**Water pollination is commonly seen in genera of some monocots.**
Water pollination, also known as hydrophily, is a method of pollination in which the transfer of pollen grains occurs through water. This type of pollination is mostly observed in aquatic or semi-aquatic plants. It is a relatively less common method of pollination compared to wind or insect pollination. In water pollination, the pollen grains are released into the water, and then they are carried by water currents to reach the female reproductive structures (such as ovules or stigma) of the same or different plants.
**Explanation:**
Water pollination is not observed in all plants, but it is commonly seen in some monocots. Monocots are a group of flowering plants that possess certain characteristics, including having a single cotyledon (embryonic leaf) in their seeds, parallel-veined leaves, and scattered vascular bundles in their stems.
Some common examples of monocots that exhibit water pollination are:
1. **Vallisneria**: Vallisneria is a submerged aquatic plant commonly known as tape grass or eelgrass. It is a dioecious plant, meaning it has separate male and female flowers on different plants. The male flowers release long, coiled stalks called peduncles that carry the pollen grains to the surface of the water, where they float and are carried by water currents to the female flowers.
2. **Hydrilla**: Hydrilla is another submerged aquatic plant that exhibits water pollination. It is an invasive species and forms dense mats in freshwater bodies. The male flowers of Hydrilla release the pollen grains into the water, and they are transported to the female flowers through water currents.
3. **Zostera**: Zostera, commonly known as eelgrass, is a marine plant that grows in coastal areas. It has both male and female flowers on the same plant. The male flowers produce pollen grains that are released into the water, and they are carried to the female flowers by water movement.
These examples demonstrate how water pollination is observed in some monocots. However, it is important to note that not all monocots exhibit water pollination. Some monocots, like grasses, rely on wind pollination, while others, like orchids, are predominantly pollinated by insects. Thus, the statement that water pollination is commonly seen in genera of some monocots is correct.

Hydrophily is seen in 30 genera, of monocotyledons.
