0 the part of a flower at the top of a stamen (= small thin male part) that contains pollen -- støvknap
This floral structure may act as a developmental constraint and generate positive anther- corolla correlations.
In order to collect pollen, adults scrape anthers with the proboscis and gather the grains.
Corolla-tube length (a), anther height (b), stigma height (c), corolla-lobe length (d), stigma-lobe length (e), and anther length (f) were measured.
They almost always contacted the stigma and anthers, and were classified as pollinators.
The pollen sacs are confused with anthers and the term ' petiole ' is used for flower stalk which should be ' pedicel'.
Flowers were emasculated by removing the anthers before anthesis in the early evening.
The stigma extends beyond the anthers by a couple of millimetres allowing both hummingbird groups to deposit pollen.
The stamens have a rigid filament and a length that places the anthers beyond the tube of the corolla precisely under its upper lip.
