Hamamelidae

Hamamelidae es el subclase de plantas herbáceas o leñosas de la clase Angiospermae. Las hojas pueden ser simples o, más raramente, pinnadas o palmadas. Las flores suelen ser pequeñas e inconspicuas y anemófilas o secundaria secundariamente entomófilas. Generalmente carecen de perianto o, bien, éste es apétalo.
