GENUS CODE: LOBEL
GENUS SCIENTIFIC: Lobelia
GENUS AUTHORITY: L.
GENUS COMMON: Lobelia
GENUS SUMMARY: (contributed by D.D. Spaulding, T.W. Barger, and B.A. Sorrie)
GENUS IDENTIFICATION: Identification notes: Vegetative Lobelia can be recognized by their milky sap, and the alternate leaves with obscure, whitish, callus-tipped, and often irregular or divergent teeth.
GENUS REFERENCES: Spaulding & Barger (in prep.)=X; Rosatti (1986)=Z; McVaugh (1936)=Y; Thompson & Lammers (1997); Lammers in Kadereit & Jeffrey (2007). Key based in part on X, Y, and GW.

FAMILY INDEX

FAMILY CODE: CAMPAN
FAMILY SCIENTIFIC: Campanulaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Bellflower Family
FAMILY SUMMARY: A family of about 80-82 genera and 2000-2400 species, mostly herbs, cosmopolitan. There is controversy about the circumscription of the family, specifically whether subfamily Lobelioideae should be recognized at the family level. Recent phylogenetic studies of the Campanuloideae also suggest that substantial rearrangements of generic boundaries will be needed (Crowl et al. 2014).
