Distribution and habitat —In southern South America, the species occurs in Argentina (Corrientes, Formosa, Misiones), Brazil (Paraná and Rio Grande do Sul) and Paraguay (Amambay, Caazapá, Canindeyú, Central, Cordillera, Guiará, Itapúa, Ñeembucú, Paraguarí, San Pedro). According to Dematteis & Cabrera (2009), in Paraguay this species is also found in Alto Paraná, Caaguazú, Concepción, Misiones and Presidente Hayes. The species can be possibly found in the Argentinian provinces of Tucumán and Salta ( Marques & Dematteis 2014). It inhabits crop fields, cerrado fields, wetland regions, forest margins and canopy ( Figure 18 ).

Phenology —The species blooms throughout the year.

Notes —This species can be confused with L. amambaia and L. setososquamosa , which also occur in southern South America, but L. remotiflora can be differentiated from both species by its acute leaf apex, eucamptodromous-reticulodromous venation, inner phyllaries with acute apex and the presence of glandular trichomes on the style branches and corolla lobes. See comments under L. amambaia .
