The percentages given by lots XX and XXX are very nearly equal. It may be inferred from Table II that fertilization under bags is an excellent method of securing selected seeds, but in order to obtain a good yield of seeds the capsules should be uncovered as soon as the fertilization is completed. At this time, the plant should be watched with the greatest care in order to prevent the formation and the pollination of new flower«. 1664—2.
