“What is the selective advantage to plants of nyctinasty which closes flowers in the evening?”

“Other scientists suggest that in rainforest plants, nyctinasty allows for maximum daytime sun exposure while folding sheds excess water at night.”

“Darwin studied nyctinasty and hypothesized that it might protect against lower nighttime temperatures.”

“This will explain why attempts at explanation of the phenomenon of nyctitropism had hitherto proved so baffling.”

“Other words spelled in the competition were recidivist, nyctitropism, roulade, and limuloid.”
