Detailed Information

Flower: Flower shape: 4-petals Cluster type: panicle

[photo of flowers] Flowers are in many small clusters arising from leaf axils and at the end of branching stems. Flowers are white, about 1/16 inch across on short stalks, have 4 petals (rarely 3 or 5) pointed at the tip, and as many creamy colored stamens as there are petals.

Leaves and stem: Leaf attachment: whorl Leaf type: simple

[photo of leaves] Leaves are mostly whorled in groups of 6, though whorled in 4s on branching stems. Leaves are slender, 1/3 to ¾ inch long with blunt or sharply pointed tips; those in a whorl are uniform in size and spacing. Leaves are slightly rough around the edges. Stems are slender and mostly smooth, or slightly rough along the angles. Plants grow erect or more often sprawling.

Fruit: Fruit type: capsule/pod

[photo of fruit] Fruit is a pair of tiny, smooth round pods, each containing a seed.

Notes:

There are several species of bedstraw, all with small white 4-petaled flowers, some with leaves whorled in 4s, or whorled in 6s. Shining Bedstraw is distinguished from other Galium species by its airy clusters of many tiny flowers, leaves whorled mostly in 6s, and overall delicate appearance. Other 4-petaled bedstraws have flowers 1/8 inch or larger, and typically larger leaves. The woods at Wild River State Park are loaded with this stuff.

We found this along the upper banks of the St. Croix River in William O'Brien State Park on July 3, 2015. Along the river walk path. I have never seen this species before. Your Galium pages made it simple to figure it out to species. Thanks. JH
