Sphenophyta

Sphenophyta is a genus of vascular plants that is part of the kingdom, Plantae. Sphenophyta consists of only one genus, Equisetum, and they reproduce by spores rather than seeds. The term “Equisetum” comes from the fact that they can store granules of silica within its cells. Sphenophyta is also able to synthesize lignin and has apical growth (meaning that they use meristems to grow), similar to Pterophytes. Also on an interesting note, Sphenophyta can grow to be nearly fifteen feet tall.
