Summary Using paper chromatography, phenolic pigment profiles were established for each of 160 plants representing three species and various intermediate (“hybrid”) forms of Tiarella (Saxifragaceae). The 160 plants included two collections of 80 plants each, one collection made on July 13, the other on August 10 (1969). All plants were collected during anthesis from a sympatric population. The similarities of pigment profiles were determined by computer programming and were used as measurements of interspecific, intraspecific, and intraindividual variation, the latter represented by phenolic changes which occurred between collection dates. Consideration has been given to various phenomenona which might have induced intraindividual variation and its genetic regulation and application to systematics have been emphasized.
