ceum, of which, perhaps, it is only a variety; we have called it D. Japonicum, Fr. and Sav.;—The Ilysanthes saginoides, Fr. and Sav., a small species from Niko, having the appearance of a Sagina, and very different on this account from other species of the same genus:—The Veronica Yedoensis, Fr. and Sav., which must be placed by the side of the V. acinifolia.
Labiateæ. Plectranthus caudatus, Fr. and Sav., remarkable for the long point which terminates its leaves, generally deeply indented at the stop. Scutellaria parvula, Mich. which presents itself in Japan in forms which it is difficult to consider otherwise than as distinct species. Satureia Japonica, Fr. and Sav., received from Mr. Tanaka, under the name of Arita Soo.
In the Niko hills I have also had the satisfaction of gathering the beautiful Nepeta Macrantha, Fish., known only in Siberia. I have also received from Yedo a small species of Salvia, the exact source of which it would be interesting to ascertain. It is perfectly delineated in the Soo Mokou, Vol. 1., p. 30. We have called it the Salvia Yedoensis, Fr. and Sav.
Polygoneæ. Polygonum propinquum, Led., P. Maakianum, Regel, from Niko; this is the species named later by Meisner, P. hastato-trilobum. P. humile, Meisn., common in the Hakone chain.
Aristolochieæ. I can mention the existence, in the neighbourhood of Yokoska, of the Asarum Albivenium, Regel, the native place of which was unknown to M. Maximowicz.
Euphorbiaceæ. Euphorbia Onæi, Fr. and Sav., which is allied to the E. Pekinensis, and the E. Rochebruni, Fr. and Sav., recalling sufficiently the E. Jolkini.
Urticeæ. I have received several interesting species belonging to this family from Mr. Tanaka, not yet made known in Japan. Memorialis hirta, Wedd.; Pilea strangulata, F. and Sav., curious from its articulated stalk; it is well delineated in the Soo Mokou, vol. 20, fol. 15. I gathered at Yokohama the Pellionia densiflora, Fr. and Sav., and, in the Hakone hills, another species also be-
