Name: Starfruit (Damasonium alisma)
Status: Once found in several counties of England, the now critically endangered starfruit is limited to just a few sites in Buckinghamshire, Berkshire and Surrey. It is illegal to pick or intentionally damage the plant.
Threats: The aquatic plant, with white flowers and star-shaped fruits, prefers the edges of muddy ponds, turned up by cattle in the pastures looking for a drink. But development has made this habitat scarce.
