Type locality: Antigua, West Indies. Distribution: Southern Bahamas, Porto Rico, Virgin Islands, St. Christopher, Antigua, Montserrat, and Dominica. Urban, who has followed us in restoring Miller's old specific name in tort its, although using it under Melocactus, has applied the name to the Hispaniolan plant while, as a matter of fact, Miller's plant came from Antigua and represents a very different species. The plant is abundant along and near the coast in southwestern Porto Rico and grows also on the Porto Rican Islands Culebraj Vieques, Mona, and Desecheo; a headland near Cabo Rojo, Punta Melones, has taken its name from this cactus. On the islands Mona and Desecheo in the Mona Passage a race with elongated slender spines exists; and through the Virgin Islands, east to Anegada, the species shows much variability in its armament. It grows on several islands in the southern part of the Bahamas, north to Acklin's Island and Long Island, called Turk's cap or Turk's head here as in the Lesser Antilles; the Turk's Islands have taken their name from this plant which appears on their postage stamps.
