showing signs of division. 
Text-fig. 9. At level 2. The main bundle A has divided into a and # , and a shows signs of 
division. 
Text-fig. 10. At level 3. a has now divided into a 1 and a 2 (dotted line), which are bundles of 
equal size, supplying the anterior and posterior sides of the part of the ovule next to the sporophyll. 
Text-fig. ii. At level 4. The bundles a 1 and a 2 are entering the ovule. The branch b has
