..........6 Inflorescence a raceme (sometimes leafy, the flowers therefore essentially axillary); flowers mostly on short pedicels < 5 mm long (or to considerably longer in C. persicifolia); [exotic species usually of disturbed areas]. |

............ ....9 Ovary hairy with spreading or retrorse hairs; stem leaves (at least the lower) distinctly petioled. |
............ ......10 Flowers nodding; calyx lobes spreading to strongly reflexed at maturity |
............ ......10 Flowers erect to spreading; calyx lobes erect, more-or-less appressed (including at maturity) |

1 Corollas radially symmetrical (actinomorphic); carpels (2-) 3-5; [subfamily Campanuloideae]. |
..2 Capsule dehiscent apically; flowers solitary or in very diffuse panicles ( Platycodon, Wahlenbergia), or in compact involucrate umbels ( Jasione); [exotics, generally in weedy or disturbed situations]. |
....3 Flowers and fruits borne in an involucrate umbel |
....3 Flowers and fruits solitary or in a diffuse inflorescence. |
......4 Flowers large, 1 to few, solitary or nearly so; leaves large, ovate to elliptic; [Platycodonoid clade] |
......4 Flowers small, several to many, borne in a diffuse inflorescence; leaves small, linear to narrowly elliptic; [Wahlenbergioid clade] |
..2 Capsule dehiscent laterally (the pores nearly apical in some Campanula); flowers in spikes, racemes, or panicles; [mostly native species of various habitats (some of them weedy)]. |
........5 Inflorescence spicate, the flowers sessile, mostly in the axils of well-developed leaves; corollas rotate and style straight. |
..........6 Stamen filaments glabrous; stem branching; flowers all chasmogamous |
..........6 Stamen filaments hairy towards the base; stem strict, unbranched; flowers chasmogamous, but often with the lowest flowers cleistogamous |
