Abstract
The new names Mciveriella and Rhamnica are proposed to replace later homonyms, Harmsia McIver & Basinger and Rhamnites Forbes ex McIver & Basinger respectively. Rhamnites Newberry is restored as a valid genus, being synonymized with Amelanchites McIver & Basinger. Rhamnites Forbes ex Berry is re-classified as Berchemiopsis McGinitie. The new combinations Archeampelos lobatocrenata, Archeampelos nebrascensis, Berchemiopsis berchemiiformis, Mciveriella hydrocotyloidea, Rhamnica cleburnii, Rhamnica goldiana, Rhamnites asperus are proposed. Furthermore the illegitimate name Populus cordata Newberry (non Hort. ex Poiret) is lectotypified and transferred into Archeampelos with the new name A. yellowstonica.
