Brown Co., Wisconsin, 750 miles (as far as from New York to Milwaukee 
or Savannah or from Chicago to Bridgeport, Conn., Wilmington, N. C., 
or Winnipeg) to Fort George. 
Crane Lake, Assiniboia, 175 miles (as far as from New York to Boston or 
from Chicago to Indianapolis) to St. Mary’s River. 
Table-topped Mt., Quebec, 20 miles and a descent of 3000-4000 feet to 
the gravel deposits of the lower River Ste. Anne des Monts. 
Mt. Albert, Quebec, 20 miles and a descent of nearly 4000 feet to the 
gravel deposits of the lower River Ste. Anne des Monts. 
Turin, Marquette Co., Michigan, 625 miles (as far as from New York 
to Grand Rapids or Columbia, S. C., or from Chicago to Ottawa or 
Baltimore) to Fort George. 
Pluma, South Dakota, 150 miles (as far as from New York to Harrisburg 
or from Chicago to Dubuque) to the Rocky Mountains. 
Incidentally, the “hybrid” E. angustifolium of Surrey, England, listed 
by Forsaith, is toward 1000 miles (and half that distance across the 
North Atlantic) from Iceland, the nearest area where E. latifolium 
is indigenous; likewise the production of the “hybrid” E. angusti- 
folium from Sapporo, Japan, must have proved a difficult problem 
for the bees, since it is necessary entirely to leave the Japanese Archi- 
pelago in order to find any E. latifolium. 
These data, easily verified in any large herbarium, should be suffi- 
cient to indicate that when Forsaith apologized for the West Virginian 
specimens with imperfect pollen by saying that these “ without doubt, 
have resulted from physiological conditions” (p. 474), he should have 
extended a similar explanation for much of the other material with 
imperfect pollen. 
Forsaith states that the hybrid nature of these plants “is strikingly 
evident from the morphological standpoint”; yet nowhere in his 
discussion does he make a comparison of the obvious morphological 
differences of the stems, leaves, styles, stigmas, and seeds, nor suggest 
that in these most patent characters do the “hybrids” show the slight- 
est degree of blending or of inconstancy. Haussknecht, who freely 
recognized hybrids in Epilobium, and the many other taxonomists 
who are equally ready to recognize them between some species of the 
genus, have seen no reason even to surmise that hybridization occurs 
between E. angustifolium and E. latifolium; and if Forsaith has made 
the real discovery that such hybrids exist it is a pity that he did not 
point out in which of the many strongly divergent characters his 
hybrids show recombinations. That the two species are highly vari-
