Asimina tetramera
Also called Four-petal Pawpaw
Asimina tetramera, commonly known as the four-petal pawpaw, is a rare species of small tree or perennial shrub endemic to Martin and Palm Beach Counties in the state of Florida. The species is currently listed as endangered under the Endangered Species Act and as endangered by the International Union for Conservation. The four-petal pawpaw is part of the family Annonaceae alongside other Asimina species.
A. tetramera grows to between 1 and 3 meters tall with one or more branches. Mature flowers are maroon with some pink streaks and the fruit is yellow-green. It usually has six petals and four sepals.
Specialist insect species use A. tetramera to rear larvae. Both Zebra swallowtail butterflies and Asimina webworm moths lay eggs on A. tetramera leaves and the emerging larvae then eat leaves and flowers from the growing plant. Herbivory damages the developing shoots, which stimulates growth in the plant and extends the breeding cycle for the insects.
