Delightful Linnaeus, who dearly loved his little joke, himself confesses to have named the day-flowers after three brothers Commelyn, Dutch botanists, because two of themcommemorated in the two showy blue petals of the blossompublished their works; the third, lacking application and ambition, amounted to nothing, like the inconspicuous whitish third petal! Happily Kaspar Commelyn died in 1731, before the joke was perpetrated in “Species Plantarum.” Soon after noon, the day-flower’s petals roll up, never to open again.
