Abstract
SOME time ago, when I was carrying out some investigations concerning the behaviour of plants, I came across the statement, in Sir J. E. Smith's "English Flora" (1829), that the flowers of the coltsfoot (Tussilago farfara) are "drooping in the bud". The statement surprised me because, although I had been observing the behaviour of this plant fairly closely over a number of years, both in its wild state and under controlled conditions, I had never once seen it produce flower buds that could in any sense be called drooping. As it was inconceivable that the coltsfoot had changed its behaviour since 1829 I could only conclude that the great botanist was in error; and there the matter was allowed to rest.
