my vote goes to Platanthera dilatata. A North American native terrestrial. It is found in Alaska, Canada, the western mountain states and most of the northern tier states. It is very common in Alaska. It has a delicious cinnamon - clove fragrance.
Brassavola grandiflora - I can't describe it other than "spicy floral";
Meiracyllium trinasutum (miniature relative of Cattleya) - very nice cinnamon fragrance
