Xanthium orientale Linnaeus, Species Plantarum, ed. 2, 2: 1400. 1763.

"Habitat in China, Japonia, Zeylona." RCN: 7155.

Lectotype (Jeanmonod in Gamisans & Jeanmonod, Compl. Prodr. Fl. Corse, Asteraceae I: 190. 1998): Herb. Linn. No. 1113.2 (LINN) . - Epitype (Wisskirchen in Jarvis & Turland in Taxon 47: 369. 1998): France. Perigord, rechtes Ufer der Dordogne bei Bezenac, 14 Sep 1987, Wisskirchen 230 (BM-000576318; iso- BOCH).

Current name: Xanthium orientale L. ( Asteraceae).

Note: Löve & Dansereau (in Canad. J. Bot. 37: 174, f. 2. 1959) noted the material on sheet 1113.2 (LINN) as immature and evidently did not consider it as the type. However, Jeanmonod (in Compl. Prodr. Fl. Corse, Asteraceae I: 190. 1998) treated 1132.2 (LINN) as the type, citing Löve & Dansereau. This choice (before Mar 1998) pre-dates that of Wisskirchen (in Taxon 47: 369. May 1998) but the latter’s additional choice of an epitype stands. See discussion of the complex by Jeanmonod (in Candollea 53: 446. 1998), who notes the epitype choice. Wisskirchen (Standardliste Farn-Blütenpfl . Deutschl.: 550 (1998) gives a further review.
