Another new plant anticipated. Naming Ledum Swamp.



February 4. 

P. M. – To C. Miles Swamp. 

Discover the Ledum latifolium, quite abundant over a space about six rods in diameter just east of the small pond-hole, growing with the Andromeda calyculata, Polifolia, Kalmia glauca, etc. 

The A. Polifolia is very abundant about the pond-hole, some of it very narrow-leaved and dark, even black, above, as if burnt. 

The ledum bears a general resemblance to the water andromeda, with its dark reddish-purplish, or rather mulberry, leaves, reflexed; but nearer it is distinguished by its coarseness, the perfect tent form of its upper leaves, and the large, conspicuous terminal roundish (strictly oval) red buds, nearly as big as the swamp pink's, but rounded. The woolly stem for a couple of inches beneath the bud is frequently bare and conspicuously club-shaped. The rust on the under sides of the leaves seems of a lighter color than that of Maine. The seed-vessels (which open at the base first) still hold on. 

This plant might easily be confounded with the water andromeda by a careless observer. When I showed it to a teamster, he was sure that he had seen it often in the woods, but the sight of the woolly under side staggered him. 

There are many small spruce thereabouts, with small twigs and leaves, an abnormal growth, reminding one of strange species of evergreen from California, China, etc. 

I brought some home and had a cup of tea made, which, in spite of a slight piny or turpentine flavor, I thought unexpectedly good. 

An abundance of nesaea on the east edge of the pond-hole (call it Ledum Pond-hole); and is that a lysimachia mingled with it?

The ledum does not grow amid the maples, nor, indeed, does the A. Polifolia, Kalmia glauca, nor even the water andromeda abundantly. It bears no more shade than that of the spruce trees, which do not prevail over the above-named shrubbery. 

As usual with the finding of new plants, I had a presentiment that I should find the ledum in Concord. It is a remarkable fact that, in the case of the most interesting plants which I have discovered in this vicinity, I have anticipated finding them perhaps a year before the discovery.

H. D. Thoreau, Journal, February 4, 1858

Discover the Ledum latiforium ....The rust on the under sides of the leaves seems of a lighter color than that of Maine. See July 25, 1857 (“Here [at Kimeo], among others, were the . . . Oxalis Acetosella, still occasionally in flower; Labrador tea (Ledum latifolium), out of bloom; Kalmia glauca, etc., etc., close to the track. ”); August 24, 1857 (“We waded into Coos Swamp on the south side the turnpike [at Natick] to find the ledum, but did not succeed. ”); June 19, 1856 (“Looked at a collection of the rarer plants made by Higginson and placed at the Natural History Rooms. Among which noticed ...Ledum latifolium, from White Mountains, rather 'broader—leafed than mine from Maine.”)  ~~ Recently reclassified from the genus Ledum, labrador-tea (Rhododendron groenlandicum) is a diminutive shrub of cool, wet swamps, spruce forests, and muskeg. It is recognized by its clusters of tiny white flowers and its folded-under leaves with brown hairs on the undersides. This shrub is named Labrador-tea because its aromatic leaves were commonly brewed as a tea by northern native Americans. Moose browse the leaves and twigs. ~ Go Botany

The A. Polifolia is very abundant about the pond-hole, some of it very narrow-leaved and dark, even black, above, as if burnt. See February 12, 1858 ("There is, apparently, more of the Andromeda Polifolia in that swamp than anywhere else in Concord."); November 15,1857 ("At C. Miles Swamp [f]ind plenty of Andromeda Polifolia ... where you can walk dry-shod in the spruce wood”). See also July 14, 1853 (“Saw something blue, or glaucous, in Beck Stow's Swamp to-day; approached and discovered the Andromeda Polifolia, in the midst of the swamp at the north end, not long since out of bloom.): February 17, 1854 ("In the open part of Gowing's Swamp I find the Andromeda Polifolia. Neither here nor in Beck Stow's does it grow very near the shore.)

