inflorescence; a bract that is borne on a petiole instead of subtending it.

 

Caudex

A short, thickened, woody, persistent enlargement of the stem, at or below ground level, used for water storage.

 

Glandular hairs

Hairs spread over aerial vegetation that secrete essential oils. The oils act to protect against herbivores and pathogens or, when on a flower part, attract pollinators. The hairs have a sticky or oily feel.

 

Palmately divided

Similar to a hand. Having more than three lobes that radiate from a single point at the base of the leaf.

 

Sepal

An outer floral leaf, usually green but sometimes colored, at the base of a flower.
