Amsinckia douglasiana A. DC. has been erroneously attributed to Ma and Me due to misapplication of names (i.e., the name A. douglasiana was formerly misapplied to plants of A. menziesii var. intermedia) and misidentifications. This species has actually not been collected in New England. Amsinckia spectabilis Fisch. & C.A. Mey. var. spectabilis has been attributed to Middlesex County, MA, by several sources (e.g., Kartesz 1999, Sorrie and Somers 1999). The reports were based on the following specimen—1878, Alcott s.n. ( NEBC!). The specimen was incorrectly determined and is Amsinckia menziesii var. menziesii. Reference: Ganders (1993).
1b. Corolla tube open; anthers and style exserted beyond orifice of connate tube of corolla (but not exserted beyond lobes of corolla)
