Found along a gravel bar
Northern Green Bog-Orchid Platanthera aquilonis
Had flat, disk-shaped eggshell white seeds
Schweinitz's Umbrella Sedge or Sand Nut-Grass Cyperus schweinitzii
Growing in a recently bulldozed, empty lot
A.E. Wilson Park, Regina, Saskatchewan
idk who this is crawling across the grass in my neighborhood but i love them
Many large individuals of this species here
on undeveloped urban residential lot

Ternate leaves, 3 teeth only per side, cut ~1/2 to midvein, widely spaced teeth; leaflets not strongly overlapping.
Flower bractlets ~1/2 as wide as sepals with edges rolled down.
Single flowers.
Leaf and stem hairs:
P. subvahliana - "long hairs common to abundant, spreading to ascending, 1(–2) mm, ± weak, rarely stiff, smooth, crisped/short-cottony hairs usually absent, sometimes sparse"; leaves - "abaxial grayish or yellowish white, long hairs 0.5–1 mm, cottony-crisped hairs ± dense (often obscured by long hairs), adaxial dark green to greenish gray, long hairs ± abundant, other hairs absent." (F of NA).
P. subgorodkovii - "long hairs common to dense, ± ascending to loosely appressed, sometimes spreading, 1–2 mm, ± soft, smooth, crisped/short-cottony hairs usually sparse, sometimes absent or common"; leaves - "abaxial yellowish or grayish white to white, long hairs 0.8–1.5 mm, cottony-crisped hairs ± dense, adaxial green to grayish green, long hairs sparse to ± abundant, other hairs usually absent. " (F of NA).
I can't tell the difference based on the F of NA descriptions above (sounds like both are saying the same thing without clear distinction).
If I go to Vascular Flora of AB (Kershaw & Allen):
P. subvahliana: "Leaf stalk hairs long, weak (rarely stiff) plus 0-few crinkly/cottony hairs".
P. subgorodkovii: "Leaf stalk hairs crinkly/cottony and (usually) long, soft.
The leaf undersides on this plant show what I'd think of as "cottony" hairs. Based on that, I'd think of these stem hairs as long, soft/weak and lacking crinkly/cottony hairs?
So... P. subvahliana?

The leaf undersides on this plant show what I'd think of as "cottony" hairs. . As compared to https://inaturalist.ca/observations/150680232, these stem hairs do seem crinkly and long (but not cottony)?
So... P. subgorodkovii?
(Are they even different??)
Large thorns. This site is an abandoned campground and with lots of urban invasives, could this be a non-native hawthorn (Crataegus)?
