The species authority for Trillium erectum is Carolus
Linnaeus. Trillium erectum has petals that are usually marroon or
white, with anther the same color. Its leaves are unmottled, shaped
from rhombic to rhombic-ovate and 8-18 cm long with width 6-25 cm.
The leaves are short-petiolate to sessile, usually wider than long.
The stems are 2-5 dm in height and purplish to green in color. Its
rhizome are 2-6 cm long and 10-25 mm in diameter. Trillium erectum
has berries which are dull red or purple, ellipsoid to ovoid in shape,
and 1.5-2.5 cm long. The pedicels are 1-9 cm long and erect or divergent.
The sepals are horizontal and 2-4 cm long, 0.7-1.5 cm wide. The stamen
are 0.8-1.5 cm long, filaments 2.7 mm long, and the stigma is maroon or
rarely white. The whit variation of Trillium erectum is hard to distinguish
from Trillium cernuum. The two species can be seperated by the length
of the filaments or the maroon colored ovary of Trillium erectum (Radford,
Albert E. et al., 1968).
The holotype is located at the Harvard University Herbarium in Stockbridge,
Massachusetts. The type locality of the specimen is rich woods.

It has a
foul odor, similar to that of rotting meat, to attract carrion flies for
pollination.
This species is an angiosperm, or flowering plant. The figure
below describes the life cylcle of an angiosperm.
You
can find Trillium erectum in rich woodlands, near a shady moist area around
April to June.
