• From the Greek “koris” (a bug) and “opsis” (indicating resemblance), referring to the seeds, which look like ticks.
• The Compositae or aster family is vast, with over 20,000 species, and is also one of the most developed families. It was named Compositae because the flowers are actually a “composite” of many individual flowers into one head. Hence, when children pull one “petal” off at a time, saying “she/he loves me, loves me not”, they are actually removing a complete flower, not just a petal.
• The specific epithet name “grandiflora” means large flowers.

Yuan et al. (1995) determined that this species requires 6 developed leaves on a stem before flower initiation can proceed.
