On the north side of Tower Street, at Pensdale Street, in the scrub there, an individual of Solidago gigantea (it has 3-nerved leaves, and its lower stem is somewhat glaucous and smooth, and the top of the stem, at the inflorescence, is hairy – also, it is losing its lower leaves) is flowering (with a terminal inflorescence).

Solidago rugosa is flowering along the old railroad embankment (west side) running south from Erie Avenue, just east of B St.
