Herbs annual, subshrubs, or shrubs, glabrous, pilose, hispid, or papillate. Leaves alternate, rarely opposite, sessile, terete or semiterete, rarely linear, base usually expanded, sometimes decurrent, apex obtuse or with an acicular awn. Flowers bisexual, solitary or glomerulate in bract axils, forming a spicate or paniculate inflorescence on upper part of branches; bracts ovate or broadly lanceolate; bractlets 2. Perianth 5-parted; segments ovate-lanceolate or oblong, adaxially concave, membranous, becoming hardened later, glabrous or pilose, with a transverse, winglike appendage near middle abaxially; distal portion of segments incurved, apices usually connivent, together embracing utricle and appearing conic; abaxial appendage spreading, membranous in fruit, sometimes undeveloped and appearing crestlike or tuberculate. Stamens 5; filaments subulate or narrowly linear, flattened; anthers oblong, apex appendaged, appendage apex acute or obtuse, variously shaped, or very small. Ovary broadly ovoid or globose, depressed; style long or very short; stigmas 2, erect or recurved, subulate or filiform, adaxially papillate. Fruit a utricle, globose; pericarp membranous or fleshy. Seed horizontal, vertical, or oblique; embryo spiral; perisperm absent.
Herbs, annual, or subshrubs [shrubs and small trees] , glabrous, or ± pubescent or hispid. Stems erect, ascending, or prostrate, branched (rarely simple), not jointed, not armed, not fleshy. Leaves mostly alternate (rarely opposite, especially proximal ones), sessile; blade lanceolate, linear, or filiform to subulate, semiterete, margins entire basally, apex obtuse, soft and subspinescent or narrowed to spine or soft bristle. Inflorescences spicate, flowers solitary in axils of bracts or reduced distal leaves (rarely 2-3-flowered with lateral flowers poorly developed); bracts ovate-lanceolate, spine-tipped. Flowers bisexual, with 2 bracteoles; perianth segments persistent, 5, covering utricle at maturity, often developing transverse, dorsal, membranous or ± coriaceous wing (sometimes only 2-3 segments winged, sometimes wingless or nearly so); stamens 5; styles and stigmas 2 (or 3). Fruits utricles, covered by perianth segments at maturity; pericarp adherent. Seeds usually horizontal, orbicular; seed coat black or brown; perisperm absent. x = 9.
"Fls perfect; cal deeply 5-lobed, the segments at maturity incurved over the fr, transversely carinate or winged, the tips connivent and erect; stamens usually 5; styles 2; seed thick, horizontal; embryo spirally coiled; perisperm none; ours branching, annual herbs with linear, succulent, ± spinulose-tipped lvs, the fls solitary or few in the axils of the shorter and spinier upper lvs (bracts), each subtended by a pair of bracteoles. 50+, widespread."
Seeds normally “horizontal”(i.e. vertically compressed); testa membranous.
Fruit with membranous or somewhat fleshy pericarp.
Annual or more often perennial herbs or shrubs, usually pubescent.
Leaves usually more or less fleshy, entire, alternate or sometimes opposite, sessile, narrow, often scale-like, sometimes linear-subulate.
Flowers axillary, solitary or fascicled, sometimes aggregated in a spiciform way towards ends of branchlets, subtended by two relatively large bracteoles, hermaphrodite.
Perianth (4) 5-partite, the lobes nearly always each developing in fruit above the middle a scarious horizontally spreading wing.
