New Records
This page will show new species and significant records that should be added to the current checklist (dated January 2016). Shown below will be:
  • records that are new species for the checklist
  • reports of species previously known only from historical records (30 years old or more)
  • records of species listed only in Appendix 1 (Excluded Species and Unconfirmed Reports)
When a sufficient number of new records and other changes accumulate, the checklist will be revised and a new version made available on the Download Plant List page. Until that time, here are the new records. As in the checklist, a species preceded by an asterisk (*) is non-native in the county.

Thalictrum venulosum Trel. (Veiny Meadow-rue) -- previously known only from a 1922 record from Carleton Place (probably along the Mississippi River). A small colony was found by Graham Page at Blakeney Rapids on  the Mississippi on 10 July 2016.

Persicaria arifolia (L.) Haralds. (Halberd-leaved Tear-thumb) -- Mike Oldham of NHIC reported that this species was found in September 2018 in Wolf Grove, west of Almonte, by Michael Patrikeev. Mike Oldham confirmed the identity of a specimen that will be donated to CAN (the herbarium of the Canadian Museum of Nature). Halberd-leaved Tear-thumb is provincially significant (S3).

Polygala sanguinea L. (Purple Milkwort) -- previously known only from an extirpated 1990 record near Watsons Corners. A patch of a few dozen plants was found by Ken Alison at the Perth Wildlife Reserve Conservation Area on 3 August 2019. Purple Milkwort is provincially significant (S3).

Hypericum punctatum Lam. (Spotted St. John's-wort) -- previously known only from a 1986 sight record from the California area by Patsie Rothschild. Never having seen the species in the county before, the present author was very surprised on 6 August 2019 to find a large colony about 100m from his house!
