Prof. Sargent has been over the route taken by Michaux in 1788-89, chiefly to try to find the original localities for Magnolia cordata, which Michaux is believed to have ardently searched for. But Prof. Sargent now believes that botanist was looking for Magnolia Fra-seri. But so far as Magnolia cordata is concerned, Prof. Sargent could not find plants like the one known as such in gardens, and he is inclined to believe that it is only an extreme form of the common cucumber magnolia, M. acuminata.
