The characters given above are taken from Gay's manuscript monograph of the 

 order, now at Kew. Gay described the species from an imperfect specimen, pre- 

 served in the Paris Herbarium. He does not quote any locality in the Annales des 

 Sciences Naturelles, and in his manuscript he simply says "Habitat in Brasilia."
