Rio Grande do Sul : Bom Jesus, Santo Inácio, 11 March 2005 , G. Hatschbach 79077 (CTES). Distribution and habitat —The species is restricted to the south of Brazil and is known in Argentina through a unique collection from the province of Misiones. Lepidaploa pseudomuricata inhabits fields and wetland regions but is commonly found on margins or under canopy of the Atlantic Rainforest ( Figure 14 ). Phenology —The species blooms between April and December. Notes —The species can be easily differentiated from the other species that occur in southern South America by glandular trichomes on its anthers, prominently ribbed branches, erect subshrubby or shrubby habit and narrow basal stylar node.
