GREEN PITCHER PLANT
(Sarracenia oreophila)
FAMILY: Sarraceniaceae
STATUS: Endangered, Federal Register, September 21, 1979; effective April 7, 198O).
DESCRIPTION AND REPRODUCTION: The green pitcher plant is a perennial
herb which lives, to some extent, on
decaying insects and leaves which have fallen into the pitcher-like
leaves. Its rhizomes are 1 to 1.5 centimeters thick. The leaves
are 2O to 75 centimeters long, and 6 to 1O centimeters in circumference
at the orifice. These leaves usually appear with the
flowers or before, gradually narrowing from the orifice to the base,
rarely conspicuously winged, externally glabrous, green to
yellow-green. The plant's hood is 2 to 8 centimeters long, reniform
to obovate, strongly revolute at the base, internally
gladular-pubescent, purple-reticulate, purple spotted at the base,
or yellowish-green. Its phyllodia is 5 to 18 centimeters long,
and .5 to 3.5 centimeters wide, persistent, and more numerous than
the leaves. Its scape is 45 to 7O centimeters long. The
petals are 4 to 5.5 centimeters long, and yellow. The style-disk is
5 to 8.5 centimeters wide, and yellow.
Flowering reaches its peak from Mid-April to early June. Ants, pollen-eating
beetles, bumblebees, honey bees, Sarracenia flies,
and assorted number of wild bees of several species are the most frequent
visitors to pitcher plant flowers. Vegetative
reproduction from root stocks may also occur.
RANGE AND POPULATION LEVEL: This plant is presently restricted to areas
of the Cumberland Plateau and the Ridge
and Valley Province in northeast Alabama, and to the Blue Ridge of
Georgia and North Carolina. There are a total of 34
naturally occurring populations including 31 in Alabama, one in Georgia,
and two in North Carolina. Populations in Alabama
occur in the Coosa Valley area (Cherokee and Etowah Counties), and
on Sand Mountain (Dekalb, Etowah, Marshall, and
Jackson Counties). In Georgia (Towns County) and North Carolina (Clay
County), sites are in the Lake Chatuge area.
Historical populations are documented for Elmore County, Alabama; Fentress
County, Tennessee; and Troup, Taylor, and
Chattooga Counties, Georgia. Most of the sites are small in terms of
area occupied by plants and number of individuals.
Population sizes range from one to several hundred individuals, with
most having fewer than 5O plants.
HABITAT: The habitats of extant populations of the green pitcher plant
vary somewhat, including mixed oak or pine
flatwoods, seepage bogs, and streambanks (Little River). Fire appears
to play a major role in the maintenance of extant
populations in seepage bogs and mixed oak flatwoods.
REASONS FOR CURRENT STATUS: Like many other carnivorous plants, the
green pitcher plant is often collected for
commercial sale. Because of its limited range, collecting has a heavy
impact on these plants and in some areas has caused the
complete disappearance of the species. Since Alabama has no state laws
protecting rare, endangered, or threatened species,
regulatory mechanisms to prevent removal by collectors are essentially
nonexistent. Increased residential, agricultural, and
silvicultural development, as well as fire suppression, further threaten
populations.
MANAGEMENT AND PROTECTION: Sites where the green pitcher plant grows
must be carefully managed to prevent
degradation and to insure that natural processes, such as fire, continue
to occur. Nursery inspections might be carried out to
monitor commercial stocks and quarantine officials could be helpful
in controlling interstate and international shipments.
