Two dimensional thin layer chromatographic studies of Sarracenia L. petal extracts are reported for the first time. These are correlated with leaf extract chromatography (paper) by another author, and with other factors and problems in this genus. The author agrees that chromatographic studies by themselves are of little help in phyletic and phenetic studies in Sarracenia, except in some cases where they may be considered with other characters and factors. Petal extract chromatography did disclose that red-flowered species of the genus do have masked, underlying yellow and sometimes blue pigments which would presumably be visible to bee pollinators.
