Description Laxly caespitose, diminutive, base of shoots more or less thickened. Acaulescent or fertile culms 0.4–2 cm × 0.3–0.7 mm, trigonous, slightly scabrid towards terminal spike. Basal sheaths brown, splitting into fibres. Leaf-blades 3–7 cm × 0.3–1 mm, longer than stems, linear, flat or slightly V-folded. Inflorescence 1.3–1.8 cm long, crowded, with 2–3 sessile spikes, overlapping. Proximal-most bract 2.5–7.7 cm × 0.6–3 mm, leaf-like, longer than the inflorescence; distal-most bract 1–3.3 cm × 0.3–1.2 mm, needle-like, longer than the spike. Spikes 0.3–0.7 cm × 1.4–4.5 mm, ovate, obovate, or subglobose, staminate portion usually non-conspicuous and concealed by the utricles, utricles ascending to spreading. Pistillate glumes 2.2–4 × 1.1–2 mm, obovate to elliptic, hyaline to whitish with a greenish middle band, aristate, constricted to attenuated towards the apex, the middle ones with a 1.1–2.2 mm awn, antrorsely scabrid. Stigmas 3. Utricles 2–5 × 0.8–2.2 mm, obovate to elliptic, trigonous, whitish proximally, greenish distally, laxly pubescent, hair mainly on the nerves, with 3–24 ± conspicuous but not elevated secondary nerves, ± attenuated proximally into a sub-stipitated base 0.6-1.1 mm long, constricted at the apex into a short beak 0.1–0.6 mm long. Nutlets 1.3–3.5 × 0.9–2.2 mm, elliptic, trigonous, ± constricted into a short stipitate base, usually the lignified style base persistent as short cylindrical remain. [details]

[details]Diagnosis This species is similar to C. phalaroides, from which it is mainly distinguished by its size. Carex via-montana exhibits smaller sizes of every structure, both vegetative and reproductive, when compared with individuals of C. phalaroides. Additionally, plants are frequently acaulescent or culms do not exceed 2 cm long. Moreover, the distribution of C. via-montana does not overlap with any other C. phalaroides group species nor does the habitat in which this species occurs. [details]
