Labellate

Labellate refers to a characteristic found in certain plant structures, particularly within the family Orchidaceae. It describes a modified part of the labellum, which is the petal that is typically the most prominent and often the most highly modified in an orchid flower. The term "labellate" implies that this modified part of the labellum is shaped like a small lip or a small, tongue-like structure.

This labellate feature can manifest in various ways. It might be a small, projecting lobe, a fringe, or a series of small appendages located on the main body of the labellum. The precise form and appearance of the labellate structure can vary greatly between different orchid species, contributing to the diversity of orchid flower morphology. These structures often play a role in attracting specific pollinators, guiding them towards the reproductive parts of the flower, or providing a landing platform. Their presence and form are important diagnostic features used in the identification and classification of orchids. The term can also be applied more generally to other botanical structures that exhibit a similar small, lip-like shape.
