The anthers open rapidly after the stamen filaments straighten. On the lower surface of the anther, there is a small patch of unpigmented epidermis to which the filament is attached.
An anther in the process of dehiscence. The pigmented epidermal cells are almost discernable.
at slightly different stages of opening. are present in the same flower. The partially dehydrated triangular pollen grains have central indentations
Polen is present in in each loculus
A closeup of scabious pollen
A very high-resolution image of an isolated anther reveals the individual epidermal cells and the presence of very small protrusions on the pollen surface. The pollen is about 1 /9 th of a millimetre in size
The anther of the stamen on the right has been shed at its point of connection to the filament. The top of the filament is brown.
The top of the stamen filament in this anther seems compressed or partially lost.
Shed anthers lying on the large petals of the marginal flowers vary considerably in colour and shape and in the amount of pollen they contain.
In this flower, most of the anthers have been shed. The reminign anthr has become discoloured and the filament has distorted and become bent.
Once the anthers are shed, the pistils (carpels) begin to grow.
