March 15, 1839. — John Edward Gray, Esq., F.R.S., President, in

 vations on the species of Tilia natives of England, with Notices of 

 some individual remarkable and aged Trees." The author stated that 

 he considered the Lime indigenous to Worcestershire, the borders of 

 Herefordshire, Gloucestershire, Monmouthshire and South Wales. 

 At Hainford, four miles north of Worcester, on the banks of the 

 Severn ; about the western base of the Berrow Hill, near Martley ; on

 wild keeping of nature. Mr. Lees had also observed the Lime grow-

 Rosebury Rock, and forming woods on the old Red Sandstone banks 

 above Knightsford Bridge, as well as covering in particular nearly the 

 whole of a large natural wood of 500 acres in extent at Shrawley, 

 eight miles north of Worcester, where for many years it has regu- 

 larly been cut down at intervals as underwood, and the pollarded 

 stumps are moss-covered and evidently of great age. It is also ap-
