Quercus × morehus,[2] Abram's oak in Kellogg's original description[3] (later called oracle oak by Jepson[4]), is a named hybrid between the red oaks Quercus kelloggii (California black oak) and Quercus wislizeni (interior live oak).[5] Originally published as the unique species Quercus morehus by Kellogg,[3] rather than as the hybrid it is called today,[5] this tree is found in the US states of California and possibly southern Oregon,[6] usually where the territories of the purported parents overlap.[2]
Because the name Q. × morehus was adopted prior to 1980 while Q. wislizeni and Quercus parvula were still considered conspecific[7] it is often applied not only to trees appearing intermediate in form between Q. kelloggii and Q. wislizeni but also those that could be Q. kelloggii × Q. parvula. Pending formal description the name Q. × ‘wootteni’ (Wootten's oak) has been proposed for the California black oak (Q. kelloggii) × Shreve oak (Q. parvula var. shrevei) hybrid.[8]
Quercus × morehus is a hybrid between a deciduous oak and an evergreen oak. Leaves are generally deciduous or partially deciduous and intermediate in form between Q. kelloggii and Q. wislizeni.[2]
