A NORTHERN OCCURRENCE OF
DENTARIA MULTIFIDA MUHL.
By E. Lucy Braun
In the spring of 1913, the writer found a large patch of
Dentaria multifida Muhl. (Dentaria laciniala var. multifida
James) growing in a mixed beech woods near Madisonville,
a suburb of Cincinnati. This habitat has since been de-
stroyed, but plants from the original habitat are growing in
the Emery Bird Reserve, and in the writer’s garden.
This plant is not recorded, to my knowledge, as occurring
north of the northern boundary of Virginia and Tennessee,
and hence is not included in any of the texts dealing with
the floras of north-eastern North America. The plants were
compared, for verification of identification, with plants in
the Lloyd Herbarium, collected on Lookout Mountain,
Tenn., by Joseph F. James. The only difference noted is
that of size, the more northern plants being only about two-
thirds the height of those from Chattanooga.
Although James states (Bot. Gaz. 8:206, 1883 and Jour.
Cin. Soc. Nat. Hist. 7:67, 1884) that on Lookout Mountain
he found forms intermediate between D. laciniata and
D.	multifida, the plants found at Cincinnati were very
distinct, and no gradational forms were found.
In this latitude, the plants bloom from the middle to the
end of April—two to three weeks later than D. laciniata—
and the seeds ripen about the first of June. This is a very
beautiful plant, much more delicate and attractive than the
other species of Dentaria growing here.
