What is that small conyza-like aster,?

July 19. 

Clematis has been open a day or two. 

The alisma will open to-morrow or next day. 

This morning a fog and cool.

What is that small conyza-like aster, with flaccid linear leaves, in woods near Boiling Spring? 

Some woodbine, cultivated, apparently long since flowered. The same of some on Lee's Cliff, where it is early.


H. D. Thoreau, Journal, July 19, 1853

Clematis has been open a day or two. See July 14, 1853 ('The Clematis  [by the Heywood Brook](near the water-plantain) will open in a day or two.")

This morning a fog and cool. See July 22, 1851 ("The season of morning fogs has arrived. . . .These are our fairest days, which are born in a fog."); July 22, 1854 ("Fogs almost every morning now."); July 25, 1852 ("the sun having risen, I see great wreaths of fog far northeast, revealing the course of the river.")

What is that small conyza-like aster, with flaccid linear leaves?. See July 18, 1854 ("Methinks the asters and goldenrods begin, like the early ripening leaves, with midsummer heats."); July 26, 1853 ("I mark again, about this time when the first asters open. . . This the afternoon of the year."); July 28, 1852 ("Goldenrod and asters have fairly begun; i. e. there are several kinds of each out. ") [Note; Conyza (horseweed, butterweed or fleabane) is a genus of flowering plants in the sunflower family.

Woodbine, long since flowered. See September 12, 1851 ("What we call woodbine is the Vitis hederacea, or common creeper, or American ivy.")
