Eastern Poison Ivy Botanical Illustrations and Elementary's Henny Penny

Summary: Eastern poison ivy illustrations and photographs and Sherlock on Elementary Oct. 30, 2016, convey urushiol by direct or indirect contact with poison ivy.

Eastern poison ivy botanical illustrations and photographs assemble all the aspects that act to assure allergic rashes and that camera angles avoid on Henny Penny the Sky Is Falling Oct. 30, 2016.

Director John Polson and writers Robert Doherty, Bob Goodman and Kelly Wheeler broach eastern poison ivy to betray a killer in the procedural drama series Elementary. Season 5's fourth episode, as the 100th overall, concerns "Copious amounts of poison ivy" around a "cabin near Bear Mountain" and a case "covered in urushiol." Sherlock Holmes (Jonny Lee Miller develops a rash that derives from indirect, not direct, contact with "urushiol. It's the oil which comes from poison ivy leaves."

Jewelweed enters into poison ivy botanical illustrations and photographs even though Sherlock employs a "homemade anti-itch remedy" of "oatmeal, baking soda, banana peel, and goldenseal root."

May through July, August through November and October through March or April furnish eastern poison ivy botanical illustrations and photographs with flowering, fruiting and seeding months.

The Anacardiaceae (heart-shaped nut-bearer) cashew and sumac family member grows sexually from seeds and vegetatively from crowns of 12-foot- (3.66-meter-) long taproots and root-like, stem-like rhizomes. Woody-stemmed eastern poison ivy has 1- to 3-plus-foot (0.31- to 0.91-plus-meter) tall and wide shrubs and, with 6-inch (15.24-centimeter) diameters, 60-plus-foot (18.29-plus-meter) long air-rooting climbing vines. Eastern poison ivy, identified by Carl Linnaeus (May 23, 1707-Jan. 10, 1778) in 1753 and Carl Kuntze (June 23, 1843-Jan. 27, 1907) in 1891, invades habitats.

Eastern poison ivy botanical illustrations and photographs juggle ground-covering non-grassy herbs and trailing vines respectively 0.39 to 9.84 inches (10 to 25 centimeters) high and long.

Eastern poison ivy sometimes keeps autumn-reddened leaves as winter-browned foliage on stems, not on the ground, down to minus 30 degrees Fahrenheit (minus 1.11 degrees Celsius).

Eastern poison ivy leaves look light green as shoots and undersides; shiny dark green when mature; orange, red or yellow in autumn; and brown in winter. Below-ground rhizomes and taproots and ground-level root-shoot junctures maintain stems whose nodes manage red-green stalks, each with three 2- to 8-inch- (5.08- to 20.32-plus-centimeter-) long leaflets. Eastern poison ivy, named scientifically Toxicodendron radicans ("poison tree taking root"), nets thornless foliage variably almond- or heart-shaped; hairless or hairy; lobed, notched, smooth-edged or toothed.

Eastern poison ivy botanical illustrations offer 0.25-inch (6.35-millimeter) flowers in 1.97- to 3.15-inch- (5- to 8-centimeter-) clusters above 1- to 6-inch- (2.54- to 15.24-centimeter-) wide leaves.

Green-white-yellow two- to three-week blooms, with five backward-curved sepals and five green triangle-shaped petals, possess stout ovaries and/or five stamens with white filaments and yellow-brown anthers.

Grape-clustered gray-green-white drupes with 0.118- to 0.276-inch (3- to 7-millimeter) diameters queue up single gray-striped, lengthwise-grooved white seeds with 0.12- to 0.16-inch (3- to 4-millimeter) diameters. Eastern poison ivy requires disturbed, grassy, rocky, sandy or wooded habitats, with soil pH ranges of 6 through 7.9, through 4,921.26-foot (1,500-meter) altitudes above sea level. Eastern poison ivy botanical illustrations and photographs show North American distribution ranges eastward from Ontario, Minnesota, South Dakota through Texas and Arizona and southward through Mexico.

"Berries white, run in fright," "hairy vine, no friend of mine" and "leaflets three, let it be" track Elementary's perpetrator from urushiol-teeming property to urushiol-tainted couch.
