Pollenizer
（重定向自Pollinizer）
A pollenizer or polleniser, sometimes pollinizer or polliniser (see spelling differences) is a plant that provides pollen.
The word pollinator is often used when pollenizer is more precise. A pollinator is the biotic agent that moves the pollen, such as bees, moths, bats, and birds. Bees are thus often referred to as 'pollinating insects'.
