Collinsonia
Collinsonia punctata Ell. was reported from CT by Dowhan (1979), presumably based on the following annotated sheet—31 Jul 1884, Woodward s.n. ( NCBS; image seen!). The specimen is C. canadensis, as evidenced by the smaller calyx and corolla (and as considered by the collector). Reference: Peirson et al. (2006).
