Crotalaria depauperata was described on the basis of four collections: “ Habitat in alpestribus tractus Adamantini Serra de S. Antonio dicti prov. Minarum: M.”, “ in Chapada prope Capellinha ejusdem prov.: A. de St. Hilaire ”, “ in prov. Goyazensis campis arenosis; Gardner 4113 ”, and “ ad Ribeirão da Prata: Pohl ”. All this material has been located and analyzed. Avendaño (2011) assigned the St. Hilaire material in K (K000500581) as lectotype of C. depauperata , referring to the additional specimen identification “ lectotype ” label assigned by Windler in 1980. We agree with this assessment and thus here formalize the choice of this material as lectotype of C. depauperata .

In his original description, Bentham (1839) cited the following syntypes for Crotalaria leptophylla “ Savannahs of the Rupunoony. Schomburgk. ” and “ On the Rio Preto, in Brasil. Pohl.” The Pohl material has not been located, but we have studied Schomburgk’s collections in the Kew herbarium. Windler assigned the material K000500565 as lectotype of C. leptophylla . We disagree with this assignment since the material K000500566 is the single specimen with the exact locality given in the protologue stated on its identification label. Therefore we here designate the latter material as lectotype.
