"On the island of Lewchew, (says Mr. M'Leod,) is found a remarkable production, about the size of a cherry-tree, bearing flowers, which, alternately on the same day, assume the tint of the rose or lily, as they are exposed to sunshine or the shade. The bark of this tree is of a dark green, and the flowers bear a resemblance to our common roses. Some of our party, whose powers of vision were strong, (assisted by a vigorous imagination,) fancied that, by attentive watching, the change of hue, from white to red, under the influence of the solar ray, was actually perceptible to the eye: that, however, they altered their colour in the course of a few hours, was very obvious."