This plant might easily be confounded with the water andromeda by a careless observer. See August 19, 1856 (“a careless observer would look through their thin flowery panicles without observing any flower at all.”)

There are many small spruce thereabouts, with small twigs and leaves, an abnormal growth, See November 15,1857 ("At C. Miles Swamp .. where you can walk dry-shod in the spruce wood”); February 12, 1858 ("About the ledum pond-hole there is an abundance of that abnormal growth of the spruce. . . , which have an impoverished look, altogether forming a broom-like mass, very much like a heath."); June 13, 1858 ("I see a song sparrow's nest here in a little spruce just by the mouth of the ditch."); August 8, 1858 ("The peculiar plants of [Ledum] swamp are, then, as I remember, these nine: spruce, Andromeda Polifolia, Kalmia glauca, Ledum latifolium, Gaylussacia dumosa var. hirtella, Vaccinium Oxycoccus, Platanthera blephari glottis, Scheuchzeria palustris, Eriophorum 'vaginatum.");' September 6, 1858 ("That swamp is a singularly wild place, without any natural outlet. I hear of a marsh hawk’s nest there this summer. I see great spiders there of an uncommon kind, whose webs —the main supporting line — stretch six feet in the clear from spruce to spruce, as high as my head, with a dense web of the usual form some fifteen inches in diameter beneath."); October 23, 1858 ("The spruce is changed and falling, but is brown and inconspicuous. A man at work on the Ledum Pool, draining it, says that. . . he had found three growths of spruce, one above another, there.")

It is a remarkable fact that, in the case of the most interesting plants which I have discovered in this vicinity, I have anticipated finding them perhaps a year before the discovery. See  July 14, 1853 (“Saw something blue, or glaucous, in Beck Stow's Swamp to-day; approached and discovered the Andromeda Polifolia, in the midst of the swamp at the north end, not long since out of bloom. This is another instance of a common experience. When I am shown from abroad, or hear of, or in any [way] become interested in, some plant or other thing, I am pretty sure to find it soon. Within a week R. W. E. showed me a slip of this in a botany, as a great rarity which George Bradford brought from Watertown. I had long been interested in it by Linnaeus's account. I now find it in abundance.”); January 9, 1855 (“Make a splendid discovery this afternoon. Walking through Holden’s white spruce swamp, I see peeping above the snow-crust some slender delicate evergreen shoots very much like the Andromeda Polifolia, amid sphagnum, lambkill, Andromeda calyculata, blueberry bushes, etc., though there is very little to be seen above the snow. It is, I have little doubt, the Kalmia glauca var. rosmarinifolia.”);  September 2, 1856 (“It commonly chances that I make my most interesting botanical discoveries when I am in a thrilled and expectant mood, perhaps wading in some remote swamp where I have just found something novel and feel more than usually remote from the town. Or some rare plant which for some reason has occupied a strangely prominent place in my thoughts for some time will present itself. My expectation ripens to discovery. I am prepared for strange things.”); November 4, 1858 ("We cannot see any thing until we are possessed with the idea of it, and then we can hardly see anything else. In my botanical rambles I find that first the idea, or image, of a plant occupies my thoughts, though it may at first seem very foreign to this locality, and for some weeks or months I go thinking of it and expecting it unconsciously, and at length I surely see it, and it is henceforth an actual neighbor of mine. This is the history of my finding a score or more of rare plants which I could name.”); August 22, 1860 ("I never find a remarkable Indian relic but I have first divined its existence, and planned the discovery of it. Frequently I have told myself distinctly what it was to be before I found it.”); and note to July 2, 1857 ("We find only the world we look for.")

A journal, a book that shall contain a record of all your joy.
"A stone fruit. Each one yields me a thought." ~ H. D. Thoreau, March 28, 1859


I sit on this rock
wrestling with the melody
that possesses me.
