Detailed Information

Flower: Flower shape: irregular Cluster type: raceme Cluster type: spike

[photo of flowers] Purple/pink to nearly white flowers are spaced out on a spike-like raceme 1 to 3 inches long at the top of the stem. Flowers are ¼ to 3/8 inch across with 2 wing-like sepals flanking 2 petals rolled into a column in the center, with a fringed crest.

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

[photo of leaves] Leaves are to 1 inch long and 1/6 inch wide, toothless, hairless, usually wider at the tip end, tapering to a narrow or blunt point at the tip with no leaf stem. There are usually multiple, unbranched stems emerging from a sturdy taproot. The stems may be erect but often fan out from the center of the clump, each stem leaning over or sprawling along the ground with the tip rising up (decumbent).

Fruit:

This species also has small underground flowers on short underground stems that produce seed asexually (cleistogamous), though a few upper flowers can do this as well.

Notes:

This milkwort species is generally found from the Metro and SE border counties to Houston County, though scattered populations have been located as far north as Beltrami and St. Louis counties. When open, the flowers are near minatures of the more showy and larger Fringed Milkwort (P. paucifolia) though flower components are proportionally different and the tip fringe is lighter, more open and splayed out.
