Annual, perennial herb [shrub, tree, vine]. Stem: generally erect [climbing], branched, glabrous to hairy. Leaf: cauline, alternate to opposite or whorled, simple, generally sessile, linear to obovate, entire to minutely toothed or ciliate, teeth occasionally gland-tipped; stipules small, dark-colored, spheric glands, or 0. Inflorescence: raceme, panicle, or cyme [spike]. Flower: bisexual, radial; sepals 5, free; petals = sepals in number, free to adherent; stamens 5[4 or 10], alternate petals, filaments fused basally into a cup-like structure surrounding ovary base; staminodes present, alt stamens at cup rim, or 0; ovary superior, carpels 2–5, fused, styles 2–5, = carpel number, free or partly fused. Fruit: capsule, generally dehiscent [drupe in some tropical species], generally 10-seeded.
13 genera, ± 250 species: cosmopolitan, most temperate, some cultivated. [McDill et al. 2009 Syst Bot 34:386–405] Hesperolinon, Sclerolinon are evolutionary lineages within Linum. —Scientific Editors: Douglas H. Goldman, Robert Patterson, Bruce G. Baldwin.

Key to Linaceae
1 sp. (Greek, Latin: hard flax, for hard, generally indehiscent fruit) [Rogers 1966 Madroño 18:181–184] Closely related to Hesperolinon.
Annual. Stem: erect, glabrous. Leaf: opposite, 5–16 mm, oblong to elliptic, proximal generally entire, distal generally serrate; stipule glands 0. Inflorescence: cyme; bracts generally serrate. Flower: sepals unequal, margins gland-toothed; petals 5, yellow, appendages 0; staminodes 0; carpels 2, ovary chambers 4, styles 2, free, ± 1 mm; stigma > style in width, head-like. Fruit: capsule surface rough; indehiscent or breaking into 4 closed, 1-seeded segments in age. Seed: ± 1 mm, ± 3-sided in ×-section, tip acute.
Generally vernally moist meadows; 1000–1800 m. Klamath Ranges, Cascade Range, Sierra Nevada; to Washington, Idaho. Jun–Aug [Online Interchange]
