It is probably named after Timothy Hanson, an American farmer and agriculturalist said to have introduced it from New England to the southern states in the early 18th century. It is more efficient to produce vast amounts of pollen than than enormous petals or scents. Call us on In fact, the bees drop pollen packets that are attached to their backs and properly aligned for them to be placed on the stigma of the next orchid they come across. Pollen grains are produced in large numbers by the anthers, whereas stamens protrude out of the flowers and are generally long and erect. In this case, the interdependence between species is shown to be tenuous at best. Necessary cookies are absolutely essential for the website to function properly. Photo Erich G.

On certain flowers these guides are visible to human eyes. Any one of those only has a miniscule chance of landing on the stigma of one of is own kind, so while the pollen may be carried incredible distances, the majority of the grains tend to land within just a few metres of the plant. To create a new plant, genetic information is transmitted through seeds. It is most common in our temperate deciduous and in boreal forests but extremely uncommon in tropical rain forests. Another adaptation to improve their chances of successful fertilisation is in the structures of the flowers themselves. However, a loss of meadow habitats is the biggest threat to this species.
