미국연영초-[정명]Trillium cuneatum Raf.

Trillium cuneatum, the little sweet betsy, also known as whip-poor-will flower, large toadshade, purple toadshade, and bloody butcher, is a species of flowering plant in the family Melanthiaceae. It is a member of the Trillium cuneatum complex, a subgroup of the sessile-flowered trilliums. It is native to the southeastern United States but is especially common in a region that extends from southern Kentucky through central Tennessee to northern Alabama. In its native habitat, this perennial plant flowers from early March to late April (depending on latitude). It is the largest of the eastern sessile-flowered trilliums.

Description

Trillium cuneatum is a member of the Trillium cuneatum complex, along with its closest relatives, Trillium luteum and Trillium maculatum. Trillium cuneatum is paraphyletic and morphologically variable. Some populations currently considered to be T. cuneatum are more closely related to T. maculatum than to other T. cuneatum populations. It may be split in the future into several monophyletic species with greater morphological uniformity. All members of the complex are sessile-flowered trilliums.

Trillium cuneatum is a perennial, herbaceous, flowering plant that persists by means of an underground rhizome. Like all trilliums, it has a whorl of three bracts (leaves) and a single trimerous flower with three sepals, three petals, two whorls of three stamens each, and three carpels (fused into a single ovary with three stigmas). It has a sessile flower (no flower stalk), erect petals, and mottled leaves. The broad leaves surround a banana-scented flower with maroon, bronze, green, or yellow petals. It is known for its morphological variability between (and even within) geographically distributed populations.
