Any one familiar with the Bleeding-heart (B. eximia) of old-fashioned gardens, found growing wild in the Alleghanies, and with the exquisite White Mountain Fringe (Adlumia fungosa) often brought from the woods to be planted over shady trellises, or with the Dutchman's breeches, need not be told that the little squirrel corn is next of kin or far removed from the pink corydalis. It is not until we dig up the plant and look at its roots that we see why it received its name. A delicious perfume like hyacinths, only fainter and subtler, rises from the dainty blossoms.
