Stockmansella is a genus of extinct plants of the Middle Devonian (Eifelian stage, around 393 to 388 million years ago), fossils of which have been found in north-west Germany.

Both prostrate and upright stems have a central strand of conducting tissue which contains simple tracheids, so that Stockmansella is a vascular plant.

[3] The genus was created by Fairon-Demaret for fossil forms previously assigned to Taeniocrada but which differ in having single lateral sporangia.

[3] In 2004, Crane et al. published a cladogram for the polysporangiophytes, in which Stockmansella is placed in the Rhyniaceae, sister to all other tracheophytes (vascular plants).
