Notes:

Can be mistaken for Poison Hemlock (Conium maculatum).  But this plant is smaller, its leaves are more feathery, and without the red blotches on the stems.  Note the ovoid fruit which have a beak about 1/3 of the body length, and small hooks which give the plant its common name.

Notes:

This small, inconspicuous plant has tiny flowers.  It has distinctive, slightly geranium-like leaves and weak trailing stems. Fruits are up to 2 mm across, ovoid/spheric, and inflated.

Notes:

Very common shade-loving plant, which produces a loose umbel of tiny white flowers. Note that there are no bractlets at the base of the flowers/fruits and that the fruits each have a long pedicel.

Notes:

Less common than Wood Sweet Cicely (Osmorhiza berteroi, see above).  The flowers are greenish-yellow, and subtended by noticeable bracts, which remain when the fruits develop.  Note that the pedicels of the fruits are very shor,t and that the fruits themselves are shorter and fatter than those of Wood Sweet Cicely.

Notes:

Notes:

Easily confused with Bur Chervil (Anthriscus caucalis, see above).  This plant’s leaves tend to be narrower, the inflorescence is smaller, the flowers can sometimes be pinkish, and the hairs on the fruits are noticeably longer on one side of the fruit. Sometimes known — for good reason — as Tall Sock Destroyer.

Notes:

The plant is similar in appearance to Field Hedge-parsley (Torilis arvensis, see above).  However, its inflorescence appears in sessile clusters in the nodes of the stems, and the fruits are bristly on only one side, the other side being smooth or pimply. Sometimes known as “Short Sock Destroyer”.

Notes:

This is less common than the two non-native Hedge-parsleys (Torilis sp. see above), and easily overlooked.  It has distinctive leaves: thread-like to linear, and pinnately dissected.  Also note the oblong fruits, slightly flattened front to back, with hooks similar to those of the non-native Hedge-parsleys.
