Notes: Although synonymized under Anerincleistus griffithii by J.F. Maxwell (Proc. Acad. Nat. Sci. Philadelphia 141: 29–72. 1989), A. pedunculatus is distinct from A. griffithii in leaf and stem pubescence and flower size, and the two species are easily distinguished in the herbarium and in the field (S.S. Renner, personal observation, 1992).
