||Erect plant, 1-3 feet tall. Leaves long
oval, obtusely pointed, on distinct stalks, opposite each other
on the stem. Flowers small, greenish-white, in small
clusters. Fruits are long, thin, cylindrical pods, in pairs.
Occasional in open areas, especially in the south field and
along Wildwood Drive and the bikeway.
The leaves look a lot like milkweed leaves, and, like
milkweed leaves, are opposite each other. Milkweeds,
however, have very different flowers and fruits. Spreading
dogbane (A. androsaemifolium) is somewhat similar but has
pink flowers and has not been reported in the Park.
