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."

The data presented in Figs 3 and 4 indicate that the effect of the spatial variation in cryptogam cover will vary with the susceptibility of the exposed areas to detachment.
In Scott's view, the great advantage of Pringsheim's interpretation was that it "would enable us to understand the existence of the immense and unbridged gulf which separates the sporophytes of the Muscineae from that of the Vascular Cryptogams. The latter might well have been derived from ancestors, in which the 'first neutral generation' had never suffered the extreme reduction which characterise it in the Moss series, but had always retained its vegetative organs."
Flagellated sperm occur in bryophytes, vascular cryptogams, and some groups of gymnosperms (cf.

He organised major expeditions to survey for cryptogams, including fungi, in Wilsons Promontory National Park in 1996 and 1998; and led a similar expedition by the FNCV's Fungi Research Group to Mt Buffalo National Park in 1997.
Another way to say this is that the cryptogams, especially the fungi and liverworts and mosses that Edgeworth includes, require a denser palette of color than the watercolor washes and occasional pen outhnes that were at the time conventional, especially among amateur botanical artists.
Vascular cryptogams, especially ferns, have not been very favourable material for tissue culture because their vascular system is made up of highly differentiated tissues that are difficult to proliferate into cell masses capable of growth in vitro [10].
Epiphylls are usually small cryptogams growing on the upper surfaces of the host leaves [8] and commonly consist of two dominant visible groups: epiphyllous liverworts and foliicolous lichens (referred to as liverworts and lichens) [9].
The gallery forest shelters 3-30 meter high trees and it is characterized by high moisture and rich herbaceous vegetation, essentially cryptogams and epiphytes.
