T: Morocco, Great Atlas, Zerekten, 1500–2000 m, J.Braun-Blanquet; holo: MPU, n.v. [In the Braun-Blanquet herbarium, MPU, no specimen with the above locality was located. The plant photographed in the protologue, deposited in MPU and labeled 'Gourdouze, 2000 m' thus may be a good candidate for a lectotype.]
Perennials 10–30 (–35) cm tall, caespitose, ciliate; rhizome short, vertical to oblique, some-times many-headed; stolons absent. Basal leaves usually 4–10 (–14) cm long, 2–4 (–5) mm wide; cauline leaves 1 (–2), usually 2–5 cm long. All leaves with long acuminate tip; margins papillose-serrulate. Lower bract ±herbaceous, sometimes ±membranous, shorter than inflorescence. Inflorescence decompound; main branches 3–8, smooth or sparsely papillose below clusters, thin, c. 0.2 mm in diam., often flexuose, patent to erect; secondary branches rare, with each branch bearing loose terminal (1–) 2–7-flowered glomeruliform clusters 4–5 mm in diam. Bracteoles ovate-lanceolate, subaristate, glabrous to sparsely ciliate, 1.5–2.0 mm long, membranous-scarious; midrib often castaneous-brown. Tepals ±equal, glabrous, entire or the inner ones minutely denticulate below apex, lanceolate to ovate-lanceolate, often almost entirely membranous with dark castaneous-brown midrib and short mucro, sometimes castaneous-brown with broad membranous margins, 1.9–2.6 mm long. Stamens 6; anthers c. 0.4 mm long, much shorter than filaments; filaments 0.8–0.9 mm long; style c. 0.2 mm long; stigmas 1.0–1.2 mm long. Capsule subglobular, ±obtuse, mucronate, castaneous-brown; capsule segments 1.7–2.0 mm long, including mucro 0.1–0.2 mm long and 1.4–1.5 mm wide. Seeds subglobular, pale castaneous-brown, smooth, shining, 0.8–0.9 (–1.0) mm long, 0.7–0.8 mm wide; apex pale; basal appendage indistinct, to 0.1 mm long, very sparsely fibrillate. 2n=12, fide N.Galland, Trav.
