W. zhichangensis W.Q.Zhu & Kenrick (1999)[1] Wenshania is a genus of extinct vascular plants found in the Posongchong Formation, Yunnan, China, which is of Early Devonian age (Pragian, around 413 to 411 million years ago).

[1] Wenshania is clearly related to the broadly defined group of zosterophylls, as it had flattened, oval to reniform sporangia which were attached to the sides of stems on short stalks and which released spores by splitting into two valves along a thickened border.

[1] The genus was described later than the publication of the cladistic studies by Kenrick and Crane which have been the foundation for much of the phylogeny of early land plants.

[2] It falls outside the core clade of zosterophylls (Zosterophyllopsida sensu Kenrick & Crane), whose members have sporangia arranged in two rows and new growths with coiled tips.

The authors of the genus say that Wenshania most closely resembles Gumuia found in the same stratum,[1] whose current phylogenetic placement in a paraphyletic group basal to the core zosterophylls can be seen in the summary cladogram shown below.
