Family, Milkweed. Color, greenish white. Flower, already described (p. 10). Leaves, simple, thread-like, whorled, 3 to 6 together, turned-back margins, 2 or 3 inches long.

This is the most ethereal and exquisite of the milkweeds. I first saw it on the top of Federal Hill, Pompton, New Jersey. It is more common southward. A small umbel of delicate flowers terminates a stem, generally, unbranched. The needle-like leaves give it a delicate appearance. Open, rocky woods, and westward in the prairies.
