acrogen

n. (Botany) flowerless plant that grows only from the tip of the stem

The name cryptogams (scientific name Cryptogamae) is a term fairly widely in use as a phrase of convenience, although regarded as an obsolete taxonomic term. The name cryptogams refers to plants (in the wide sense of the word) which reproduce by spores. Other names, such as "thallophytes", "lower plants" and "spore plants" are also occasionally used. The best known groups of cryptogams are algae, lichens, mosses and ferns .
