Vestigial stamen nectaries In the Lecythidaceae, the inner-most appendages at the apex of a fully-coiled, zygomorphic-flowered, neotropical Lecythidaceae that produce nectar which accumulates in the nectar chamber. Nectar-producing vestigial stamens and nectar chambers are only found in species of and . Fully coiled refers to species that have more than one inward coil, i.e., species with two or more coils.
