Rhynchospora stenophylla may occasionally be confused with the closely related R. rariflora but can be distinguished by its taller and wispier habit, its longer spikelets of narrower outline, and the distinctly longer fruit tubercle. Both species are usually found on wet substrates; R. stenophylla typically is found in the deepest bogs and sphagnous seeps.
