Flower identification. According or basing to principal parts (complete & incomplete flower) 2. According to the functional point of view (perfect & imperfect flower)
According or basing to principal parts (complete & incomplete flower)
2. According to the functional point of view (perfect & imperfect flower)
A plant is with imperfect flowers is dioecious, if staminate and pistillate flowers are borne on different individual flower. Monoecious if staminate and pistillate flowers are borne on the same individual flower.
3. Based on the fusion of flower parts (connate, adnate & distinct flower)
A flower that lack petals is called apetalous.A calyx of connate sepals is synsepalous, while the fused portion of a synsepalous calyx is a calyx tube and the separate tips are calyx lobes.If the petals are connate into a ring or tube and fall together as a unit, the corolla may be described as gamepetalous.
Common structure in the androecium cont………If the filaments of all the stamen are connate into a ring, the stamens are monodelphous.In members of several other families stamens are connate in bunches are called polyadelphous, often with several to many stamens each.Stamens with filaments adnate to the petals are epipetalous.Stamens may be fewer than, equal to, twice as many as or more than twice as many as the petals, often considered to be numerous or many. When the stamens are as many as or fewer than the petal they are alternate with the petals and it attached between the petals or opposite if they are directly infront of the petals.
When bases of the perianth parts and stamens are adnate to the ovary wall.
