(1849: 265, t.13) Type (further designated here) :— BRAZIL . Ceará State , northern Brazil [ August 1838 ] (fr), Gardner 1829 ( lectotype : P [ P 734721 , digital image!]; isolectotypes : BM [ BM 993266 , BM 993268 , digital image!], F [ F V0067809 F , F V0067810 F (fragment), digital image!], G [ G 437671 , G 437672 , digital image!], K [ K 585025 , K 585026 , digital image!], MO [ MO 216274 , digital image!], NY [ NY 324228 , NY 324229 , NY 324230 , digital image!], OXF [ OXF 98255 , digital image!], P [ P 734718 , P 734719 , P 734720 , digital image!], US [ US 102471, digital image!]) . Notes:— Brandbyge (1986: 557) stated that four sheets represent the lectotype , i.e. Gardner’s collection (no. 1829). We located these four sheet at P ( P 734718, P 734719, P 734720, and P 734721) and all bear a Brandbyge label reading “ Lectotype ”. Further, Gardner 1829 specimens were found in other herbaria ( BM , F , K , G , MO , NY , OXF , and US ). These specimens are isolectotypes . According to the Art. 9.17 of ICBN , Brandbyge’s proposal represent an initial but incomplete typification, and we here complete the designation of the type specimen by designating the individual specimen P 734721. A final note on the collection number, which was incorrectly reported in the protologue. Weddell (1849: 265) reported “1629” as the collection number.However, the lectotype and all the isolectotype report “1829”.This discrepancy is recorded in an handwritten note on NY 324230 (bottom of the sheet) highlighting that the discrepancy first appears in Meisner's (1855) treatment of Polygonaceae in Martius' Flora Brasiliensis and later repeated in Candolle's ( Meisner 1856 ) Prodromus . Brandbyge (1986) seems to have been aware of this and cites both of these Meisner works.
