Haworthia lockwoodii is a species of succulent plant in the genus Haworthia.[1] Native to the Cape Province of South Africa, it was named for a local magistrate.[2]
Among Haworthia species, H. lockwoodii is unusual in appearance during the dormant phase that it enters in times of drought; the external leaves dry out more or less, and lose their turgor. The wilted leaves often cover the plant entirely, which then appears to be almost dead.[3] During the wet season, this leaf cover absorbs water rapidly, becoming turgid and pale green. The shape and colour of the turgid leaves show that the species is a window plant: its leaf tips have panels that are practically colourless and transparent, admitting light to the chloroplasts deep inside.[4]
