Sisymbrium Thaliana March 17, 1878<br />
Besides Druba verna, a January species, and Anemone Hepatica, a Februaiy one, the<br />
only herbaceous flower found was Sanguinaria Canadensis. On April 10 High Island<br />
was visited, but only 8 species could be added to the above 7, and several of these, as<br />
Jeffcrsorria diphylla, Dicentra. Cucullaria, Saxifraga Virginicnsis, Eri/fhronium Americannm,<br />
and Stellaria puhcra, were very sparingly out. Cold weather continued to the end of<br />
the third week in April, and on April 24, when High Island was again visited and a<br />
thorough canvass made, only 2'2 additional ])lauts could be found there, and the whole<br />
number seeu to that date was 4(5. The conclusion was that up to that time the season<br />
was about three weeks later than that of 1880.<br />
