This well-supported clade contains seven representatives of the Asian genus Adenophora (Asia), the
monotypic Hanabusaya of Korea, and six bellflowers, most of them occurring in China and surrounding areas. The whole assemblage is largely paraphyletic with an otherwise monophyletic Adenophora. Nonetheless, early study on Campanulaceae based on ITS sequence data (Eddie & al. 2003) inferred a paraphyletic Adenophora (11 species included) to Hanabusaya, a hypothesis in some way supported by morphological evidence. Indeed, both genera share campanulate flowers with very prominent nectaries, and nodding, basally opening capsules (Hong & Ge 2010). Our current sampling of Adenophora is somewhat limited, the genus containing some 67 species (Lammers 2007), and diverge qualitatively from the aforementioned study, thus precluding conclusive remarks on potential cases of incongruence between the respective maternally and bi-parentally inherited molecular markers. This well-resolved clade shows an early diverging lineage including Campanula aristata (Afghanistan to China) and C. crenulata (China), two high elevation plants occurring in alpine meadows or thickets. Morphologically, C. crenulata approaches C. delavayi, another Chinese species more frequent in pine forests, whose sister relationships with C. stevenii subsp. turczaninovii is poorly supported. The latter taxon mainly differs from other subspecies of C. stevenii by its chromosome number (2 n = 34 vs. 2 n = 32). Finally, both subspecies of C. lehmanniana (subsp. lehmanniana and subsp. pseudohissarica), from Kirgizstan and Tadzhikistan, are genetically similar, but their relationships with respect to other species of this clade remain poorly resolved.
