One of the most interesting facts in botanical geography is the correspondence between the flora of the Eastern United States and that of China and Japan. New illustrations of this are being continually furnished. Every one knows the "May Apple," "Mandrake," or Podophyllum of our woods. One species, P. Emodi, has been discovered in Asia, and we have the further account from a correspondent of the Gardener's Chronicle :

"In the higher regions of the mountains a plant of great interest is found. This is a new species of Podophyllum, a plant of the same genus as that from which podophyllin, the principle of the celebrated podophyllin pills, is obtained. The natives attach great medicinal value to the plant, and probably with more reason than the value which is often ascribed by them to innumerable plants which they so freely use for all manner of complaints. Podophyllum peltatum, the source of podophyllin, is an American plant. A few years ago, Mr. Watters, H. M. Consul at Tamsui, in Formosa, discovered one, which Dr. Hance named P. pleianthum. The Lo-fau species is the second Asiatic one. Both of them are in cultivation here, now; two plants of the latter have just flowered for the first time in our Garden, where they have been growing for about two years. The larger one of the two has leaves two feet in diameter, and it is a striking and ornamental plant".
