Ultramafic outcrop near treeline
31726 VT, WTU
near plants of Polystichum lonchitis, P. lemmonii, P. kruckebergii
David Barrington (VT) writes 8 Jan 2024:
So, to get the crux of the matter your numbers 31726 and 31733 are confirmed as hybrids given on my study of the spores... 31726 also has irregular spores, but not many. So many of the sporangia remain unopened, though fully mature, and largely without contents except for what I Take to be a negligible amount of orphaned perispore clinging to the inside wall of the sporangium
These two do fall between the collections you sent of Polystichum lonchitis and P. kruckebergii morphologically. The character I found most useful was the ratio of the length to the maximum width for the medial pinnae—roughly 1:1 in P. lemmonii, 3:1 in P. lonchitis, and (though more variable) around 2:1 in P. kruckebergii. The two hybrids come in around 3:2.

growing on the top of the bluff edge
This is Trillium stenosepalum, the Rocky Mountain trillium, recently elevated to species status. Waiting for the name to become available in iNat. See https://doi.org/10.3120/0024-9637-70.3.158
Probably braunii, but indusia entire. Many plants in talus under sitka alders. None of the plants showing bulbils on rachis.
2 plants with P. munitum and P. braunii (?). Pinnules not free along base, bulbil on outer rachis.
North-facing cliffs above Whipple wash, volcanics. Restricted to bases of the most shaded cliffs here. ~350m.
Seems to be a new population.
Approx. location.
Growing in a dried up ephemeral pool 10m above tide line.
Three Mile Prairie County Park, sandy substrate of seasonal pond after it has begun to dry up.
doesn't look quite like r. sitchensis but I am stumped on what it might be
Will try to add flower pictures later; rocky area under Douglas-fir and manzanita, with Sanicula, Erythronium, Toxicoscordion, Paxistima
Common on small rock outcrops. Only known location in the province.
Matches location and description of herbarium specimen collected in 2015.
