A closeup of a floret in the process of opening reveals the anther filaments at various stages of unbending.
In this opened up flower, the green phyllaries have long stalks. Each floret has a collar of connected processes that give rise to the pappus
The internal configuration of six microdissected florets in which the petals have been totally or partially removed. Note that soon after dissection some anthers have begun to open, possibly as a result of desiccation. The anthers have begun become pigmented before the loculi adopt their final configuration.
A microdissected unopened floret cur near the top of the anthers shows the close packing of these structures
2 microdissected unopened florets show that the pollen is in a swollen or hydrated state at this stage in development.
A dissected floret in which the pappus and green phyllaries have been removed. It seems possible that the brown pappus bristles act to constrain circumferential grow.
In this dissected floret the developing pappus has been retained but partially opened.
3 isolated florets at different stages of opening
A closeup of a partially dissected unopened floret in which the upper parts of the developing petals have been removed to reveal the folded stamen filaments on the outer surface of the anthers.
