47. Mimosa tarda Barneby

48. * Mimosa tenuipendula Burkart

Known to Barneby (1991) only from limestone outcrops from the valley of the Rio Paraguay in the vicinity of Puerto Cascadas in Dept. Boquerón, Paraguay. A single collection from the dry valleys of Cochabamba (C. Antezana C 1257, BOLV) is apparently attributable to this species, but it remains very poorly known and very sparsely represented in collections.
