Carex viridula featured on the right. This photo is a convenient comparison of three members of section Ceratocystis, all growing in association with one another on the mineral sand shorelines of an alkaline lake. Carex cryptolepis is in the middle; C. flava on the left.

Frequent on xeric conglomerate outcrops, densely cespitose. albicans/emmonsii-ish but need to look closer at specimens, would be weird habitat for albicans.

- floral: larger involucres, strongly recurved phyllaries
S. shortii

聯毛紫菀屬 (屬 Symphyotrichum)觀察者
vvoelker描述
Live specimen collected from mapped location on 6/30/2022. Apart from marginal cilia, whole plant is glabrous. Original stem and leaves shown in first two photos, lowest leaves are somewhat shallowly cordate and less sharply serrate than typical cordifolium, this was consistent across numerous plants of this type that we saw in the area. The plant then put out a second stem after a few weeks in potting soil on my back deck; lowest leaves of the new stem were long petiolate but not particularly cordate at all, and mid stem petioles were much more winged.
Thought it might be urophyllum when I collected it, but it's currently in bloom and the ray petals and phyllaries are distinctly cordifolium-like.

Capsules clustered though apparently cleistogamous flowers of C. canadense can cluster. Not evidenced with a photo but stems were solitary and arising from what looked like deeply set creeping rhizomes. Will need to revisit this summer
