Pollen granulate with smooth operculum, larger than in N. alba.—Ovary ovate or roundish, usually contracted and destitute of stamen insertions below the stigma.—Carpels 5 to 14; styles linear, flattened, breadth: length = i: to ; apex rounded or somewhat acute. Stigma concave, yellow, red or violet, the rays terminat- ing usually in 3 teeth (a central and two lateral) on the base of each style. Axile pro- cess slender.—Fruit ovoid or spherical; in the former case, narrowed below the stigma, which stands as it were on a short thick column surmounting the berry; greenish or reddish; subtended by the persistent sepals; diameter to cm.—Seed larger than in N. alba, ellipsoid, brownish, cm. long; aril longer than the seed. Leaf cleft at base to the petiole, sub-orbicular to oval, 10 or 12 to 30 cm. long and 25 cm. wide, entire.—Sinus, depth : length of leaf = i: ; lobes nearly equal, inner margins curved, overlapping a little above, and spreading out toward periphery of leaf (or straight, and parallel or touching) ; angles more or less acute. Veins on under sur- face of leaf prominent, the lowest pair (i. e., those running into the lobes) curved, and, if produced, would cross, inclosing an oval area. —Petiole terete, smooth. Rhizome stout, 5 cm. or more in diameter, horizontal, with strong lateral roots, but often without side- branches ; apex surrounded by peti- oles, peduncles and stipules. Phyl- lotaxy about 13 on 34 with very short internodes; the surface of the rhizome may almost be said to con- sist of large leaf-cushions. GEOGRAPHIC DISTRIBUTION.— Northern and arctic Europe and Asia, south to the mountains of Ger- many and the Himalayas. Krumme- See, near Grubno, in West Prus- sia (Caspary 1884). Canton St. Gallen, in Switzerland (Gremli 1882). Lojo in Poland (Lindberg 1881). Herjedalen in Sweden (Behm 1887). Far north in Finland (Saelan
