Linnaeus’ Floral clock ~ Linnaeus observed over a number of years that certain plants constantly opened and closed their flowers at particular times of the day, these times varying from species to species. Hence one could deduce the approximate time of day according to which species had opened or closed their flowers. Arranged in sequence of flowering over the day they constituted a kind of floral clock or horologium florae, as Linnaeus called it in his Philosophia Botanica, 1751.
