    Hello folks, I have run across a few more things I am hoping for help identifying, I will only put one plant per thread and wait time between threads. Thank you all for all of your help so far with this little personal endeavor.

    Here is the plant: It has purplish pink Flowers/Pods.

    So..., it's in the same family as Poison Sumac but not it? I can't find anything so far on R. copallinum being poisonous, and this was growing in a very dry field about 60 meters from a small pond. If it helps to understand how dry it was up there I was only moving about 7 miles per hour in this picture. and you can see how many of the leaves are drooping in the other pictures...., definitely not flooded or damp ground. I'd really like to be sure of the difference.

    So far this is what I've gotten from wikipedia on R. copallinum.

    and this is what I've found there on poison sumac.

    Poison sumac (Toxicodendron vernix or Rhus vernix) is a woody shrub or small tree growing to 7 m (20 ft) tall.[1] All parts of the plant contain a resin called urushiol that causes skin and mucous membrane irritation to humans. When burned, inhalation of the smoke causes diarrhea and other internal irritations.

    [edit] Description
    The head of the tree is round and narrow and the branches slender and rather pendulous; often it is simply a shrub. Small branches and young stems pithy. Has acrid, milky, poisonous juice which turns black on exposure.[1]

    The compound leaves are pinnate, 25-50 cm long, with 7 - 13 leaflets; the leaflets are 4-10 cm long and sometimes mistaken for individual leaves. The veins from which the leaflets grow are always red.

    The fruit is a small white or grey berry, produced in panicles 10-20 cm long; this distinguishes it from other sumacs which have red berries. Differs from other sumacs in having shorter leaves, leaflets fewer, margins are entire. It is found in wet soils, whereas the others like it dry.[1]

    Bark: Smooth, light or dark gray, slightly striate. Branchlets are smooth, reddish brown, covered with small, orange colored, lenticular spots; later they become orange brown and finally light gray.
    Wood: Light yellow with brown lines; light, soft, coarse-grained, brittle. Sp. gr., 0.4382; weight of cu. ft., 27.31 lbs.
    Winter buds: Terminal bud is much larger than the axillary buds, all are acute, dark purple.
    Leaves: Alternate, pinnately compound, seven to fourteen inches long, borne on slender reddish petioles. Leaflets seven to thirteen, obovate, or oblong, three to four inches long, slightly unequal or contracted at the base, entire, acute or rounded at the apex, short petiolate except the terminal one which sometimes has a stalk an inch in length. They come out of the bud orange colored and downy, when full grown are smooth, dark green and shining above, pale beneath; midrib and primary veins prominent. IN autumn they turn scarlet and orange.
    Flowers: June, July. Dioecious; yellow green, borne in long, narrow, axillary panicles crowded near the ends of the branches. Bracts and bractlets are acute, downy, and fall as the flowers open.
    Calyx: Five-lobed, lobes acute, short.
    Corolla: Petals five, acute, yellow green.
    Stamens: Five, with long slender filaments and large orange colored anthers. In the fertile flowers short and rudimentary.
    Pistil: Ovary ovoid-globose, one-celled, surmounted by three thick spreading styles; ovule solitary.
    Fruit: Drupaceous, globular, white, borne in long graceful racemes, often tipped with the dark remnants of the styles. Ripens in September and frequently hangs on the tree the entire winter. Cotyledons flat, leaf-like.[1]

    [edit] Distribution

    Poison sumacPoison sumac grows exclusively in very wet or flooded soils, usually in swamps and peat bogs, in the eastern United States and Canada.

    In the U.S., it can grow as far west as Idaho, where it is found only in the southern part of the state.


    [edit] Toxicity
    In the U.S., it is listed under the Federal Noxious Weed Act of 1974, as amended (7 U.S.C. 2801 et seq.), as a "noxious weed". Most U.S. states list this plant in similar categories. It is considered one of the "U.S. Invasive Weeds" [1]. In terms of its potential to cause urushiol-induced contact dermatitis, poison sumac is far more virulent than its relatives poison ivy and poison oak. According to some botanists, poison sumac (Toxicodendron vernix) is the most toxic plant species in the United States (Frankel, 1991).

    The poison shows itself in painful and long continued swellings and eruptions.[1]


    [edit] Avoidance, treatment, and safety
    For specific information on prevention and treatment of Toxicodendron rashes, see Urushiol-induced contact dermatitis.

    You can steep the fruit in hot water, strain it through a cheesecloth, and add sugar to make Indian lemonade. LINK
