Marmoraceae

Marmoraceae is a monotypic genus of flowering plants in the family Gentianaceae. It contains a single species, Marmoraceae fluminensis, which is native to South America, specifically Brazil. This plant is characterized by its herbaceous nature and is typically found in moist, shaded habitats. The genus name "Marmoraceae" is derived from the Latin word "marmor," meaning marble, likely referring to the marbled or patterned appearance of its leaves, though this feature is not always pronounced.

Marmoraceae fluminensis is a relatively small plant, often growing to a height of no more than 20 centimeters. Its leaves are usually ovate to lanceolate and arranged in a basal rosette. The flowers are typically small and star-shaped, with five petals, and can vary in color, often appearing in shades of white, pale blue, or pink. The plant reproduces through seeds and can also spread vegetatively. Its habitat is generally restricted to the Atlantic Forest biome, where it thrives in the understory of humid forests. Due to its specific ecological requirements and limited distribution, Marmoraceae fluminensis is considered a species of conservation concern in some regions. Further research into its reproductive biology and population dynamics is ongoing to better understand its conservation needs.
