Stamens and Styles
Crocus have three pollen bearing anthers.
Crocus kotschyanus kotschyanus: White anthers, white pollen.
Crocus serotinus salzmannii: Yellow anthers, yellow pollen.
Occasionally they are blackish maroon, in this case the pollen is yellow.
The style, which has a sticky surface at the tip to receive pollen, takes many different forms. Some of these are illustrated below.
Crocus serotinus clusii: This has a simple three branched orange style which divides above the anthers.
Crocus cartwrightianus: A white form, which has three bright red style branches, which divide in the throat of the flower and are expanded at the apex. This form has purple filaments (the stalks holding the anthers) and a pubescent (hairy) throat.
Crocus caspius: A yellow three branched style which is characteristically hooked at the tips.
Crocus tournefortii: A much branched orange style, an attractive feature of some species. Note also the yellow filaments holding white anthers.
Crocus banaticus: Many branched style, purple, unique to this species.
