    synonymous with Cellulares, is of a doubtful meaning. In adopting the word Cryptogams, which was originally applied rather by tact than knowledge, but is not by the progress of science exempt from the reproach of being merely superficial, I feel rejoiced not to transgress the maxim of Fries, which I believe to be deeply founded:—Ohuracteres essentiales plerumque maxime absconditi et acute inquirendi, cwm accidentales simul maxime superficiales.

Cellular, or more rarely cellulari-vascular, flowerless plants, often destitute of stem and foliage, propagated by simple or compound microscopic spores, germinating by means of one or more simple threads, and rarely containing any embryo, sometimes producing a prothallus, which gives rise to secondary spores or young embryonic plants, increasing mostly by ad- ditions to the external surface, exhibiting sexual distinctions, diclinous or monoclinous, but never producing true stamens or pistil, and consequently possessing no true pollen, but on the contrary, impregnated by spermatozoids, either provided with or destitute of slender flagelliform motile appendages. These characters may be expressed nearly in the terms which have been applied to the whole class by authors, each of which contains much truth, modified by more or less rare exceptions. 1.
