The genus *Myosotis* consists of flowering plants within the borage family, Boraginaceae.

In the Northern Hemisphere, these plants are commonly called forget-me-nots or scorpion grasses. The forget-me-not holds special status as the official flower of Alaska. The scientific name *Myosotis* is derived from an Ancient Greek term meaning "mouse's ear." This name refers to the appearance of the plant's foliage. It is important to distinguish this genus from *Myosotidium*, a related group found in the Chatham Islands. *Myosotis* species are herbaceous plants that can be either annuals or perennials. They often grow in moist habitats, such as wetlands and riverbanks.

The physical structure of *Myosotis* is quite distinct. The flowers are pentamerous and actinomorphic, meaning they have five-part symmetry and are shaped like stars. These flowers are borne on scorpioid cymes, which are flower clusters that curve in a spiral. This curling shape is why some species, like *Myosotis scorpioides*, are called scorpion grass. The flowers are typically flat-faced and have a diameter of one centimeter or less. While blue is the most common color, flowers can also be pink, white, or yellow. At the center, five anthers sit on filaments that are fused to the petals. These anthers are surrounded by small yellow bumps known as fornices.

Reproduction in *Myosotis* involves a clever method for spreading seeds. The seeds are held in small, tulip-shaped pods that grow along the stem. These pods have a unique way of traveling to new locations. When a person or animal brushes against the stem, the pods attach to their clothing. Eventually, the pods fall off and leave the seed behind to germinate in a new place. For those studying the plant, seeds can be collected by placing a sheet of paper under the stems. Shaking the pods onto the paper allows the seeds to be gathered easily. This process ensures the plants can spread throughout their preferred moist environments.

The history of the genus began with the work of Carl Linnaeus. He was the scientist who originally described the genus. The type species for the group is *Myosotis scorpioides*. Taxonomy, the science of naming and classifying organisms, has seen much change for this group. While there have been more than 510 recorded names for *Myosotis*, only 156 species are currently accepted by scientists. The other names are considered either synonyms or hybrids. This shows how much work goes into understanding the exact relationships between different plant species.

*Myosotis* has a widespread but specific distribution across the globe. The genus is largely restricted to western Eurasia, where over 60 confirmed species exist. New Zealand is another major center for the genus, with around 40 endemic species. Endemic means these species are found nowhere else on Earth. Genetic analysis suggests the genus originated in the Northern Hemisphere. It likely reached the Southern Hemisphere through a single dispersal event. While a few species appear in North and South America or Papua New Guinea, many plants seen today are introduced cultivars. These human-introduced species are now common in temperate latitudes.

These plants play a vital role in their local ecosystems. They serve as a food source for the larvae of certain Lepidoptera, which are moths and butterflies. An example of this is the setaceous Hebrew character. In some regions, such as New Zealand, many species are currently considered threatened. Because they prefer moist habitats, they often escape into local wetlands when introduced to new areas. This movement shows how closely the plants are tied to the availability of water and specific soil conditions in their environment.

Beyond biology, the forget-me-not carries heavy symbolic weight in human culture. In 1926, the Grand Lodge Zur Sonne used the flower as a Masonic emblem. During the Nazi era, a similar badge was used by the Winterhilfswerk. This allowed Freemasons to use the flower as a secret sign of membership. Today, the flower is used by many groups to represent remembrance. In the United Kingdom, it is a symbol for the Alzheimer's Society and dementia awareness. In Armenia, a specific flower design commemorates the Armenian genocide. The design uses five petals to represent the five continents where Armenians escaped. In Newfoundland and Labrador, it commemorates those lost in the First World War. In art, the flower has symbolized everlasting love since the Medieval period.
