"Xanthosoma jacquinii Schott, nom. illeg." is mistakenly given as a synonym of X. undipes (K. Koch & C. D. Bouché) K. Koch; it should instead appear in the synonymy of X. sagittifolium (L.) Schott. This error traces to our misunderstanding of Koch’s remarks in Bonplandia (Hannover) 4: 3 (1856), where Alocasia undipes K. Koch & C. D. Bouché was formally transferred to Xanthosoma. There, Koch makes the case that his X. undipes is identical to X. jacquinii "in hort. Schoenbr. nec in melet."; in other words, the plants grown by Schott at Schönbrunn under the name X. jacquinii were misidentified (at least in Koch’s view), and actually represented X. undipes. We got this right, taxonomically speaking, in applying the name X. undipes based on Schott’s color plate labeled as X. jacquinii. Nomenclaturally, however, X. jacquinii is a superfluous renaming of Arum xanthorrhizon Jacq. (presumably to avoid a near-tautonym), for which the correct name in Xanthosoma is X. xanthorrhizon (Jacq.) K. Koch. The Manual lists X. xanthorrhizon as a synonym of X. sagittifolium (correctly, we think), and that is where X. jacquinii must also be (automatically) referred. ORCHIDACEAE. We somehow bungled the authorship for Maxillaria angustissima Ames, F. T. Hubb. & C. Schweinf. (correct as just given). Our apologies to Mr. Hubbard! TOP
