Rhynchospora rariflora, commonly called fewflower beaksedge, is a species of flowering plant in the sedge family (Cyperaceae). It is native to North America, where it is found in the southeastern United States, Mexico, Belize, Honduras, Nicaragua, and the West Indies. Its typical natural habitat is sandy or peaty areas, in wet savannas, seeps, and bogs. Rhynchospora rariflora is a densely tufted perennial with delicate, lax stems. Its leaves are nearly thread-like. Its inflorescence is loose and sparsely flowered. In the northern area of its range it fruits from late spring to summer, while in the southern area it is reproductive year-round. It is similar to Rhynchospora stenophylla, from which Rhynchospora rariflora can be distinguished by having bristles that are shorter than the achene body, and by its smaller tubercle.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Rhynchospora rariflora has left across the world's sequence archives.

Where the DNA of Rhynchospora rariflora was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
