Sarracenia pitcher plants are known for both their carnivorous
habit and brightly colored leaves. Wild-type individuals normally
contain anthocyanin pigments in flowers and/or leaves. Plants which
completely lack anthocyanin have been found in several populations of pitcher
plant species in the Gulf Coast. This anthocyanin deficiency is caused
by a recessive allele (green) involved in a biochemical step between leucocyanidin
and pseudobase. Wild-type leaf extracts in acidified methanol turn
red whereas the mutant remains unchanged. Confirmation of the mutant
can be performed by boiling the methanolic extract in 4N HCL and observing
a red solution. We hypothesized that investigation of western Florida
pitcher plant bogs would result in the discovery of this plant. Searches
by the junior author during 1998 in a Liberty County, Florida S. purpurea
ssp. venosa var. burkii population resulted in the discovery
of several individuals of this rare mutant. This discovery represents
an addition to the flora of Florida.
