in Thoreau’s Journal:
I am surprised to find arethusa abundantly out in Hubbards Close May be 2 or 3 days though not yet at Arethusa meadow prob on account of the recent freshet– It is so leafless that it shoots up unexpectedly
It is all color a little hook of purple flame projecting from the meadow into the air. Some are comparatively pale. This high colored plant shoots up suddenly all flower in meadows where it is wet walking.
