Featherfoil (Hottonia inflata)

Featherfoil is a short-lived aquatic herb with an entirely submerged, spongy, densely leafy, hollow stem. The successive segments of the stem become progressively shorter bearing a terminal umbel of racemes. The white flowers are small (5-8 cm) in whorled verticils of 2-10 at the joints. The leaves are sessile, or nearly so, oblong (2-6 cm) and divided into narrowly, linear entire segments.

Known populations occur in vernal pools in southern Maine. The species is believed to be a winter annual, with seeds germinating in the fall and resuming growth in the spring.
