This species, known locally under the name of ‘‘romero,”’ which other species 
belonging to the Andes also bear, has probably been confused with Marcetia 
guniperina and M. cordigera DC. It differs from the latter by its leaves, 
which are petiolate and broader, and by its decidedly larger flowers, from the 
former also by the distinctly heart-shaped leaves, the five nerves of which 
are clearly visible in the fully developed blade. Moreover, it lacks the super- 
foliary punctations indicated as being characteristic of MW. junzperina and the 
calyx tube is longer than the segments thereof; the petals are very sharp- 
pointed but not long-acuminate, and the stamens stand out the whole length 
of the anthers. These differences are accentuated when the dimensions of the 
various parts are taken into account.
