cryptogam,

in botany, term used to denote a plant that produces spores, as in algaealgae
[plural of Lat. alga=seaweed], a large and diverse group of primarily aquatic plantlike organisms. These organisms were previously classified as a primitive subkingdom of the plant kingdom, the thallophytes (plants that lack true roots, stems, leaves, and flowers).

, but not seeds. The term cryptogam, from the Greek kryptos, meaning "hidden," and gamos, meaning "marriage," was coined by 19th-century botanists because the means of sexual reproduction in these plants was not then apparent. In contrast, in the seed plants the reproductive organs are easily seen; the seed plants have accordingly been termed phanerogams, from the Greek phaneros, meaning "visible."

Cryptogam species range from generalists to specialists in terms of habitat preferences (McCune and Geiser, 1997;
Cryptogams (mosses, lichens, liverworts) are abundant in the pastures and appear to make a substantial contribution to surface soil protection.
Frequencies of forbs ([F.sub.(1,57)] = 11.20, P = 0.002) and cryptogam crusts ([F.sub.(1,57)] = 126.90, P [less than] 0.001) were greater in lightly than heavily grazed areas.
In cryptogam tundra, the peat is the result of the growth and accumulation of bryophytes together with cyanobacteria, algae, diatoms, and, occasionally, lichens.
Generally, expectations are that, at equilibrium, the ratio of the erosion rates for cryptogam covered and completely bare soil surfaces ([C.sub.r]) should be given by the equation:
