Eleocharis erythropoda Steudel, Red-stemmed spikerush
Eleocharis erythropoda is sparse in Renfrew County. It can be confused as an immature or diminutive form of E. palustris but E. erythropoda only has one sterile scale (Figure 2) as compared to two or more sterile scales found on E. palustris. Eleocharis erythropoda also has slightly inflated leaf sheaths. Erythropoda means "red stemmed" but red stems are also frequent on E. palustris so it is not diagnostic.
