|discussion=<p><i>Carex alma</i> has an unusual combination of characteristics for the section. The conspicuous basal sheaths, the basally spongy perigynia tapering to beak, the hyaline acute scales, and the cylindricly enlarged style bases place the species closer to sect. Vulpinae than to other taxa of sect. Multiflorae. <i>Carex</i> agrostoides, here placed in synonymy with <i>C. alma</i>, has previously been distinguished by the green perigynia and absence of basal spongy tissue. All such specimens, including the type, appear to be immature specimens of <i>C. alma</i> in which spongy tissue and mature perigynium coloration have not developed.</p>
