Abstract
A new subspecies ofConsolea millspaughii is described from the eastern bluff of Cayman Brac and northern coastal terrace of Little Cayman (Cayman Islands, British West Indies). This taxon has been mistakenly identified asConsolea spinosissima since its first collection in 1938. However, the smooth surface of its stem segments, not being demarcated by a network of depressed lines, its pitted areoles, and the fairly reduced pedicellate area of the pericarpel set is apart from this Jamaican endemic. Because the novelty here described brings to three the number ofConsolea taxa that are characterized by very closely set, pitted areoles, an informal “C. millspaughii species-group” is recognized. This assemblage of Western Caribbean opuntioids includesConsolea corallicola, C. millspaughii subsp.millspaughii, andC. millspaughii subsp.caymannnsis. The new subspecies is described, illustrated, and compared withC. spinosissima and with kindred taxa within the species-group. A key to all species and subspecies ofConsolea is provided.
