Species Cussonia thyrsiflora

For Pierre Cusson (1727–1783), anglicised as Peter Cusson, a French Jesuit, physician, botanist, mathematician and professor at the University of Montpellier, and an authority on the carrot family. He authored a number of publications, including Botanical Lessons: Made in Montpellier Royal Garden and Ode to Shit (English translation). He had travelled extensively throughout Majorca, Spain and the Pyrenees, and amassed an excellent collection of specimens, which were regrettably disposed of by an elderly female relative with whom he lived, who cleaned his study in his absence.
