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. Seed: many.
± 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.

Key to Campanulaceae
Annual, from taproot. Stem: prostrate, decumbent, or erect; base generally ± brown or ± purple; branches 0 or below middle. Leaf: basal; petiole short or 0. Inflorescence: ± raceme-like; bract 1 per flower, small; pedicel generally thread-like. Flower: inverted or not; sepals linear to triangular; corolla ± radial or 2-lipped, lobes 5; filaments free at base, fused into tube around style distally, appendages attached to a stalk or directly on 2 adjacent filaments, each with 2–12 cells, anthers free, all alike; ovary superior to 1/2 inferior, hemispheric to obconic, nectary glands 3, mounded or donut-like, on free part of ovary, stigma 2-lobed, papillate. Fruit: generally > hypanthium, hemispheric to fusiform, top pointed or rounded, chambers 2; open at top generally by 2 valves (or circumscissile). Seed: elliptic to oblong.Key to Nemacladus
18 species: southwestern United States, northwestern Mexico. (Greek: thread-like branch) [Morin 2008 J Bot Res Inst Texas 2:397–400] In descriptions, "filaments" including both free and fused parts thereof.

Unabridged note: Taxonomic changes from TJM (1993) based on ITS, atpB, morphology. Parishella californica nested within Nemacladus, in which it is here treated.
Erect, 8–18 cm, 1st branches generally 2–2.5 cm from base. Stem: ascending. Leaf: 6–18 mm, oblanceolate to elliptic, entire or obscurely toothed, hairy, narrowed to short, wide petiole. Inflorescence: axis strongly zigzag; bracts 1–3 mm, linear to lanceolate, spreading; pedicels 10–15 mm, 0.1 mm diam, ascending, generally straight, tip upturned. Flower: not inverted; hypanthium ± 1 mm; sepals ± 2 mm, triangular, erect; corolla conspicuously 2-lipped, divided ± to base, white, glabrous or ciliate, 3 adaxial lobes erect, 2 mm, yellow spot at base and 2 maroon arches above, 2 abaxial spreading, 3–4 mm, 2 maroon lines near base; filaments declined, ± 3 mm, tip ± curved, glabrous, appendage pad at base of filaments, cells obtuse, anthers ± 0.5 mm; ovary 1/2-inferior. Fruit: 2.5–3 mm, base acute, tip ± pointed. Seed: ± 1 mm, elliptic, with deeply impressed, vertical lines.
