The seed thus produced waH allowed to germinate on bare sand ; and the seedlings were planted in the usual manner on tho opposite sides ·of Hix pots. All the remaining seeds, whether or not in a state of germination, were sown thickly in Pot VII.; the throe tallest plants on each side of this latter pot being alone measured. As I was in a hurry to learn the result, some of these seeds were sown late in the autumn, but the plants grew so irregularly during the winter, that one crossed plant was 28~ inches, and two others only 4, or less than 4 inches in height, as may be seen in Table XXI. Under such circumstances, as I have observed in many other cases, the result is not in the least trustworthy; nevertheless I feel bound to give the measurements. TABLE XXI.
