Campanula
See list of 12 species in this genusPhylogenetic work using nr DNA suggests that the genus Campanula is not monophyletic (Eddie et al. 2003). Specifically, some bellflowers (e.g., C. aparinoides, C. carpatica, C. persicifolia, C. rotundifolia) may need to be segregated from the remainder of Campanula s.s. in order that recognized taxa be monophyletic. Campanula bononiensis L. was reported from ME by Magee and Ahles (1999), but the specimen was misidentified and is C. rapunculoides— Fernald 2139 ( NEBC!).
-
1a. Style conspicuously exserted from the corolla; corolla globose-campanulate
-
1b. Style included within the corolla to ± reaching the tips of the corolla lobes; corolla campanulate, tubular-campanulate, funnelform-campanulate, or rotate-campanulate
-
2a. Corolla 4–13 mm long; stems 3-angled, slender, weak, leaning on other vegetation [Fig. 533]
-
2b. Corolla 10–55 mm long; stems terete or obscurely angled, erect to ascending
-
3a. Calyx with an appendage between the lobes
-
4a. Corolla broad-campanulate, yellow-white, unspotted
-
4b. Corolla tubular-campanulate, usually white to light purple, usually spotted within
-
-
3b. Calyx without appendages between the lobes
-
5a. Flowers sessile in terminal and sometimes also axillary glomerules [Fig. 534]
-
5b. Flowers pedicellate, not arranged in compact clusters
-
6a. Calyx lobes linear; stem leaf blades linear to narrow-lanceolate
-
7a. Basal leaf blades obovate; capsules erect, dehiscing by lateral or subapical pores
-
7b. Basal leaf blades broad-ovate to cordate-orbicular; capsules nodding, dehiscing by basal pores
-
-
6b. Calyx lobes lanceolate to triangular or oblong; stem leaf blades lanceolate to ovate, cordate-ovate, or triangular-ovate (narrower in C. persicifolia)
-
8a. Stem leaf blades linear to narrow-lanceolate
-
8b. Stem leaf blades lanceolate to ovate, cordate-ovate, or triangular-ovate
-
9a. Corolla broadly rotate-campanulate; capsules dehiscing by subapical pores
-
9b. Corolla campanulate, funnelform-campanulate, or tubular-campanulate; capsules dehiscing by basal pores
-
10b. Calyx lobes erect during anthesis [Fig. 535]; inflorescence of solitary, axillary flowers or of non-secund racemes of 1–4 flowers at the apex of the stem and branches [Fig. 535]
-
11a. Stem sharply angled; lower leaf blades evidently cordate at the base; inflorescenc a loose raceme of 1–4 flowers at the apex of the stem and branches
-
11b. Stem bluntly angled; lower leaf blades rounded to cuneate at the base; inflorescence of solitary flowers in the axils of leaves, collectively appearing to be a terminal, leafy raceme [Fig. 535]
