The Convolvulacaeae family is known as the Bindweed or Morning Glory family and is found primarily in the tropics and subtropics, but has become cosmopolitan. The family takes its name after the genus Ipomoea (Figure 1), but another 14 genera are also found in the state. In Florida, the family is home to 40 native and 27 non-native species (including varieties and subspecies). The state-listed endangered Bonamia grandiflora or Florida lady’s nightcap (Figure 2) is a member of this family.
