Nectar A sugar solution of varied composition produced by nectaries within flowers to attract pollinators or by extrafloral nectaries to attract insects that protect the plant from predation. Nectar in the diurnal flowers of a species of Sapotaceae. Photo by C. A. Gracie.
Nectar chamber A chamber at the apex of the coils of zygomorphic-flowered species or at the base of the staminal tube of most Old World species and in some actinomorphic-flowered genera in the New World, e.g., for example of species of . The nectar that accumulates in the nectar chambers serves as the reward that attracts pollinators to the flowers. The androecium of a zygomorphic-flowered Lecythidaceae. Photo by C. A. Gracie.
Nectar guide Markings on a flower that apparently serve to guide pollinators to the nectar. Some are visible to humans, but others are apparent to humans only through ultraviolet photography. Same as honey guide, a term not recommended because bees, not plants, produce honey. Nectar guides of a Bignoniaceae. Photo by S. A. Mori.
