Thoreau writes in his journal:
The Rhodora Canadensis is not yet out of blossom, and its leaves are not expanded. It is important for its contrast with the surrounding green,—so much high-colored blossom. The Pyrus arbutifolia now. The ferns are grown up large, and some are in fruit, a dark or blackish fruit part way down the stem, with a strong scent,—quite a rich-looking fruit . . .
