The Construction of Flowers under the Concept of Leaf-Class

1. The floral constructions are considered under the concept of leaf-class.2. In seed plants, there are, at least, two different patterns of floral construction. The one is SF-combination and the other, G-leaf-class.3. The former is made up of two groups, the outer one is composed of 2-F (sepal and outer stamen) and 2-S (two petals). While the inner one, with 2-F (inner stamen and fertile carpel) and 2-S (two sterile carpels).4. In the flower of G-leaf-class, floral leaves are of all G, arranged in pentacyclic manner with alternation of one radius with three member of sepal-outer stamen-carpel and the other, with petal and inner stamen.5. Most types of different flower are in species-specific pattern but can be interpreted as the derivatives modified through several different courses from the above mentioned fundamental architectures.
