N ASDEVALLLA HOUTTEANA was discovered by Roezl near Frontino in the 
Western Cordilleras of Antioquia, at an elevation of 8,000 feet, and his dried 
specimens were named by Professor Reichenbach in 1874. Like most of its allies, 
M. Houtteane is a variable species, and local varieties subsequently found by Roezl and 
other collectors, received from Reichenbach the specific names of Benedicti and paittacina.
