Notes.

Due to mislabeled herbarium specimens, Baillon (1891a) described Croton furcellatus as coming from Madagascar, thinking that the type specimen had been collected by Scott-Elliot in southern Madagascar. As pointed out by Humbert (1948), Perrier de la Bâthie (1948), and Arènes (1948), a shipment of plants collected in 1887 by Edward Palmer in Mexico was sent from K to P in 1890 and was mislabeled as being Scott-Elliot collections from Madagascar. The only Croton among these, # 180, is a collection of C. sonorae Torr. from Guaymas, Sonora, Mexico ( Watson 1889).
