The Kentia Palm, Howea fosteriana, also known as the palm court palm or thatch palm is, as you might expect, a member of the Palm Family, Arecaceae, native to the Lord Howe Islands, which lie 500 miles to the north east of Sydney, Australia.
My thanks to Antonin from Evian (the town, not the bottled water company) for the French translations of items in the cruet at the Holmfield Arms.
