Sessileleaf Ticktrefoil is a prairie plant.  It’s been described as somewhat rare.  The only place I’ve seen it is in prairie restorations where it has be planted and is doing well.  Of course, I don’t get to pristine prairies much … there aren’t many in Indiana.

The peculiar thing about Ticktrefoils is their pod, which has it’s own word – loment.  A loment is a kind of pod that is pinched between each seed so that they can break apart easily.  The pod has little velcro-like hairs that help it stick to an animals fur. As the animal wanders around, the seed sections break apart and fall to the ground, thus dispersing the seeds.

Tick trefoils have unique pods.  They break apart into sections that each have one seed.  The pod has little velcro-like hairs that help it stick to an animals fur.  As the animal wanders around, the seed sections break apart and fall to the ground, thus dispersing the seeds.

Pods – “Loments”

This species is separated from other Ticktrefoils with long thin leaves by the fact that stem of the leaf is very short, almost missing.

Some pictures of the flowers show them to be much more sparsely situated along the stem than this.
