Quercus × morehus
Hybrid species of oak tree
From Wikipedia, the free encyclopedia
Quercus × morehus,[3] Abram's oak in Kellogg's original description[4] (later called oracle oak by Jepson[5]), is a named hybrid between the red oaks Quercus kelloggii (California black oak) and Quercus wislizeni (interior live oak).[6] Originally published as the unique species Quercus morehus by Kellogg [4] rather than as the hybrid it is called today [6] this tree is found in the US states of California and possibly southern Oregon,[7] usually where the territories of the purported parents overlap.[3]

Because the name Q. × morehus was adopted before 1980, while Q. wislizeni and Quercus parvula were still considered conspecific[8] it is often applied not only to trees appearing intermediate in form between Q. kelloggii and Q. wislizeni but also to 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.[9]
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.[3]
