| Parrya arctica R. Br. | |
| Publ. & Syn. | R. Br., Chlor. Melvill.: 11 (1823). Type (BM): Canada: the Northwest Territories?, Melville Island [the Winter Harbour area], 1819-1820, leg. Capt. Parry (fruiting specimen), J. Ross (flowering specimen). |
| Notes | Mulligan: A record from Herschel Island in the northern Yukon Territory (Cody 1996) is based on material re-identified as Noccaea arctica. Elven and Murray: The distinction between Parrya arctica and P. nudicaulis is not very strong (see above). Parrya arctica is mainly characterized by narrowly obovate-spathulate and subentire leaves, by being completely glabrous, short sepals (max. 4.0 mm), small petals (max. 8 x 3 mm), and short anthers (max. 1.2 mm), and by fruits more or less erect and not constricted (torulose) or sinuous between the seeds. The majority, if not all, of these characters overlap with P. nudicaulis subsp. septentrionalis. |
