Type material of Paliurus colombii Heer, Populus arctica Heer, Hakea arctica Heer, and Hedera
macclurii Heer from the Atanikerdluk locality (Paleocene, Greenland) was restudied based on the original
collection, stored in the National Museum of Ireland, Dublin. All these species were joined under the name
Zizyphoides colombii (Heer) Seward et Conway, type species of the genus Zizyphoides Seward et Conway. A lectotype
of Zizyphoides colombii is designated and the diagnosis of this species is emended. An emended diagnosis
of the genus Zizyphoides is also presented.
