title: Statistical evaluation of a number of glandular lipid constituents in ferns of three Dryopteris species.
abstract: The occurrence of various hydrocarbon, fatty acid and terpenoid constituents in glandular cells in the rhizomes of three Dryopteris fern species has been evaluated by statistical treatment of quantitative data from gas chromatographic analysis. The results obtained suggest complicated interrelationships, presumably resulting from the excretion process, between representatives of the three types of compounds. The species investigated show differences as to these interrelationships.
