Abstract
IN a recent paper, F. J. Nutman1 has described the behaviour of the stomata of the coffee plant and directed attention to their remarkable sensitiveness to insolation. Within three minutes of exposure to direct sunlight the stomata begin to close, even though the water supply is abundant. Moreover, the closure is reversible: shading a single leaf on an insolated plant results in opening of the stomata of the shaded leaf. This is quite outside the normal range of stomatal behaviour hitherto described.
