C. azurea is cited for Brazil, C. charruana is added to Argentinian flora, C. luteola has its taxonomic delimitation established, and its occurrence is extended up to the northern Uruguay. The geographic distribution of C. riograndensis is reestablished, in view of three collections mentioned in the protologue are identified as belonging at others species. All species studied are described, illustrated through of photos, being presented data about geographic distribution, ecology and conservation. |
