Argyreia convolvuloides is homotypic synonym of Blinkworthia convolvuloides.
Invasive in an Eucalyptus plantation.
Quite new for Brazil and even continental neotropics!
This paleotropical species is known from Africa, Asia and Australia. In the Americas, this species was only known from a naturalized population on Puerto Rico (where known since at least 1887, see GBIF and Inaturalist).
Apart from records from Puerto Rico, the GBIF mentionned three records of this species from the Americas. One is of a specimen cultivated in California (here). Another record from Goias (here) seems to be an error for Ipomoea aprica (via its synonym I. angustifolia Choisy). Finally the record from French Guiana (here sub 'I. filicaulis') is indeed an isotype of I. leprieurii (see the specimen in G).
Neither Flora do Brasil 2020 nor SpeciesLink mention the species for Brazil.
