Obs. Had Linnaeus examined the fruit of this genus, or even attended to the figure given of it in the " Hortus Malabaricus" (of which work, it is proper to observe, he had not a copy), it is probable he would have distinguished it from Echites, to which it has so little affinity. As it is, I am happy in having it in my power to commemorate the merits of Dr. Alston, the predecessor of Dr. Hope, by so distinct and splendid a genus. The Alstonia of the Younger Linnaeus, is, according to L'Heritier, a species of Symplocos.
