Iris setosa, Pall.
Iris setosa can be found throughout interior Alaska. These specimens from my neighborhood grew in disturbed soil along the roadside and bordering a spruce/hardwood forest. The plants can be very tall, up to a meter in height, with lanceolate leaves that have parallel venation and are alternately placed on the stem.
3 sepals (they look like petals!)
dry dehiscent locullicidal capsule
1 carpel (?I think)
# of seeds: a lot! at least 3 dozen
