Apperton ; Melv. 28. There are some fine hawthorns now in the 

 Eegent's Park, which are probably the same as those mentioned with 

 admiration by Pepys in his Diary,

First record: Blackstone, 1737. Loudon (loc. eit. 888) says that the 

 oldest pear trees in the neighbourliood of London are at Twickenham, 

 where are some 50 to 60 ft. high, and with trunks 18 in. to 3 ft. in 

 diameter. No doubt often not native, but accidentally sown from 

 orchard pears. The specimen in Herb. Harr. labelled P. communis 

 seems a foreign Pyrus allied to Aria,
