John Cameron Semple (born 1947)[3] is a Canadian botanist and professor emeritus and adjunct professor at the University of Waterloo.[1]
He received a Bachelor of Science in 1969 from Tufts University, and a Master of Arts and Doctor of Philosophy from Washington University, St. Louis, in 1971 and 1972, respectively.[1]
He is known for his work on members of the tribe Astereae, particularly the multiple aster genera, goldenasters, and goldenrods.[4] He maintains the University of Waterloo Astereae Lab website.[1]
Semple's wife is named Brenda, and he named a new species Solidago brendiae (Solidago brendae) in honor of her.[5]:4
