in Thoreau’s Journal:

There are some fine large clusters of lambskill close to the shore of Walden and in the Peak fronting the south–– They are early there & large ap. both on account of the warmth & the vicinity of the water –– These flowers are in perfect cylinders sometimes 6 inches long by 2 wide––and 3 such raying out or upward from one centre i.e. 3 branches clustered together.
