durmast oak

Etymology
Superficially a compound of, but the origin of durmast is unclear and possibly a result of scribal error. The first edition Oxford English Dictionary suggests that Thomas Martyn's dictionary for gardeners and botanists (1798) originated the word through misreading  ("light-brown acorn"), an interpretation also suggested by some earlier works going back to at least 1836, although a connection to  has also been suggested.
