Bitelaria is a monospecific genus of extinct vascular plants described from outcrops of the Early Devonian Campbellton Formation in New Brunswick, Canada and Middle Devonian outcrops in the Voronezh region of Russia.

[1] B. dubjanski is characterized by thick-walled, dichotomously branched tubular axes and thick cuticles with possible lenticel-like eruptions.

The unusual external morphology of the plant distinguishes it from other vascular plants and is thus placed in Tracheophyta incertae sedis.
