Similarly in the Leguminosae a primitive type is seen, with many ovules in each carpel in the Pea or Bean. But Copaifera contains but two ovules, of which one only ripens into an unusually large seed (Fig. 238, p. 318). Again, in the Rosaceae, in Spiraea or Cydonia each carpel is many- ovuled ; but in the Potentilleae, Rubeae and Roseae each has only one. The loss of number is, however, made up by the greater number of carpels. In the Pruneae, on the other hand, the single carpel contains two ovules, of which usually only one matures ; but it grows into a large kernel. The.
