Annual to perennial herb [ tree].
Leaf: generally cauline, generally simple, generally alternate, petioled or not; stipules 0.
Inflorescence: cyme, panicle, raceme, spike, or flowers 1; terminal or in axils of leaf-like or reduced bracts.
Flower: bisexual, cleistogamous or open, radial or bilateral, inverted ( pedicel twisted 180°) or not; hypanthium generally present, ± fused to ovary; sepals generally 5; corolla radial to 2-lipped, petals generally fused, tube deeply divided on 1 side or not, lobes generally 5; stamens 5, free or ± fused ( anthers, filaments fused into tube or filaments fused above middle); ovary inferior or 1/2 inferior (superior in fruit), chambers 1–3, placentas axile or parietal, ovules many, style generally 1, 2–5-branched.
Fruit: generally capsule, open on sides or top by pores or short valves.
± 90 genera, ± 2500 species: worldwide. [Haberle et al. 2008 J Molec Evol 66:350–361] Some cultivated for ornamental (Campanula, Jasione, Lobelia). Subfamilies sometimes treated as families. Positions of flower parts given after flowering inversion, if any. Parishella moved to Nemacladus. —Scientific Editor: Thomas J. Rosatti.

Stem: decumbent to erect, (10)20–40 cm.
Leaf: cauline, often deciduous before flower, 0.5–2(4) mm wide, lanceolate to awl-like (uppermost wider or not), sessile, generally entire.
Inflorescence: spike; terminal flowers often aborted, overtopped by fertile; pedicels 0.
Flower: bilateral, generally inverted at full bloom by twisted ovary; corolla generally >> calyx, blue to pink or white, generally with a symmetric white or yellow spot on lower lip, tube entire, limb strongly 2-lipped, upper lip lobes 2, lower lip generally with 2 low ridges, these often with 2 knob-like projections near throat, lobes 3, > upper, generally obovate, obtuse- mucronate; stamens fused ( filaments, anthers in tubes), generally 2 smallest anthers each with terminal tuft of bristles, 1 bristle triangular or horn-like, generally 0.2–0.5 mm, others linear, shorter; ovary inferior, long, narrow, ± pedicel-like, chambers 1–2, placentas parietal or axile.
Fruit: dehiscent on sides by 3–5 sometimes translucent slits, tardily so or not.
15 species: w North America, Chile. (A.J. Downing, Am horticulturist, 1815–1852) [Schultheis 2001 Syst Bot 26:603–621] Fl part positions ("upper" is adaxial; "lower" is abaxial) given at full bloom. Corolla measurements are from base of tube to tip of longest lobe, color included albino for ± all species. Based on geog, interfertility, cytology, and sequences of nuclear as well as chloroplast DNA, Downingia yina Applegate (as recognized in TJM (1993)) split here into 3 morphologically indistinguishable species whose limits need further study, only 2 of which are documented for CA: Downingia pulcherrima, Downingia willamettensis.

Unabridged note: Fl part positions ("upper" is next to stem; "lower" is away from stem) given at full bloom. Corolla measurements are from base of tube to tip of longest lobe, color included albino for ± all species. Based on geog, interfertility, cytology, and sequences of nuclear as well as chloroplast DNA, Downingia yina (as recognized in TJM (1993)) split here into 3 morphologically indistinguishable species whose limits need further study: Downingia yina (as now circumscribed, not in CA, although possibly in – yet not documented for – n CaR), Downingia pulcherrima, and Downingia willamettensis. The present treatment comes after Downingia pulcherrima and Downingia willamettensis had been united under Downingia willamettensis, and that taxon in turn had been transferred to Downingia yina, as Downingia yina var. major (leaving the remainder of that sp. under Downingia yina var. yina).
Flower: corolla (7)8–13 mm, lateral sinuses ± = upper, sinus between 2 upper lobes with a backward-projecting horn, lower lip lavender-blue with central white area including 2 yellow and 2–4 purple spots near throat; anthers < 45° to filaments; ovary minutely spiny- to papillate-scabrous, 2-chambered, placentas axile.
Fruit: 25–65 mm, not easily ruptured even when dry, lateral walls tough, lines not translucent.
Seed: with longitudinal lines.
