This family exhibits great diversity in architecture. Some plants show ordinary shoots while others lack a shoot and among these the one-leaf plants possess one enlarged cotyledon as sole photosynthetic organ. Floral forms also vary greatly even within genera perhaps in response to pollinator adaptations. We study the genetic and developmental mechanisms underlying this variation in an evolutionary framework.
