Calamagrostis pickeringii — Pickering's reedgrass
Endangered — In 2013 we documented a few three and three more locations for Calamagrostis pickeringii in addition to those found in 2012. For our state, this is a northern species historically known from the hills of northern (Middlesex and Essex) counties; yet all currently found subpopulations in Massachusetts are restricted to the pine barrens area in the southeast (Plymouth), apparently associated here with frost pockets and constituting parts of a single large population. We observed a few specimens in comparatively warmer and drier situations: on pocket slopes or ridges between adjacent pockets, yet invariably not far from larger (source) colonies situated around small ponds or at wet bottoms of frost pockets. In one case a subpopulation was found at a relatively dry bottom of a frost pocket.

Watch listed — Maybe a new town record (Plymouth)
Linnaea borealis — twinflower
Watch-listed. The only image we can provide from eastern MA is that of a plant cultivated at the South Shore Natural Science Center in Norwell. We used this photo for our Plant of the Month story in May 2013 Starflower Puzzles, though have not included it in the photo gallery. The species is known to be native in 9 counties including Norfolk, Plymouth, and Barnstable, yet it is likely to be extinct here. Even in Worcester County it appears to be declining, currently found only in three northernmost towns (Bertin and Rawinski 2012).
Froelichia gracilis — slender cottonweed
This plant is native in North America from Iowa and Colorado to Texas and Mexico. In Massachusetts it is rapidly expanding, apparently along highways and other roads. As per Massachusetts County Checklist of 1999, at the time it was recorded only from 5 western counties (from the Connecticut Valley to Middlsex Co.). We first found it in eastern MA in 2008 in Myles Standish State Forest (Plymouth Co.), during a survey at the detention facility in the middle of the Forest; then in 2011 along Rt. 151 in Falmouth (Barnstable Co.); and in 2012, as a nearly continuous stretch along Rt. 3, embracing at least 4 adjacent towns: Pembroke, Norwell, Hanover, and Hingham (Plymouth Co.) as well as along Rt. 93 in Milton/Quincy (Norfolk Co.). In 2013 we collected and photographed cottonweed at Rt. 24 within the Blue Hills Reservation in Randolph (Norfolk Co.) and also along Rt. 225 (Carlisle Rd.) in Bedford (Middlesex Co.).
Pedicularis canadensis — wood betony
This plant deserves at least a watch-listed status. It is marked "uncommon" in the Flora of Worcester County by R. Bertin and T. Rawinsky (many historic locations, but only 7 current). In eastern MA, we've encountered it only twice during more than 10 years: once in Stony Brook Res., Boston in 2005 (and that clump appears to be gone now) and another small clump in Nasketucket Bay State Res., Mattapoisett, in 2013 (we have doubts if it is indigenous and not introduced with a sowing mix, because there was an entire constellation of unusual plants).
