Calyptranthes thomasiana

Thomas' Lidflower

Origin:  Calyptranthes thomasiana in the Myrtaceae family is a rare species of plant. It can be found on three islands in the Caribbean. Less than 250 individual plants are among the islands of St. John in the United States Virgin Islands, Vieques in Puerto Rico and Virgin Gorda in the British Virgin Islands. It was first described in 1855 in the wild on Saint Thomas, United States Virgin Islands but has since been eradicated and only grows there in cultivation.
