Note: Wilson & Rowe (2008) neotypified I. glandulosa . Wendland’s type of Indigofera glandulosa has not been located. De Kort &Thijsse (1984) cite the type as ‘Herb. Wendland (Hannover, destroyed)’ but Stafleu and Cowan (1988) indicate that Wendland’s types are at Göttingen (GOET) but the type of this taxon was not found in that herbarium (Jochen Heinrichs pers. comm. 2007). De Kort and Thijsse (1984: 120) suggest that Wendland’s type may have been a duplicate of the collection used by Willdenow when he later published the same name. These authors say ‘Willdenow referred to Roxburgh, who wrote this name on the herbarium label’ but this is not quite correct. Willdenow attributed the name to Roxburgh but the specimen itself was collected by Johann Gottfried Klein (an associate of Roxburgh’s) in November 1794. Furthermore, judging from Willdenow’s annotation, this specimen appears only to have reached Europe in 1802. Wilson & Rowe (2008) found that Roxburgh specimen in the Smith Herbarium (at LINN) is dated 1789 and is more likely to represent a duplicate of material Wendland may have seen. This seems a plausible scenario, but the uncertainties surrounding typification of this taxon have led to choose one element on the sheet at LINN as neotype rather than as lectotype.
