In many plants, margins of leaves, petals and sepals are wavy in characteristics. This type of wavy margin is termed undulate.
In the family of Orchidaceae also, undulating leaves, petals and sepals are not an uncommon characteristic, but certainly not with the lip. Only a few orchid species have their lip margin undulate. Genus Phaius is an example with a few species possessing undulate lip margin.
