An extensive suite of C 14 -C 18 hydroxylated fatty acids of cutin origin was identified among the nonlignin CuO reaction products from tissues of 67 different plant species. These mid-chain and -hydroxylated cutin acids together accounted for 0.5 to 4% of the organic carbon (OC) in these nonwoody vascular plant tissues and were produced in characteristically different yields by the various plant types. Nonvascular plants, including bulk phytoplankton, kelps, mosses, and liverworts, did not yield measurable amounts of cutin acids, except for trace levels of -hydroxytetradecanoic acid detected in kelps. Most of the "lower" vascular plants, such as clubmosses and ferns, produced simple cutin acid suites composed mainly of -hydroxy C 14 and C 16 acids. Gymnosperm needles yielded cutin acid suites dominated by C 16 acids, in which 9,16- and 10,16-dihydroxyhexadecanoic acids were characteristically abundant. Relatively high yields of C 18 acids were obtained from angiosperm tissues, among which dicotyledons exhibited a predominance of 9,10,18-trihydroxyoctadecanoic acid over all the other C 18 acids. The Chromatographie peak corresponding to dihydroxyhexadecanoic acid was a mixture of the positional isomers 8,16-, 9, 16-, and 10,16-dihydroxyhexadecanoic acids, whose relative abundances uniquely characterized monocotyledon tissues and distinguished among different types of gymnosperm tissues. Based on the cutin acid yields obtained from the different plant types, several geochemical parameters were developed to distinguish up to six different cutin-bearing plant groups as possible components of sedimentary mixtures.
