Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar ; they may also ...
P. lindeniana is the largest of the free-standing trees in its subgenus, growing to 20 metres (66 ft) tall, and with a circumference up to 1.25 m (4 ft) at the base. [ 1 ] The tree is branched and leafy above a bare, brown-barked trunk, and the large ( 10 to 90 centimetres (4 to 35 + 1 ⁄ 2 in) long) simple leaves form a moderately dense canopy.
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in Salix). It contains many, usually unisexual flowers, arranged closely along a central stem that is often drooping.
Unpollinated flower Early development of seed body after hand pollination, seen as a swelling at the base of the flower. The plant points the whole stalk downwards once all the flowers have been exhausted. Flowers drop off if not pollinated, and stalk dies if it contains no pollinated flowers.
Hummingbird Phaethornis longirostris on an Etlingera inflorescence. Ornithophily or bird pollination is the pollination of flowering plants by birds.This sometimes (but not always) coevolutionary association is derived from insect pollination (entomophily) and is particularly well developed in some parts of the world, especially in the tropics, Southern Africa, and on some island chains.

Insect-pollinated flowers use a combination of cues to advertise themselves to insects. Further information: flower and entomophily Insect-pollinated flowers use bright colours, patterns, rewards of nectar and pollen , and scent to attract pollinators such as bees . [ 1 ]
Examples of pollinator-mediated selected traits could be those involving the size, shape, color and odor of flowers, corolla tube length and width, size of inflorescence, floral rewards and amount, nectar guides, and phenology. Since these types of traits are likely to be involved in attracting pollinators, they may very well be the result of ...
