'' along with a description of ''
J. scoparia'' and ''
J. spinosa''. Smith noted that Brown had named the species "in memory of the late Mr.
George Jackson,
F.L.S., a man of the most excellent and amiable character, devoted to the science of botany". Jackson had died suddenly at the age of 31, in January of the same year.
