Mussaenda pubescens has perfect (hermaphroditic) flowers and populations with two style-length morphs but only weak differentiation in anther position (stigma-height dimorphism). Mussaenda pubescens is a plant from the coffee family, Rubiaceae that is found in Indonesia. The plant grows wild on hillsides, shrubs, and is often cultivated as an ornamental plant. To the Sumatran Malays, this plant is known as daun putri or nusa indah (though the latter name refers to other species).
