Lycopodium dendroideum is just shedding pollen.

C. says that he saw a loon at Walden the 15th. 

P. M.— To Lee's Cliff. 

The tupelo berries have all fallen; how long? 

Alternate cornel about bare. 

Hardhack half bare. 

Many witch-hazel nuts are not yet open. The bushes just bare. 

The slippery elm is nearly bare, like the common near it. 

Cedar berries, how long? 14th at least; probably by the time they lost their leaves. There is one sizable tree west by north of Lee's Cliff, near the wall. 

Lycopodium dendroideum (not variety) is just shedding pollen near this cedar. 

I see asparagus in the woods there near the cedar, four or five feet high! 

Find the seedling archangelica grown about two feet high and still quite green and growing, though the full-grown plants are long since dead, root and stalk. This suggests that no doubt much of the radical spring greenness is of this character, — seedlings of biennials, and perhaps more of them a persistent or late growth from a perennial root, as crowfoot, whiteweed, five-finger, etc. 

The scent of the archangelica root is not agreeable to me. The scent of my fingers after having handled it reminds me strongly of the musquash and woodchuck, though the root itself does not; so its odor must be allied to theirs. 

I find at Lee's Cliff, on the shelves and sides of the rocks, a new fern, apparently Cystopteris fragilis, more than half decayed or withered, though some fresher and shorter fronds at the base of the others are still quite green. It curls up so in my hat that I have difficulty in examining it. It is abundant thereabouts. 

Paddling up the river the other day, those (probably canoe) birches on Mt. Misery on the edge of the hill a mile in front looked like little dark clouds, for I could not distinguish their white trunks against the sky. 

Though the dark-blue, or ripe, creeping juniper berries are chiefly on the lower part of the branches, I see fresh green ones on old wood as big as a pipe-stem and often directly opposite to purple ones (!). They are strangely mixed up. I am not sure but some of this year's berries are already ripe. 

See a black and rusty hedgehog (?) caterpillar in the path.

H. D. Thoreau, Journal, October 19, 1859

The tupelo berries have all fallen. See September 30, 1854 ("I find a fine tupelo near Sam Barrett’s now all turned scarlet. I find that it has borne much fruit — small oval bluish berries, . . .."); October 6, 1858 (“The tupelo at Wharf Rock is completely scarlet, with blue berries amid its leaves”)

Lycopodium dendroideum (not variety) is just shedding pollen near this cedar.  See September 24, 1857 ("I find the Lycopodium dendroideum, not quite out, just northwest of this pine grove, in the grass. It is not the variety obscurum, which grows at Trillium Wood, is more upright-branched and branches round."); October 12, 1859 ("Now for lycopodiums (the dendroideum not yet apparently in bloom), the dendroideum and lucidulum, etc., — how vivid a green ! — lifting their heads above the moist fallen leaves.") October 17, 1857 ("The Lycopodium lucidulum looks suddenly greener amid the withered leaves."); November 11, 1859 ("The flat variety of Lycopodium dendroideum shed pollen on the 25th of October."); November 17, 1858 ("It would seem that these lycopodiums, at least, which have their habitat on the forest floor and but lately attracted my attention there (since the withered leaves fell around them and revealed them by the contrast of their color and they emerged from obscurity), —it would seem that they at the same time attained to their prime, their flowering season. "); November 7, 1858 ("I see Lycopodium dendroideum which has not yet shed pollen."); November 11, 1859 ("The flat variety of Lycopodium dendroideum shed pollen on the 25th of October."); November 15, 1858 ("The Lycopodium dendroideum var. obscurum appears to be just in bloom in the swamp about the Hemlocks (the regular one (not variety) is apparently earlier)."); November 17, 1858 ("Lycopodium dendroideum . . .was apparently in its prime yesterday); December 7, 1853 ("In the latter part of November and now, before the snow, I am attracted by the numerous small evergreens on the forest floor, now most conspicuous, especially the very beautiful Lycopodium dendroideum, somewhat cylindrical") See also A Book of the Seasons,  by Henry Thoreau, The Lycopodiums

C. says that he saw a loon at Walden the 15th. See October 8, 1852 ("As I was paddling along the north shore, after having looked in vain over the pond for a loon, suddenly a loon, sailing toward the middle, a few rods in front, set up his wild laugh")

Many witch-hazel nuts are not yet open. The bushes just bare. See October 19, 1856 ("Witch-hazel is in prime, or probably a little past, though some buds are not yet open. Their leaves are all gone.")

Find the seedling archangelica grown about two feet high and still quite green and growing, though the full-grown plants are long since dead. See September 4, 1856 ("Measured an archangelica stem (now of course dry) in Corner Spring Swamp, eight feet eight inches high, and seven and a quarter inches in circumference at ground. It is a somewhat zigzag stem with few joints and a broad umbelliferous top, so that it makes a great show. One of those plants that have their fall early")
