- Observation Dalechampia has protogynic bisexual pseudanthia with unisexual perianthed flowers.
- Observation Euphorbia has protogynic bisexual pseudanthia with achlamydeous flowers.
- Observation Pera has unisexual pseudanthia with vestigial calyces in male flowers and achlamydeous female flowers.
- Observation Joannesia flowers retain all whorls without reduction.
- Observation Floral primordia initiate almost simultaneously with the involucre.
- Observation Early inflorescences follow the same branching pattern across the studied genera.
- Association Early female flower development in the terminal position affects branch number and elongation.
- Mechanism The authors propose that pseudanthia evolved through floral whorl reduction and reorganization of flowers and branches.
- Mechanism Protogynic development reduces branching and axis elongation in pseudanthia.
