Carl Linnaeus first showed his Systema Naturae to Isaac Lawson,a Scottish physician(later served in the British army) and Frederik Gronovius,a Dutch scholar and they liked it so much that they got it published at their own expense.

This forged a friendship between Linneaus and Lawson who corresponded with each other for quite some time .

When Lawson died in 1747 Linneaus named a genus after him,Lawsonia.

How do we better know the only species of this genus?
