Naudin distinguished the Marcetia collected in Merida by Funck and 
Schlim (no. 1200) under the name of MW. andicola, but this was later reduced 
by Cogniaux to the rank of a variety of M. cordigera. We take Naudin’s 
plant to be the same as the one described here, and believe that it cannot be 
assimilated with M. cordigera on account of having petiolate leaves, nor with 
M. juniperina, primarily because of these being 5-nerved. Certainly it 
shows a close relationship with the latter, but still it differs from it sufficiently 
to justify its being considered as a distinct species. 
After writing the above, I had the opportunity, thanks to the kindness of 
Professor Lecomte, of the Museum of Natural History in Paris, of comparing 
the materials collected by Dr. Jahn with the type of Marcetia andicola 
Naudin. Thus I was able to convince myself that this and Jahn’s collections 
are identical, and moreover, that the species of Naudin should not be mistaken 
for Marcetia cordigera DC. nor even be considered as a variety of it. This 
opinion is further confirmed by a careful comparison with the original 
descriptions and analytical sketches of Naudin, of which latter Prof. Lecomte 
also had the kindness to send me tracings.

Miconia rufostellulata belongs in the Section Ewmiconia, in the series 
Paniculares, and should be placed near M. brevipes Benth., from which it 
differs in the indument, the coloring of the leaves, the larger petals, and other 
characters.
