Macadamia nut + Black crowberry

Macadamia is a genus of four species of trees indigenous to Australia and constituting part of the plant family Proteaceae. They grow naturally in north eastern New South Wales and central and south eastern Queensland. Common names include macadamia, macadamia nut, Queensland nut, bush nut, maroochi nut, queen of nuts and bauple nut; and from Indigenous Australians' languages bauple, gyndl, jindilli, and boombera. Previously, more species, with disjunct distributions, were named as members of this genus Macadamia. Genetics and morphological studies more recently published in 2008 by Austin Mast and colleagues show they have separated from this genus Macadamia, correlating less closely than thought from earlier morphological studies.

Empetrum nigrum is a species of crowberry known as black crowberry which is native to most northern areas of the northern hemisphere, as well as the Falkland Islands in the southern hemisphere. In gardening, it can be grown in acidic soils in shady, moist areas. It can be used for the edible berries, for a purple dye, or as a ground cover. The metabolism and photosynthetic parameters of Empretrum can be altered in winter-warming experiments
