Nuts
Macadamia tetraphylla
B tier
Macadamia tetraphylla is the rough-shell macadamia species of eastern Australia, less dominant in global bulk orchards than integrifolia but important in hybrids and some regional plantings. Kernels can be richly buttery with slight flavour differences from smooth-shell standards; shell texture and tree habits diverge more than snack-tin branding usually admits. Specialty and breeding programs still value the species for genetics and local product stories. Expect buttery high-oil meats when well processed. Judge lots on aroma and colour like any macadamia. Useful for Australian origin diversity and hybrid parentage (e.g. Beaumont lines). Keep cool after shelling. Not always labelled at retail—when it is, treat it as a species cue rather than a freshness certificate.

History
Aboriginal Australians ate macadamia nuts from native eastern forests.
Colonial botanical interest began cultivation pathways for macadamia.
Rough-shell macadamia remained part of breeding and regional plantings beside integrifolia.
Hybrids and specialty orchards continued to use tetraphylla genetics.
