This species is apparently near M. polycephala Urb. of Haiti, which 
however is described as having the leaves tending to elliptic-oblong, 
obtuse or obtusish at base, and 4-5-nerved, while they are here 
rhombic-ovate acute at base and 3-nerved. There are other minor 
differences and it seems very unlikely that the two plants, growing as 
they do upon different islands, are conspecific.
