gamopetalous การใช้

The corolla is fused ( gamopetalous ), and there are two stamens for every petal.
When petals are fused into a tube or ring that falls away as a single unit, they are sympetalous ( also called "'gamopetalous "').
If the petals are free from one another in the corolla, the plant is " polypetalous " or " choripetalous "; while if the petals are at least partially fused together, it is " gamopetalous " or " sympetalous ".
Thus if the petals are free from one another in the corolla, the plant is " polypetalous " or " choripetalous "; while if the petals are at least partially fused together, it is " gamopetalous " or " sympetalous ".
Prior to the phylogenic classifications of August Eichler and his successors this group corresponds to the Gamopetalae of Bentham and Hooker In Eichler's " Bluthendiagramme ", Sympetalae, also classified as Metachlamydeae, was listed as a subclass of the class Karl Prantl also listed Sympetalae as a division of the class Dicotyledoneae in their system, " Die Naturlichen Pflanzenfamilien ", with Sympetalae being composed of gamopetalous families Alfred Rendle similarly Sympetalae originated from dicots, and then divided Sympetalae into Pentacyclicae and Tetracyclicae in accordance with the number of flower parts in each group.
