Arisaema dracontium (L.) Schott
Green dragon, Dragonroot, Greendragon
Synonym(s): Muricauda dracontium
USDA Symbol: ardr3
USDA Native Status: L48 (N), CAN (N)
Green Dragon has only 1 leaf; however, the leaf stem forks so that there appear to be 2 separate leaves, each divided into 5Ė15 unequal leaflets which are arranged palmately (like the upturned palm of oneís hand) on the tip of the forked stem, which is sometimes 20 inches long. A separate flower stalk hold the perennialís unique blossom. 1 greenish, long-tipped spadix (the dragonís tongue) protruding several inches beyond a narrow green spathe. It is a narrow, greenish, hooded, cylinder with a long, upward-pointing tongue. There are numerous tiny flowers crowded onto the 6-inch-long flower stem, the lower part of which is enclosed within the leaf stem. The white flowers are very small, with no petals or sepals. Orange-red berries follow.
The long tapered tip of the spadix resembles a large flickering lizards tongue. (Lamb/Rhynard) Green Dragon is considered relatively rare.
