👉 Alvimiantha is a genus in the family Alvimiatidae, which contains several species of flowering plants native to South America. These plants are known for their large flowers and colorful petals that come in shades of pink, white, or purple. The genus was named by French botanist Jean-Baptiste Lamarck in 1804, but the specific name "Alvimiantha" is associated with the genus Alvimia, which is a closely related species.
