Notes

Notes: While Colwell et al. (2017) include May in the flowering time, no May records were found.
Threats: Potentially threatened by improper burning regime.
Taxonomy: Previously identified as either A. fasciculatum or (sometimes) A. purpureum; differentiated by its growth on Galium and the presence of 2-4 yellow flowers per stem with pedicels longer than the stem. Differentiated from A. epigalium ssp. epigalium by its paler, straw-colored flowers and shorter corollas with more prominently arched tubes, +/- horizontal mouths, and narrower lobes with erect or weakly recurved tips.
