1 82 TREES AND SHRUBS 



PRUNUS Of these, the Cherry and Bird Cherry,* 

 Plum,* Bullace,* and the beautiful P. triloba are a

PTELEA TRIFOLIATA. 



PYRUS. P. Aria* (the White Beam tree), P. Aucu-

 P. Sorbus * (Service tree). 



QUERCUS (Oak). The most satisfactory species 

 are Q. sessilifoKa* and Q. pedunculata. These gene-

 laciniata* and Q. lucombeana* are also beautiful trees. 

 We must also mention the Evergreen Oak (Q. Ilex)* 

 alba, palustris, laurifolia, coccinea (Scar)et Oak), Suber 

 (Cork Oak), conferta.
