Sturdy Sedge

Carex alma L. H. Bailey

Comments

provided by eFloras
Carex alma 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. Carex agrostoides, here placed in synonymy with C. alma, 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 C. alma in which spongy tissue and mature perigynium coloration have not developed.

Carex alma

provided by wikipedia EN

Carex alma is a species of sedge known by the common name sturdy sedge. It is native to the southwestern United States and northern Mexico, where it grows in moist spots in a number of habitat types. This sedge forms a thick clump of thin stems up to 90 centimeters in length and long, thready leaves. The leaves have basal sheaths with conspicuous red coloration, often spotting. The inflorescence is a dense to open cluster of many spikelets occurring both at the ends of stems and at nodes. Each cluster is up to 15 centimeters long and 1 to 2 wide. The plant is sometimes dioecious, with an individual sedge bearing either male or female flowers. The female, pistillate flowers have white or white-edged bracts. The male, staminate flowers have visible anthers 2 millimeters long or longer. The fruit is coated in a sac called a perigynium which is gold to dark brown in color and has a characteristic bit of spongy tissue at the base.
