Dear ID»*—Welch:

Thg’^yggs which you sefit is Setaria verticillata
(L.) Be&uw* It can easil^ be separated from other
species—ef S. by the retrorsely barbed bristles.

It is a queer coincidence that it should come up
with the Stenotaphrum which I gave you. It was
found here once, about 20 years ago, and I have
looked for it every year since then without suc-
cess. It is apparently spotted over the state,
and I note one record from your county. Deam
says that it is rather common around Bluffton,

I remember it as the commonest S. at Iowa City
the summer that I spent there. I imagine that; it
was brought into the greenhouse in the soil and
just happened to come up where it did.	___
