Place of publication:
Syst. veg. 3:850. 1826 (A. Jussieu, Euphorb. gen. 28, 110, t. 7. 1824, nom. inval.; Rafinesque, Chlor. aetn. 4. 1813, nom. inval.)
Comment:
Rafinesque's combination cannot be valid, since the generic name was not validly published until 1824 (Melbourne ICN Art. 35.1); Jussieu did not validly publish this name either (Melbourne ICN Art. 35.2)
