Quercus arcoglandis Kellogg

Some references interpreted the name as published to be a typographical error and amended it to Q. acroglandis, which is how it is listed in Flora of North America, as a synonym of Q. agrifolia. This presumably was based on the assumption that Kellogg was referring to the long point of the acorns (acro derives from Ancient Greek ἄκρων (ákrōn) and means “sharp”). However, the original spelling may likely be correct and derive from the Latin arcus meaning “bow” or “arch”, referring to the arrangement of the acorns, which are sometimes fanned out in the shape of an arch, or like the spokes of a cowboy spur, which would explain Kellogg’s common name “Spur Acorn Oak” (Al Keuter pers. comm., via Allen Coombes). (See here.)

This name antedates Q. wislizeni. A proposal should be prepared to conserve Q. wislizeni against Q. arcoglandis
