Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. [1] Almost all gymnosperms are anemophilous, as are many plants in the order Poales , including grasses , sedges , and rushes . [ 1 ]
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. [1] Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves.
Baltimore Checkerspot (Euphydryas phaeton) nectaring at daisy (Argyranthemum)Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.
Hygrophila auriculata (Sanskrit: gokaṇṭa, Bangla (বাংলা নাম): kulekhara (কুলেখাড়া) [2] kokilākṣa) [3] [4] is a herbaceous, medicinal plant in the acanthus family that grows in marshy places and is native to tropical Asia and Africa.

The most widespread form of self-incompatibility in monocots is gametophytic, [6] meaning compatibility is determined by the genotype of the pollen grain. There are two described mechanisms of gametophytic self-incompatibility that have been shown to occur in four families of dicots (RNase and S-glycoprotein) but none have been found in monocots.
A rufous hummingbird (Selasphorus rufus) is attracted to brightly colored flowers and assists the pollination of the plant.Zoophily, or zoogamy, is a form of pollination whereby pollen is transferred by animals, usually by invertebrates but in some cases vertebrates, [1] particularly birds and bats, but also by other animals.
