corolla tube

TThe corolla tube is the tubular base of a flower, formed when the petals are fused together.

This structure guides pollinators to nectar and reproductive parts, playing a key role in pollination.

Its length and shape determine which pollinators can reach the nectar, thereby influencing which species can access it.

The long corolla tube of California Fuchsia (Epilobium canum) is especially adapted to hummingbirds, whose beaks and hovering ability make them ideal pollinators.

This floral structure is a crucial component of the plant’s pollination strategy, attracting specific visitors and thereby enhancing reproductive success.
