A new species of oak, Quercus delgadoana

An oak in cultivation as Quercus eugeniifolia has now been described as a new species,  Quercus delgadoana S. Valencia, Nixon & L. M. Kelly (Novon June 2011)

Pleistocene clone of Quercus palmeri Engelm.

The distribution of Palmer's oak (Quercus palmeri Engelm.) includes numerous isolated populations that are presumably relicts of a formerly larger range that has contracted due to spreading aridity following the end of the Pleistocene.
