Ecuador, 2750 m. altitude, 21 January, 1856; W. Jameson, no. 162 
(type, in Gray Herb.). From the original M. flaverioides HBK. of 
Venezuela, as well as from the recent M. Jelskii Hieron. of Peru, the 
present species differs in its many-flowered heads, the disk-flowers 
being about 25, while in M. flaverioides they are said to be 5-10 and 
in M. Jelskii they are 6-7. Furthermore, the form of the leaf in the 
Ecuadorean plant is very different from either of the other species, the 
blade being more nearly deltoid with a truncate base somewhat sharply 
distinguishable from the cuneately winged petiole.
