Dwarf cultivars can be ideal for a small garden. Here are three "mini oaks". 

A new species of oak, Quercus delgadoana

An oak in cultivation as Quercus eugeniifolia has now been described as a new species (Novon June 2011).  

 
Quercus delgadoana S. Valencia, Nixon & L. M. Kelly (Fagaceae), a new species from the states of Hidalgo, Puebla, and Veracruz in the Sierra Madre Oriental, Mexico, is described and illustrated. Its morphological similarity to Q. eugeniifolia Liebm. (not known to be in cultivation), Q. sapotifolia Liebm., Q. salicifolia Née, Q. laurina Bonpl., and Q. affinis Scheidw., with which it shares narrowly lanceolate leaves and fasciculate stipitate trichomes in the axils of the secondary veins on the underside of the lamina is discussed. A dichotomous key is provided to distinguish these species.
