He studied at Sydney University, receiving a first class honours degree in 1948. Lawrie Johnson's abilities and interests were wide ranging. He is foremost known for his expertise on the eucalyptus genus.
However, he also knew much of rainforest botany, particularly the myrtle family. For instance his name is credited against Syzygium crebrinerve, Syzygium corynanthum, Choricarpia subargentea, Syzygium francisii, Syzygium moorei and others. Lawrie Johnson also collected the type material for the endangered Illawarra Socketwood, which was named in his honour, Daphnandra johnsonii. Many other plants were also named johnsonii after him.
