In a former memoir published in these Transactions (30) the floral development of the “Cannon-Ball” tree, Couroupita guianensis, Aubl., was described. The most striking floral feature of this remarkable Myrtaceous genus is the androecium, the form, proportions, and position of whose parts produce a curious zygomorphy with cellular gigantism. The Lecythidean andrœcium, and the torus which bears it, were considered of systematic importance and of physiological interest, and deserving of special study with reference to the Myrtaceæ as a whole.
