in Thoreau’s Journal:

The maples begin to be ripe. How beautiful when a whole maple on the edge of a swamp is like one great scarlet fruit––full of ripe juices–– A sign of the ripening––every leaf from lowest limb to topmost spire-is a-glow.

The flattened black berries of the cucumber root––with the triangular bases of its leaves tinged red beneath as a sort of cup for them.
