known. Leersia oryzoides, L.; Phleum asperum, var. annuum. C. Koch. a species only known in the Caucasus; Calamagrostis epigeios, L.; C. Nipponica, sp. nov. C. Hakonensis sp. nov.; Dactylis glomerata L.; Setaria viridis L.; Setaria pachystachys sp. nov.; two new Andropogon, not yet named.
Lycopodiaceæ. Lycopodium Complanatum, var. Chamæcyparissus, Al. Br. from the Niko hills: Salaginella Kraussiana. Kunz. of which the S. Nipponica Miq., is probably a synonym. The Japanese specimens are exactly like those which I have gathered at Madeira and at the Cape of Good Hope.
Filices. I have gathered a certain number of species new for Japan, but the analysis of them is not yet completely finished. I will only mention a Craspedaria, the Cænopteris odontites; the Woodsia Mandshuriensis, and an Ophioglossum closely allied to the O. ovatum, Bory., if not identical with it.
This long enumeration will give an idea of the number of new plants, interesting to geographical botany in general, and to that of Japan in particular, which might be collected in the course of more sustained and profound researches than it has been possible for me to make.
The relations existing between the flora of Japan and that of Eastern Asia on the one side, and that of the eastern region of North America on the other side, have already been observed. The known species which I have enumerated confirm the conclusions drawn from previous observations, and if Siberia can claim as indigenous the Atragene macrosepala, Clematis fusca, Corydalis Raddeana, Viola variegata, Geranium pseudo-sibiricum, G. Wlassowianum, G. dahuricum, Senecio davuricus, Saussurea Ussuriensis, Nepeta Macrantha, Perularia fuscescens, Cyperus truncatus, Woodsia Mandshuriensis. Northern America has hitherto enjoyed exclusive possession of the Polygonatum pubescens, Carex lupulina, Carex crinita, C. lagopodioides, Hamamelis virginica, Stenactis ambigua.
Europe also brings its modest contingent with the Cy-
