|discussion=<p><i>Carex capillaris</i> is somewhat variable and is often divided into two infraspecific taxa. Plants from the south are larger, have pale brown pistillate scales, and serrulate perigynium beaks. Northern plants are smaller, have medium brown pistillate scales, and smooth perigynium beaks. These characteristics are only weakly correlated, making it difficult to assign individuals to these taxa except in a very arbitrary manner. When recognized, the southern plants are called subsp. capillaris (C. chlorostachya Steven, <i>C. capillaris</i> <i></i>var.<i> major</i> Drejer ex Blytt), and the northern plants are called subsp. fuscidula (V. I. Kreczetovicz ex T. V. Egorova) Á. Löve & D. Löve.</p><!--
--><p>T. V. Egorova (1964) recorded the Asian species <i>Carex</i> delicata C. B. Clarke (as C. karoi) from Colorado; no specimens have been seen that confirm that report, and it seems likely an error because T. V. Egorova (1999) indicated the species is restricted to Asia. This species has dense lateral spikes with 15–30 perigynia, the perigynia rounded at the apex and abruptly beaked, with the beak 0.1–0.2 mm.</p><!--
--><p><i>Carex</i> tiogana D. M. Taylor & J. Mastrogiuseppe from northern California cannot be satisfactorily distinguished from <i>C. capillaris</i>, although it possesses an uncommon combination of characteristics. It is probably best treated as a variety or subspecies of <i>C. capillaris</i>. Until a more satisfactory account of the variability in C. tiogana and its relationship with <i>C. krausei</i> is produced, its status must remain uncertain.</p>
