The witch-hazel at Lee's Cliff.

September 29.

Cool and windy. Wind roars in the trees. 

Viola cucullata, Aster puniceus and longifolius still.

Solidago speciosa out in Hubbard's Swamp since I went away, say ten days ago. This must be a late one, then. 

Diplopappus linariifolius, Aster undulatus, and a few small ones.  

Red oak acorns fall.

The witch-hazel at Lee's Cliff, in a fair situation, has but begun to blossom; has not been long out, so that I think it must be later than the gentian. Its leaves are yellowed.

Barberry ripe.

Sumachs and maples changed, but not trees generally.

Bluets still.

Viburnum Lentago berries yet.

Lambkill blossoms again.

H. D. Thoreau, Journal, September 29, 1853

Viola cucullata. See September 9, 1858 ("Many Viola cucullata have opened again"); September 12, 1851 ("Found a violet, apparently Viola cucullata, or hood-leaved violet, in bloom in Baker's Meadow beyond Pine Hill."); September 28, 1852 ("I find the hood-leaved violet quite abundant in a meadow, and the pedata in the Boulder Field.  I have now seen all but the blanda, palmata, and pubescens blooming again. . . This is the commencement, then, of the second spring. Violets, Potentilla Canadensis, lambkill, wild rose, yellow lily, etc., etc., begin again") See also A Book of the Seasons, by Henry Thoreau, the Violets

Aster puniceus and longifolius still. See August 30, 1856 ("The Aster puniceus is hardly yet in prime; its great umbel-shaped tops not yet fully out"); September 1, 1856 ("A. longifolius, hardly one seen yet.”); September 15, 1856 ("Aster longifolius and puniceus . . . in prime"); . October 7, 1857 ("Crossing Depot Brook, I see many yellow butterflies fluttering about the Aster puniceus, still abundantly in bloom there.");  October 8, 1856 ("Of asters, only corymbosus, undulatus, Tradescanti, and longifolius . . .are common."); October 30, 1853 ("Along the Depot Brook, the great heads of Aster puniceus stand dry and fuzzy and singularly white, — like the goldenrods and other asters, — but some quite low are still green and in flower"); November 3, 1853 ("The Aster puniceus by brook is still common, though the worse for the wear, — low and more recent ones, — so that this, though a week ago it was less prevalent, must be set down as later than the A. undulatus. It bears the frosts much better, though it has been exposed to more severe ones from its position. And with this must be included that smooth and narrower- leaved kind, in other respects the same, one of which, at least, I think I have called A. longifolius. They seem to run into each other. I am inclined to think it a smoother A. longifolius"); November 5. 1855 ("Crossing the Depot Field Brook, I observe the downy, fuzzy globular tops of the Aster puniceus. They are slightly tinged with yellow, compared with the hoary gray of the goldenrod")

Solidago speciosa. . .This must be a late one. See September 15, 1854 (“Solidago speciosa at Clamshell out several days”); . September 27, 1856 (“To Clamshell by boat. Solidago speciosa not quite out!!”) October 2, 1856 ("Solidago speciosa completely out, though not a flower was out September 27th)

Diplopappus linariifolius. See August 3, 1858 ("Savory-leaved aster.");  August 4, 1851 ("a bluish "savory-leaved aster.""); August 22, 1859 ("The savory-leaved aster (Diplopappus linariifolius) out; how long?"); September 18, 1856 ("Diplopappus linariifolius in prime."); October 10 1858 ("Pulling up some Diplopappus linariifolius, now done")

Aster undulatus. See  September 20, 1852 ("Aster undulatus, or variable aster, with a large head of middle-sized blue flowers.");   October 2, 1859 ("The A. undulatus looks fairer than ever, now that flowers are more scarce."); October 6, 1858 ("the Aster undulatus is now very fair and interesting. Generally a tall and slender plant with a very long panicle of middle-sized lilac or paler purple flowers, bent over to one side the path. ");; October 25, 1858 ("The Aster undulatus is now a dark purple (its leaves), with brighter purple or crimson under sides.");   November 3, 1858 ("Aster undulatus is still freshly in bloom"); November 7, 1858 ("Aster undulatus and several goldenrods, at least, may be found yet.")

Red oak acorns fall. See September 12, 1854 (“The red oak began to fall first.”); October 12, 1858 (“Acorns, red and white (especially the first), appear to be fallen or falling")

The witch-hazel at Lee's Cliff must be later than the gentian. See September 29, 1857 ("I hear that some have gathered fringed gentian."); See also  September 18, 1854 ("Fringed gentian near Peter’s out a short time, . . ., it may after all be earlier than the hazel.”); September 18, 1856 ("Unquestionably the gentian is now far more generally out here than the hazel."); September 18, 1859 ("From the observation of this year I should say that the fringed gentian opened before the witch-hazel"); October 1, 1858 ("The fringed gentians are now in prime."); October 2, 1853 ("The gentian in Hubbard's Close is frost-bitten extensively. As the witch-hazel is raised above frost and can afford to be later, for this reason also I think it is so.")  See also 

Witch-hazel in prime,

Yellow leaves by their color

conceal the flowers.

October 4, 1858

 October 4, 1858 ("Witch-hazel apparently at height of change, yellow below, green above, the yellow leaves by their color concealing the flowers. The flowers, too, are apparently in prime. The leaves are often richly spotted reddish and greenish brown. ") And also A Book of the Seasons by Henry Thoreau, The Fringed Gentian; A Book of the Seasons, by Henry Thoreau, The Witch-Hazel

Barberry ripe. See September 29, 1854 ("Now is the time to gather barberries"); --  See also August 23, 1853 ("Barberries have begun to redden,");  September 12, 1851 ("The pendulous, drooping barberries are pretty well reddened. I am glad when the berries look fair and plump"); September 13, 1856 ("The barberries are abundant there, and already handsomely red, though not much more than half turned"); September 13, 1852 ("The barberries, now reddening, begin to show.”). September 16, 1852 ("The barberries are red."); September 16. 1857 ("Barberries very handsome now.

Sumachs and maples changed, but not trees generally. See September 20, 1852 (“The smooth sumachs are turning conspicuously and generally red, apparently from frost, and here and there is a whole maple tree red, about water.”)

Bluets still. See August 26, 1856 ("Bluets still.")

Viburnum Lentago berries yet. See A Book of the Seasons, by Henry Thoreau, Viburnum lentago (nannyberry)

Violets, Potentilla Canadensis, lambkill, wild rose, yellow lily, etc., etc., begin again")
