Taxonomy Names and phrases in higher level categories used as formal knowledge representations for autonomic inferences and certain types of reasoning. Exemplified by the taxonomic tree classifying animals and plants (pp- 29,30).

Methyl ethers of several cyclitols occur as secondary substances in many higher plants. Attempts to use their occurrence for chemical taxonomy have been made (137). Sequoyitol (5-O-methyl-myo-inositol) is found in all families of gym-nosperms, and only in gymnosperms, although its distribution appears to be sporadic (137). It has been found in wood, bark, and cambial sap (114). D-Bornesitol (1-O-methyl-myo-inositol) is present in the latex of trees in the Apocynaceae family and in the wood of Sarcocephalus diderrichii (see 137). Dambonitol (1,3-di-O-methyl-myo-inositol) has been found in Gabon (Castilloa elastica) rubber latex (see 137).
