What does althaea mean?
Althaea is a small genus of herbaceous flowering plants belonging to the mallow family, Malvaceae, found naturally in Europe, western Asia, and North Africa. Its most famous member is Althaea officinalis, the marshmallow plant, a downy-stemmed perennial with pale pink flowers that grows in damp, salty places such as marshes and coastal meadows. For centuries the plant's mucilage-rich root was valued in traditional medicine as a soothing treatment for coughs, sore throats, and digestive complaints, and it gave its name to the original marshmallow confection, a paste of root extract sweetened with honey — though today's marshmallows contain no trace of the plant. The name also belongs to Althaea, queen of Calydon in Greek mythology, whose burning of a magical log sealed her son Meleager's fate. In modern usage the word appears chiefly in botany, herbalism, and classical reference works.
A genus of herbaceous plants in the mallow family (Malvaceae), including the marshmallow plant (Althaea officinalis).
"Botanists reclassified several species out of the genus Althaea as molecular studies reshaped the mallow family tree."
When used as a formal taxonomic name, the word is capitalized and italicized (Althaea); in general prose it is lowercase.
In Greek mythology, Althaea is the queen of Calydon, wife of Oeneus and mother of Meleager, whose life was tied to a burning brand she ultimately destroyed.
"The tragedians made much of Althaea's terrible choice between her brother and her son."
This sense appears only in classical and literary contexts.
As a taxonomic genus name, Althaea is treated as singular and is not pluralized; the plural form arises only when referring informally to multiple individual plants.
"The border was planted with althaeas alongside other moisture-loving mallows."
The marshmallows you toast over a campfire share nothing with the original marshmallow — a medicinal sweet once made from the root of the althaea plant.

Etymology of althaea
The name althaea comes from the ancient Greek ἀλαθέα (althaia), the word the Greeks used for the marshmallow plant, and it was adopted into Latin botanical nomenclature before entering scientific English. The Greek name is traditionally associated with the verb ἀλθεῖν (althein), meaning 'to heal,' a fitting origin for a plant long prized for its medicinal properties. The same Greek root produced the mythological heroine Althaea, mother of Meleager, and the closely related spelling 'althea' remains a widely accepted variant in both botanical and garden usage.
How althaea is actually used
Althaea is primarily encountered in botanical, horticultural, and historical-medical writing rather than everyday conversation. In casual gardening contexts the variant spelling 'althea' is at least as common, and the two are frequently used interchangeably for the genus. The mythological sense appears almost exclusively in classical literature and retellings of the Meleager legend.
Easily confused with althaea
Althaea is the botanical genus containing the marshmallow plant, while 'althea' is both a common alternate spelling of that genus name and the popular name for the unrelated Rose of Sharon shrub (Hibiscus syriacus).
Marshmallow refers either to the plant Althaea officinalis itself or to the modern puffy confection, which no longer contains any part of the althaea plant.
