Cassia centijuga Wawra , Flora 47: 248. 1864 . Type :— BRAZIL . Rio de Janeiro : Cantagallo , prov. Rio de Janeiro , Peckolt 228 ( lectotype designated here: W-0028997 [image!]; isolectotypes: W-0028994 [image!], W-0028995 [image!], W-0028996 [image!]). Lectotype available at: https://w.jacq.org/W0028997 Accepted name. Senna multijuga var. verrucosa (Vogel) H.S. Irwin & Barneby (1982: 496) . Notes . Cassia centijuga was described based on the collection Peckolt 228 , although there is no indication in the protologue about where the holotype was deposited. According to Ostermeyer (1907 -1908), Theodoro Peckolt donated a collection of 303 specimens of plants collected in 1860 for the Flora do Brasil to the Herbarium of Wien. We were able to locate four specimens of the collection Peckolt 228 deposited in the Wien Herbarium (W), all of which have annotations in Wawra’s handwriting on the identification labels, which is clear evidence that they are specimens from the collection referred to in the original description. The specimens of the collection Peckolt 228 are well preserved, with fully expanded leaves; two specimens (W-0028994 and W-0028995) have only apparently ripe fruits; two specimens have flowers, one with only a few flowers (W-0028996); specimen W-0028997 has complete inflorescences with well-preserved flowers. According to the protologue, the main characters used for description of Cassia centijuga were the number of leaflets, type of inflorescence, and floral characters of the androecium and gynoecium. Those characters are present in specimen W-0028997, and it is designated here as the lectotype .
