The principal results obtained were as follows. 1. There are varietal differences in the developing type of the plant, in the spine number on the bract and in the number of bract. 2. The flowers bloom out in order from the top of a main stem to its lower branches. 3. The flowers begin to bloom at 4 a. m., and at 6 a. m. the stigmas are already covered with pollens. 4. Generally, yellow flowered varieties contain larger amounts of oil than those in red flowered varieties. 5. The oil content in the seed correlated decidedly to the hull percentage of it (r =ca. 0.8) 6. Fertilization is remarkably restricted by rain fall. The fact may be related with protandry. 7. For the growth of the plant, autumn sowing is better than spring one, and direct planting is better than transplanting.
