Abstract
MY attention has been directed to the letters in NATURE of October 20 and November 10 on the flight of thistledown. The explanation of the phenomenon observed seems to me to lie in the very slow air-currents which are sufficient to raise the pappose structures of many Compositæ, especially when it is only the pappus which is raised, the fruit having fallen off.
