Information stem shorter and less branched than in the type, 1 lin. in diam.; leaves three times wider. null

Information Rootstock woody. Stems erect, puberulous, reddish and woody below, slender. Leaves linear, 1 in. long, 1 lin. wide or less, almost glabrous; setæ longer than the tubular part of the ochreæ. Bracts with about 2 setæ besides the terminal cusp.

Information Herbaceous. Stem erect or ascending, up to 3 ft. high; branches slender, more or less distinctly triquetrous, papillose. Leaves from linear to lanceolate, 1–2 in. long, 1–3 lin. wide, acuminate, sometimes trifid, pubescent; ochreæ 3 lin. long, tubular, pubescent, setæ about 10, pallid, shorter than the tubular part. Racemes terminal, lax, slender, up to 6 in. long; bracts oblique, subulate, not setose, pubescent; pedicels 2–4 in the axil of each bract, shortly exserted. Perianth nearly 3 lin. long, cylindrical and densely pubescent below, campanulate and less densely so above; lobes twice as long as the tube, oblong, acute. Stamens half as long as the perianth; anther-cells diverging at the base. Fruit triquetrous, acuminate, not winged nor spiny.

Information An erect herb with thick, woody, gnarled, reddish-brown, perennial stems 1 cm. or more thick; and with annual shoots, green becoming red below, puberulous to thickly pubescent, 20–40 cm. tall, strictly erect or diffuse, 3–4 mm. thick. Ocreae 3–7 mm. long, pubescent, truncate, terminally membranous and fringed with reddish-brown, bristly setae 6–8 mm. long; the leaf inserted in the upper half but often as much as 3 mm. from the apex. Leaves sessile, erect-patent, linear to narrowly elliptic-lanceolate, 20–30 × 1–6 (–10) mm., glabrous to thickly pubescent, terminating in a readily deciduous awn 1–2 mm. long. Inflorescence slender, moderately elongated, up to 20 cm. long, the stalk glabrous to thickly pubescent. Bracts 3–4 mm. long, pubescent or glabrous; terminally membranous or mainly so, truncate but dorsally produced and narrowed into a bristly, pubescent seta 3–4 mm. long with or without 1–2 lateral setae. Pedicels glabrous or pubescent with white hairs, exceeding the bracts by 2–4 mm.; those of ♂ flowers withering; those of hermaphrodite flowers lengthening and thickening. Flowers 1–3 to each bract. Tepals white, 3–4 mm. long, oblong-linear to elliptic-lanceolate. Anthers blue or bluish. Styles of short-styled flowers 1 mm. long; of long-styled flowers 3–5 mm. long, connate for ⅔ their length. Fruit pubescent, 6 mm. long, bluntly trigonous, lanceolate-ampulliform, broadest below the middle, unarmed, with 2–3 longitudinal ridges down each face and with transverse ridges when ripe. Fig. 5/79, p. 29.

Information An erect or ascending herb. Stems up to 1 m. tall, glabrous to pubescent, reddish-brown. Ocreae 4–6 mm. long, pubescent, membranous, truncate, with a terminal fringe of ± light-brown, erect-patent setae 4–5 mm. long. Leaves 2–8 cm. long, often less than 8 mm. broad but up to 1.8 cm., basally decurrent, narrowly elliptic-lanceolate or linear-lanceolate to lanceolate or lanceolate-elliptic, apically acute, mucronate, entire, the margins sinuous, or with 1–3 pairs of forward-directed lobes, sometimes very asymmetrical, puberulent or not on the midrib. Inflorescence elongated, probably up to 30 cm. Bracts 4 mm. long, 1–2.5 (–3) cm. apart, pubescent, with or (commonly) without a fringe of setae. Pedicels 2–4 (–6) together, not exceeding the bracts by more than 3 mm., erect, glabrous or puberulous. Flowers white, 4.75–6 mm. long. Tepals 3–3.75 mm. long. Short styles probably 1.5–2.5 mm. long, free to the base or up to 1 mm. connate. Filaments 1–4.5 mm. long. Fruit 5 (–6) mm. long, pubescent, otherwise smooth, conical, usually armed a little above the base with three small (sometimes scarcely perceptible) ± retrorse teeth or protuberances at the angles.
