State Rank Reason (see State Rank above)
Lonicera caerula variety cauriana occurs in southwest Montana where it seems well represented. It grows in wet meadows, fens, and other wetlands at moderate to high elevations. Populations appear to be stable, growing in habitats with few to no threats. Current data on locations, population sizes, and threats is needed.

Shrubs. Stems erect, branched 20–80 cm; twigs sparsely villous. Leaf blades oblanceolate to obovate, 2–7 cm long, rounded at the tip, sparsely villous beneath. Inflorescence: peduncles 2–8 mm long; lower 2 bracts linear, green; upper bracts brown, enclosing the ovaries. Flowers: corolla yellow, 9–13 mm long, glabrate; lobes about as long as the tube. Berry red (glaucous-blue), about 1 cm long, born in the cup formed by the bracts (Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX
