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
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!
Helenium autumnale L. (Sneezeweed) -- found by Cathy Keddy in August 2019 at the edge of a beaver pond in the High Lonesome Nature Reserve in the Pakenham Mtns. According to Cathy, Eleanor Thomson found Sneezeweed in this area in 2012.
