From the Supplement (Vol. V)

The largest known specimen of P. sinensis grows at Caerhays, Cornwall, and measured 49 × 3[3/4] ft in 1971. But it has attained 35 × 3 ft (1984) at Burford Lodge, Dorking, Surrey, where it was probably planted by Sir William Lawrence, son of Sir Trevor Lawrence, who was President of the Royal Horticultural Society from 1885 until his death in 1913.
