Plant microfossils from Kootenay coal-measures strata of British Columbia

Plant microfossils from roof shale and shale-parting strata of the Kootenay coal-bearing formation of southeastern British Columbia are described and illustrated. The microfossils are affiliated as follows: 2 fungi, 1 bryophyte, 3 lycopsids, 12 ferns, 11 gymnosperms, 2 angiosperms, and 14 with uncertain botanical relationships. Techniques of maceration, mounting, and photomicrography are discussed. The microflora is related to the macroflora from the same formation, and compared briefly with similar microfloras from Europe and the U. S. S. R. The comparison suggests a closer age relationship to the Upper Jurassic than to the Lower Cretaceous.
