The Black lily (Fritillaria camschatcensis) is a rare species in the British Columbia Lower Mainland. It is an esturary plant which occurs, as far as I know, in 3 or 4 other sites near Vancouver, but this population may be the largest of them. The other 2 sites I have visited - in Port Moody and West Vancouver had fewer plants at the times that I looked at them, and occupied a smaller area.
The Henderson’s checker-mallow (Sidalcea hendersonii) is listed in The Rare Vascular Plants of British Columbia, by the National Museums of Canada. In this work it is rated as R2 - the second highest level of rarity on a scale of 1 to 4.
The Cuckoo plant (Cardamine pratensis) is also an interesting find. It occurs sporadically along the lower Fraser River, although none of the floras show it being this far south.
Finn Slough is occupied by a rich covering of estuarine plants, and there are dense populations of the estuarine Lyngby’s sedge (Carex lyngbyei) on the south shore of Gilmore Island.
