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."

Scott wrote "There is no reason to believe that the Bryophyta, as we know them, were the precursors of the vascular Cryptogams at all.
Overall, comparison between Figs 3-5 indicates that the response of a surface covered with cryptogam will differ considerably from one where the zones act as sediment traps or sinks.
On the other hand, such points as sporophyte dependency on the gametophyte in bryophytes and (to a lesser extent) in vascular cryptogams, the occasional reversion of vegetative to sporogenous tissue, and the usually striking dissimilarity of the gametophyte and the sporophyte in the life cycle of a given plant are seemingly more cogent arguments--and these arguments rather plainly suggest an antithetic origin of sporophytes of land plants.
Cryptogams (mosses, lichens, liverworts) are abundant in the pastures and appear to make a substantial contribution to surface soil protection.
The canopy of towering champion-sized trees provides the perfect environment for cryptogams such as mosses, liverworts, ferns, fungi, and especially the myxomycetes.
The species count included 220 different plants, 75 species of birds, 65 different insects, 51 cryptogams (mosses and lichens), assorted mollusks, herptiles and arachnids, plus three mammals and three fish.

Cryptogams and trees are altogether missing, even the variety of herbs is larger in pollen records, so only the finds of seeds of Urtica dioica and Ranunculus sceleratus do not have corresponding pollen taxa.
The vegetation is mostly dominated by slow growing perennial, herbaceous and shrubby vascular plants and extensive mats of cryptogams (mosses, lichens etc.
