While this division is a small and inconspicuous group of plants today, in the Carboniferous some lycophytes were forest-forming trees more than 35 meters tall. Lycophytes are the oldest extant group of vascular plants, and dominated major habitats for 40 million years. ]]></termNote><termCreatedDate>2026-03-30 20:25:10</termCreatedDate><relation><relationType>UF</relationType><termId>31316256</termId><termName>club-mosses</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31316257</termId><termName>lycopodiophytes</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31316252</termId><termName>Division Lycophyta</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31316253</termId><termName>club moss</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31316254</termId><termName>club mosses</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31316255</termId><termName>club mosses and tree scales</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31303676</termId><termName>Plantae</termName><termType>PT</termType></relation></term>  </Zthes>
