11.  Viola lanceolata L. ssp. lanceolata N

lance-leaved violet. CT, MA, ME, NH, RI, VT. Sandy and/or peaty shorelines, borrow pits, open rights-of-way, ditches, and marshes.

5×11. Viola brittoniana × Viola lanceolata → This very rare violet hybrid is known from MA. It is relatively easy to distinguish due to the very different morphologies of the parental species. It is a relatively glabrous plant with cyanic corollas, short stolons later in the season, broad-lanceolate to narrow-ovate leaf blades that are lobed with an elongate central lobe and short lateral lobes (rather than triangular-ovate to suborbicular and with elongate lobes nearly as long as the entire blade in V. brittoniana).
