I found this plant on the skirts of the extensive forests of the 

 Organ Mountains ; the branchlets are green, smooth, round, 

 marked with numerous minute whitish specks, woody but fistu-

 tomentose petioles of a line in length ; the upper ones are 3 inches 

 long, 7 lines broad, on a petiole of 1^ line ; and the terminal one
