Solidago flexicaulis L.1 of 8
July 31, Stony Brook Reservation, Boston
zigzag goldenrod
Even in its non-blooming stage, this goldenrod is readily
recognizable in rich lowland woods by its slightly zigzag
stems and distinctive leaves: broadly ovate to elliptic,
coarsely and sharply serrate, each abruptly contracted to a winged
petiole.
