Aarabia is a genus of extinct vascular plants found in central Morocco in outcrops of Early Devonian age (Emsian, around 411 to 393 million years ago).

[1] Fossils were found in an outcrop believed to be of Emsian age (around 410 to 390 million years ago) northwest of the town of Azrou in central Morocco.

Meyer-Berthaud and Gerrienne were unable to decide whether these short branches were generally capable of further growth or had ceased to grow and were adapted for some particular function.

The generic name is derived from the locality close to Jbel ben Aarab, near Azrou in Central Morocco.

[1] Meyer-Berthaud and Gerrienne added Aarabia to the data set which had been used by Kenrick and Crane in their analysis of the phylogeny of the polysporangiophytes,[2] and generated a new phylogenetic tree.
