Zosterophyllum
Encyclopedia
Zosterophyllum was a genus of Silurian-Devonian land plant with branching axes.
Some species have been transferred to other genera:
A cladogram published in 2004 by Crane et al. places the species of Zosterophyllum in a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids
(living and extinct clubmosses and relatives).
Some species have been transferred to other genera:
- Z. artesianum to DanziellaDanziellaDanziella is a genus of extinct vascular plants of the Early Devonian . Fossils found in the Artois region of northern France were first described as Zosterophyllum artesianum, but a later review by Edwards showed that they did not fit the circumscription of that genus.-Description:Compressed...
artesiana - Z. contiguum to DemersathecaDemersathecaDemersatheca is a genus of extinct vascular plants of the Early Devonian . Fossils were first found in the Posongchong Formation of eastern Yunnan, China. The plant had smooth leafless stems at least 1 mm in diameter, but only regions which bore spore-forming organs or sporangia are well-known...
contigua - Z. subverticillatum to AdoketophytonAdoketophytonAdoketophyton is a genus of extinct vascular plants of the Early Devonian . The plant was first described in 1977 based on fossil specimens from the Posongchong Formation, Wenshan district, Yunnan, China. These were originally named Zosterophyllum subverticillatum; later the species was...

Lycopodiophyta
The Division Lycopodiophyta is a tracheophyte subdivision of the Kingdom Plantae. It is the oldest extant vascular plant division at around 410 million years old, and includes some of the most "primitive" extant species...
