 curious species, resembling a reduced Platycodon Grandiflorum.

Ericaceæ. Monotropa Japonica, Fr. and Sav., a poor species with velvety bell-shaped flowers, and with long pedicules: can this be the M. hypopithys, variety hirsuta, cited by M. Maximowicz as from the Niko hills?

Primulaceæ. The Lysimachia vulgaris, L. forma typica, grows in the environs of Hakodate. The Lysimachia Davurica, sufficiently common in the north of Japan, is probably a simple variety of this plant.

Oleaceæ. Linociera Japonica, Fr. and Sav., which seems sufficiently distinct from the American varieties.

Gentianeæ. Gentiana brevidens, Fr. and Sav. from Niko. G. Nikoensis, Fr. and Sav., also from the Niko hills, where it grows at a great altitude. It is a charming species with greenish leaves, found by Mr. Kramer, and might easily be mistaken for the G. decumbens, if the lower part of the stern were not completely bare of root fibres. It must be placed by the side of the G. Pneumonantha, and G. triflora.

Asclepiadeæ. The genus Vincetoxicum already represented by six species, according to Miquel, must be increased by two new ones. V. Brandtii and V. Vernyi, Fr. and Sav., both received from Mr. Tanaka.

Convolvulaceæ. Cuscuta Vernyi, Fr. and Sav. a species with large flowers, a parasite of the vitex unifoliata, in the sand of Kamakoura,—cuscuta minor, L.

Borragineæ. In his eleventh chapter. M. Maximowicz expresses his surprise that neither in Japan, nor in the neighbouring countries, the Echinospermum lappula, L. has been found. This gap is now filled, as I have received the plant from Hakodate. The Cynoglossum micranthun, the existence of which in Japan, although mentioned by Miquel, has seemed doubtful to M. Maximowicz, certainly grows in the province of Koshiu, where it was found by Mr. Kramer, and in the Niko hills, where I also found some specimens of it.

Scrophularineæ. I may cite as belonging to Japan, in this family, a Dopatrium, closely connected with the
