M. diptera, Britt.
A second species called the snowdrop tree skirts the swamps along the South Atlantic and Gulf coast and fol lows the Mississippi bayous to southern Arkansas. It is smaller in stature than the silver bell tree, but has larger leaves and more showy flowers. The botanical names record the chief specific difference between the two species: this one has but two wings on its seed-cases, while the other has four. This species is hardy no farther north than
Philadelphia. The flowers have their bells cleft almost to the base, whereas the bell of the other species is merely notched at the top.
