Notas y observaciones

Specimens have usually been determined in the past as Fleischmannia prasiifolia with which it shares many characteristics such as ascending branches, short peduncles in the inflorescence, purple color of the corollas and achenes with somewhat paler ribs. The new species differs by the smaller more densely pubescent leaves and smaller clusters of heads, and it occurs far to the east of the distribution of F. prasiifolia and at generally lower elevations. The presence of minute glandular dots on the abaxial leaf surfaces would also seem to be a distinction, but minute stipitate glands occur in Fleischmannia prasiifolia var. glandulifera as noted in the Bolivian treatment.
