--><p>Plants of Isoëtes melanopoda with black leaf bases are typical. Plants without black leaf bases have been called I. melanopoda f. pallida (Engelmann) Fernald. Variation also occurs in megaspore morphology. A collection from Dallas County, Texas, has lustrous black leaf bases and boldly rugulate spores with ridges that occasionally anastomose. In many respects, I. melanopoda is similar to I. howellii.</p>
