Kalm's Lobelia - Lobelia kalmii
State Rank Reason (see State Rank above)
Lobelia kalmii occurs in fens and other high-organic wetlands in northwest, central, and northeast Montana. Approximately 34 observations have been made at about 23 unique locations. The central Montana location has not been observed since 1934. Current observation, population size, and threat information at documented sites is needed.

General Description
Stems erect, usually simple, 10–40 cm. Herbage glabrate. Basal leaves petiolate, spatulate, entire to obscurely dentate, 1–3 cm long. Stem leaves becoming linear-lanceolate, 1–4 cm long. Inflorescence of <10 flowers; pedicels bracteate. Flowers: sepals lanceolate, 2–3 mm long; corolla 5–10 mm long, blue, whitish at top of the tube. Capsule obconic, 4–7mm long (
Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
Lobelia is named for the botanist Mathias de L'Obel (Morley 1970). In 1570, Mathias along with Pierre Pena published the first book that arranged plants by leaf characteristics, which represented a major advancement in the study of plant classification (Morley 1970).
Diagnostic Characteristics
Plants slender rarely over 4 dm tall, flowers 7-16 mm long, pedicels with a pair of subopposite bractioles; corolla not normally fenestrate, base of lower lip smooth; capsule ovoid, seeds rough tuberculate.
