Joseph Louis Gay-Lussac
"Gaylussacia" is named in honor of the French chemist Joseph Louis Gay-Lussac (1778–1850). It is closely related to "Vaccinium", and it is still unclear whether the commonly understood line between "Vaccinium" and "Gaylussacia" is justified. A 2002 paper found that molecular data did not support past divisions of "Gaylussacia" into sections.
