in Thoreau’s Journal:
[at C. Miles’ Blueberry swamp]
The men, women & children who perchance come hither blueberrying in their season––get more than the value of the berries in the influence of the scene–– How wildly rich & beautiful hang on high there the blueberries which might so easily be poisonous––the cool blue clusters high in air–– Choke berries––fair to the eye but scarcely palateable hang far above your head weighing down the bushes. The wild holly berry––perhaps the most beautiful of berries––hanging by slender threads––from its more light & open bushes––& more delicate leaves. The bushes 8 feet high are black with choke berries––and there are no wild animals to eat them. I cannot sufficiently admire the Rhexia one of the highest colored purple flowers––but difficult to bring home in its perfection––with its fugacious petals. The Hieracium scabrum is just opening. Large sheathed polygonum by the river with white flowers on a slender spike. Lechea racemulosa? Of Big[elow]––not in Gray––a fine almost leafless bushy––sometimes reddish low plant in dry fields.
