| Identification | Ditch Fimbry differs from other fimbries by its solitary spikelet per stem, and by the color of the spikelet: pale red-brown in life, straw color after pressing. | |
| Taxonomic Comments | Plants of the the genus Fimbristylis are very small to tall (3+ feet), with most leaves in a basal tuft, and an open, branched, terminal inflorescence. The spikelets are various shades of rufous, chestnut, or brown (due to the color of the scales) and resemble tiny pinecones. Important key characters include size, shape, and ornamentation of the achenes (seeds); see also other characters used by Weakley (2018). Godfrey & Wooten (1979) have excellent drawings and descriptions. | |
