The characters relied upon in considerable part to separate M . im- 

 plexus from M. corallinus are leaf characters, but the descriptions 

 of the leaves of M . implexus, as given by Dr. Greene, leave one in some 

 perplexity. In the publication of M. implexus, its characters are 

 briefly indicated from the original description (as M. Tilingi}, and 

 it is further noted that "No other member of the group makes any 

 approach to it, either in this character or in that of the exceedingly 

 thin membranaceous texture of the leaves." A year later, in a note 

 subjoined to the description of M. corallinus, the leaves of M. implexus 

 are asserted to be "of unusual thickness and fleshiness of texture."
