The fall dandelion in Tuttle's meadow.

August 26. 

The fall dandelion is as conspicuous and abundant now in Tuttle's meadow as buttercups in the spring. It takes their place. 

Saw the comet in the west to-night.

H. D. Thoreau, August 26, 1853

The fall dandelion is as conspicuous and abundant now August 4. 1854 ("The autumnal dandelion is now more common ");. August 24, 1852("Autumnal dandelions are more common now."); September 1, 1859 ("The autumnal dandelion is a prevailing flower now"); September 2, 1854("The autumnal dandelion is conspicuous on the shore."); September 13, 1856 (" Surprised at the profusion of autumnal dandelions in their prime . . .
