TROPICAL AMERICAN EUPATORIEAE 13 
472 (1905), but the (still immature) involucral scales are no less 
than 8-9 mm. long and only 1.4-1.5 mm. wide, nearly smooth, and 
narrowed to a rounded or obtuse tip, while in M. brachyphylla the 
scales even at full anthesis are only 5.5-6 mm. long, fully 2 mm. wide, 
perceptibly villosulous, and terminate in a triangular acutish tip— 
differences which seem unlikely to occur within the limits of a single 
species.
