Infrequent near Port Antonio, Jamaica (919 $). Ascending pro- 

 fusely among bushes at The Ovens, Santiago de Cuba (1122^). 

 Scrub above the beach at Pedernales Point, Isle of Pines (1420 $ ). 

 Abundant and with large densely flowered panicles near San Miguel, 

 Cozumel (1498 $ ), and in the center of the island (1574 $ ). 



These specimens display two groups of forms, one probably rep- 

 resenting the type with its leaves acuminate at both ends, and plant 

 glabrous throughout; the other with the older leaves subcordate at 

 the base, more or less pubescent, and with stems manifestly puberu- 

 lent (919, 1122, 1420).
