Each 1 inch (2.5 cm) wide flower is actually a cluster of 3 bilaterally symmetric flowers. The flowers emerge from the leaf axils and have deeply scalloped petals. The flowers are followed by 5-ribbed fruit with a deeply convex stem end and 0 (common) to 4 teeth on each rib. The leaves are green, hairy, oval-shaped, and paired opposite each other but unequal in size. The leaves near the base of the plant are the largest. The stems are plump, trailing, and often reddish in color. Both the leaves and stems are hairy and sticky.

3/21/17. There are two very different sized flowers on different specimens of Allionia incarnata (Trailing Windmills). They are the same genus and species but two different varieties. Flower cluster size is a good indicator and a good field ID characteristic for the two varieties. The bigger flowered one is var villosa, and the smaller flowered one is var incarnata.
