The specimens in the clump with the narrowest and widest leaves are each circled with a blue and purple line, respectively. The width of the narrower two leaves are ~ 1 cm and ~ >= 1.25 cm (the "40" and "42" markings on the walking pole are 2 cm apart) and the width of the widest one is between 5 and 6 cm (I oddly didn't measure the latter specimen's widest leaf). Both specimens are developing scapes, and not just the one with the wider leaves.
This clump was part of a larger one that was disturbed by a tractor running over it since my last observation of a now-destroyed portion of it in late April and early May. See: https://www.inaturalist.ca/observations/75208511 ; and https://www.inaturalist.ca/observations/77440559 .
