Characteristics

Perennials, variable in size; when crushed emitting a pungent smell (like a Jerusalem Artichoke). Roots fibrous and with several larger contractile roots. Rhizome stoloniferous or cormous (when the stolons are arrested in hard soils), often forming cormlets, the fibrous covering hard and sclerotic in dry surroundings or soft or nearly absent in moist conditions. Leaves variable in size, 5-35 cm long and 0.5-2 mm broad, filiform to semi-terete, with a shallow ventral groove, gradually tapering to an acicular apex, expanded below to form an open, semi-amplexicaul sheath, glaucous, succulent; the primary leaves, if present, bract-like, scaly, brown. Inflorescence an erect central, few to many flowered raceme; scape terete, firm; pedicels patent to erocto-patent, decurrent, lengthening in fruit, 2-10 mm long; flowers green with the apiculate tips of the segments often purplish, segments conshiform, 2-3 mm long; stigmas 3, papollose, purple, sessile, 3 outer carpels vestigial, 76 mmner soon lengthening at anthesis and after fertilization. Follicles 5-10 mm long, narrowly ovoid-acuminate to cyndrical, tipped by the 3 persistent, hook-like style-bases, with a very short spur.
More
Perennial wetland herb. Rootstock bulbous, fibre-covered, bearing smaller bulbils. Leaves semi-terete, channelled above, tapered distally, to 30 cm long, to 3 mm diam.; basal sheath terminating in a 2-lobed ligule. Scape at fruiting terete, to 20 cm long. Infructescence an erect raceme, c. 10–13 cm long, with 27–35 fruits; pedicels slender, spreading, 3–8 mm long. Fruit narrowly ellipsoid-cylindric, attenuate distally with short stylar beaks outcurved at apex, c. 8–10 mm long, 1.5–2 mm diam. Carpels 6, fully united ventrally, 3 fertile alternating with 3 sterile, erect to spreading; fertile carpels smooth, lacking projections; sterile carpels forming a slender, 3-winged central axis.
Perennial herb, helophyte, 0.1-0.6 m high; rhizome stoloniferous or cormous, usually with cormlets. Leaves basal, usually distichous, ± terete, glaucous, with semi-amplexicaul sheaths. Scape erect, firm. Inflorescence an erect raceme; pedicels patent; flowers green; perianth segments with purplish apex; outer boat-shaped, acute; inner obtuse. Ovary: 3 vestigial outer carpels and 3 inner carpels lengthening at anthesis and after fertilization; stigmas 3, purple, papillose. Flowering time Sept.-June. Follicles elongate, with 3 fertile carpels and no sterile ones.
Tufted, bulbous perennial, 50-500 mm tall, with brown to dark brown fibrous tunics at base. Leaves green at flowering, narrowly cylindrical to filiform, ± as long as inflorescence. Flowers 4-50, in a dense or lax spike, green. Fruit narrowly ovoid, 4-10 mm long, without basal outgrowths.
Tufted perennial with fusiform bulbs, 5-50 cm, with dark fibres. Leaves green at flowering, terete to filiform. Flowers 4-40 in lax or dense racemes, green. Fruits narrowly ovoid, 4-12 mm long.
