Notes.

Unlike most other Malagasy Croton species described by Lamarck from Commerson specimens, there is no specimen of C. cassinoides found in the Lamarck Herbarium at P, so we designate the sheet in the general herbarium at P as lectotype. Most of Commerson's collections from Madagascar came from the Fort Dauphin area in Toliara Province, and all other specimens of C. cassinoides that we have determined are from near Fort Dauphin, so this is likely where the type came from. In the description of C. delphinianus ( Baillon 1891a), there was no collection or locality cited (it was the last in the section of Baillon's text and appeared to be cut off). In the descriptions of other new species in the same publication, the Latin description was always followed by a paragraph containing specimen information. At P there is a sheet [P00133052] that has a label with a note in ink stating " Croton cassinoides Lamk. et type du C. Delphinianus H. Bn." It also has a small envelope that reads " Croton Delphinianus Scott-Elliot. n. 1557 Fort-Dauphin." Based on that information, we designate it as lectotype for C. delphinanus .
