34. Carex oligocarya C. B. Clarke, Fl. Brit. India. 6: 746. 1894; R.R.Stewart, l.c. 81; Kukkonen in Rech.f., Fl. Iranica, tab. 36, fig. 3. 1998.

C. oligocarya C.B. Clarke var. websteri Raymond, in Webster & Nasir in Pak. J. For. 15(3): 218. 1965; C. annulata Kük., in Engler, Pflanzenr. IV.20, 38: 494. 1909, nom. nov. for C. oligocarpa C.B. Clarke 1898; (for orthography see also Kew Bull., Misc. Inf., Add. Ser. 8: 149 1908).

Loosely tufted, 25-40 cm. Rhizome ascending, covered by grey-brown, finally fibrous scales. Stem obtusely trigonous, grey-green, smooth. Leaves c. 2/3 of stem length; sheaths 20-30 mm, yllowish brown to grey, finally slightly fibrous, margin of scarious side slightly concave; ligule c. 0.2 mm; blades 2.5-3 mm wide, keeled, flat or slightly revolute, long-attenuate, keel and margins scabrous. Inflorescence of 2-4 spikes, all androgynous, large in upper, predominantly male part, in lower part lax. Bracts shorter than their spikes, lowest with sheath to 18 mm. Spikes 10-20 mm, cylindrical or fusiform, lowest with peduncle to 80 mm. Male glumes 3.5-4.5 x 0.8-1 mm, narrowly elliptic, acute or with mucro up to 0.2 mm, margins widely scarious. Female glumes 3.7-3.8 x 1.5-1.6 mm, acute or with up to 0.3 mm mucro, margins widely scarious. Utricles 4.7-5.1 x c. 1.3 mm, obovoid, trigonous, slightly inflated, yellowish brown, abruptly contracted to beak, 1.6-2 mm, lower part setose, ostiole oblique with wide scarious margins. Stigmas 3. Nut 2.3-2.8 x 1-1.3 mm, obovoid, trigonous, yellowish, obscurely reticulate.

Fl. Per.: July.

Syntypes: Kashmir, ”Dras to the Karakorum, alt. 12-13000 ft”, C.B. Clarke 30436! 30533! (K); both infected by Anthracoidea.

On steep alpine slopes; Distribution: W. Himalayas.

As utricles of both syntype specimens of C. oligocarya are infected by an Anthracoidea smut species, it is evident that further study is required.
