Description:Species Description - An attractive, low, narrow-leaved, bulbous plant, with rose-red flowers, luxuriant in Porto Rico gardens, and occasionally escaped from cultivation. It is native in Cuba, and naturalized in Bermuda and the Bahamas, in gardens commonly planted as a border along paths.
Atamosco is the aboriginal North American name for the type species of the genus, Amaryllis Atamasco Linnaeus (Atamosco Atamasco Greene), taken up by the French botanist Adanson in 1763. There are about 35 species, natives of tropical and warm-temperate America. They have coated bulbs, long, narrow leaves, and handsome flowers, borne solitary on a slender scape, subtended by a spathe. The flower is funnelform, white, red, pink, purplish or yellow, with 6, nearly equal lobes; the 6 stamens, borne on the throat of the corolla, are nearly alike; the 3-celled ovary contains many ovules; the slender style is topped by 3 stigmas, in some species nearly united. The fruit is a 3-valved capsule, the many, blackish seeds usually flattened. Atamosco rosea (rose-colored flowers) has a nearly globular, short-necked bulb about 2 centimeters in diameter. Its smooth leaves are about 20 centimeters long, or shorter, and from 2 to 5.5 millimeters wide. The leafless, upright scape is slender, and often somewhat longer than the leaves, the stalk of the flower longer than the spathe; the flower is about 3 centimeters long, with a short tube, its lobes obovate, the stamens short, but the style nearly as long as the corolla. The 3-lobed capsule is about 6 millimeters high.
Two other species of Atamosco are grown for ornament in Porto Rioo, and occasionally escaped, or persistent after cultivation.
