Dear Doctor Britton
I have recently received from Hamilton County, Ohio, speci
mens of a prickly lettuce which is evidently the Lactuca scariola illus
trated and described in Volume 3 of your Illustrated Flora. These
specimens and also one specimen in the National Herbarium, collected
by Sandberg and Leiberg in northern Idaho, constitute the only material
that I have seen from the United States of this form, having runcinate
pinnatifid leaves. The common form, of which I have received hundreds
of specimens from pearly all parts of the country, has in all cases
had entire leaves. The leaves of this common form are prickly on the
margins and in most cases on the back of the midrib, and are in nearly
all cases twisted so as to stand on the same vertical plane on the north
and south sides of the plant, and with their margins up and down. The
specimens from Ohio came partly pressed, so that I was unable to deter
mine with certainty the original position of the leaves, but I do not
think that they were twisted and arranged in a vertical position to
