cylindrical, tapering at base into a sharp hair-like termination, 
separating upwardly from the axis, and hanging suspended from 
its apex; central axis 3-winged. Seeds loose in the кәкре 
straight, the raphe marked by a purple line. 
This species is readily recognized by its very slender, erect 
scapes, and its racemes of slender, erect, club-shaped and long cap- 
illary pedicels. 
It grows in boggy places or sometimes in slightly wet grounds, 
or in moist sands by brooksides and brackish pools and ponds. 
I found it quite abundant near the Niagara Falls on the Canada side. 
It also occurs at various localities in Western New York, and thence 
westward to Montana (Belt River Canyon, Williams) and north- 
ward through Canada from New Brunswick to Alaska (Macoun). 
Common in the British Islands and throughout Europe and 
Northern Asia. (Plate XX, with a ripe fruit magnified.) 
2. TRIGLOCHIN STRIATA, R. and P. Fl. Peruv. iii. 72 (1802). 
T. triandra, Mx. Fl. 1. 208 (1803). 
Small perennials from upright or oblique, stoloniferous root- 
stocks. Scapes 1 or 2 from the same rhizome, more or less angu- 
lar, usually not over 10 inches high, but sometimes reaching an al- 
titude of 14 inches. Leaves slender, slightly fleshy, nearly or 
quite as long as the scapes and 1-і line in width. Flowers very 
small, light yellow or greenish, in spikes or racemes, with pedicels 
only 12-34 line long, not increasing in fruit, the spikes 1-5 inches 
in length. Perianth segments 3; stamens 3, oval, large. Ovaries 
3, united, crowned with long plumose stigmas. Fruit globose, 
34-1 line in diameter, appearing 3-winged when dry by the con- 
traction of the carpels. Carpels 3, coriaceous, rounded and 3- 
ribbed on the back. Central column broadly 3-winged, the 
wings composed of a thin membrane with a strong rib-like border. 
Seeds loose, slightly curved, the raphe inconspicuous. 
Our species belong to the form called robustior by Micheli. 
Two other smaller and more slender forms are described, named 
Jfilifolia and humilis, the former from the Pacific islands and the 
latter from Chile. 
7. striata seems to take the place of our other species in the 
Southern States, occurring along the seaboard from Maryland to
