enough to admit of a distribution. These Salvinias Were col-
lected early in October, but were overlooked in the first exami-
nation of material. Not until they had separated from the mass
of Lemnas, Myriophyllums and Potamogetons with which they
were gathered were they noted. Six good-sized plants <$re at

Salvinia natans (L.) All., in Minnesota.
This very interesting heterosporous pteridophyte is apparently
rare in North America. It is reported in the fifth edition of Gray’s
Manual, as probably not occurring in North America,, although
Pùrsh is supposed to have found it in Western New York. . In
the sixth edition this uncertainty is somewhat dispelled by a re-
port of the plant from Missouri, but no authority is given for the
station.. It is, therefore, an important discovery which this note,
chronicles, viz., that Sctlvinia natans (L.) All., grows in Swee-
ney’s Twin Lake, four miles west of the city of Minneapolis.
Only a few plants have been found and these have been trans-
