• Background and aims Unifoliate species of Gesneriaceae are unique, as they bear only one leaf throughout their life history. The development of this leaf (termed a macrocotyledon) derived from one of two cotyledons is intriguing. The other cotyledon does not develop further and is termed a microco...
