Nomenclatural notes. – The authorship of Peltophorum dasyrhachis has been cited incorrectly in the literature (most often as “(Miq.) Baker” or “(Miq.) Kurz ex Baker”, even in recently published treatments (e.g. RUDD, 1991 ; DEZHAO & al., 2010 ). The error stems from authors overlooking KURZ (1876) as the first person to validly transfer the basionym Caesalpinia dasyrhachis Miq. to Peltophorum , and consequently recognizing a superfluous combination published by BAKER (1878) . Kurz’s article was issued on 14 November 1876 , whereas Baker’streatment was not published until July1878 . Baker’s publication further confused the situation by modifying the original orthography of the epithet and acknowledging Kurz via the citation “ P. dasyrachis , Kurz MSS.” Miquel’s original spelling should be retained as stipulated in Art. 60.1 of the ICBN ( MCNEILL & al., 2006 ). Typification . – In the protologue the provenance of the species was given as “Sumatra orient. in prov. Lampong, prope Mengala, Kebang (T.)”. LARSEN & al. (1980) and later HOU (1996) cited an unnumbered Teijsmann duplicate from Sumatra at L as the holotype and a K sheet as an isotype, but unique identifiers (e.g.,accession number,specific locality) for the types were not provided in either publication. We have examined two unnumbered Teijsmann sheets at L [L0019200, L0019201] with red “Type” stickers. Both were annotated by Ding Hou in 1993 as Peltophorum dasyrhachis , but the precise type status (e.g., holotype, isotype, syntype) was not indicated on either sheet. Sheet [L0019201] bears a handwritten label including the general locality “Lampongs” and a “Herbarium Dr. J. K. Hasskarl” stamp, whereas [L0019200] has a typewritten label noting “Sumatra” and “Ex Herbario Miquel”. None of the annotations on either L sheet belong to Miquel. Conversely, we have examined two numbered Teijsmann collections from Sumatra at U that were originally part of Miquel’s private herbarium ( Teijsmann 4322HB [U0003298]; Teijsmann 4547HB [U0003297]). Both of the collections were annotated by Miquel as Caesalpinia dasyrhachis . The original handwritten label of [U0003298] was annotated as “Kebang, Lampongs”, whereas the label of [U0003297] was annotated as “Mangala, Lampongs.” The labels and plants of the two Teijsmann collections at U match the information given in the protologue, suggesting that at least two different collections (i.e., syntypes) were used for the protologue description. The U sheets are treated as syntypes and the two L sheets may represent duplicates of the U collections, or could even be additional syntype material. No effectively published lectotypification statementshave been found for Caesalpinia dasyrhachis . Teijsmann 4547HB [U0003297] includes flowers and is in good condition and is designated here as lectotype. The other syntype is in fruit.
