Sisymbrium Thaliana March 17, 1878 



Besides Druba verna, a January species, and Anemone Hepatica, a Februaiy one, the 

 only herbaceous flower found was Sanguinaria Canadensis. On April 10 High Island 

 was visited, but only 8 species could be added to the above 7, and several of these, as 

 Jeffcrsorria diphylla, Dicentra. Cucullaria, Saxifraga Virginicnsis, Eri/fhronium Americannm, 

 and Stellaria puhcra, were very sparingly out. Cold weather continued to the end of 

 the third week in April, and on April 24, when High Island was again visited and a 

 thorough canvass made, only 2'2 additional ])lauts could be found there, and the whole 

 number seeu to that date was 4(5. The conclusion was that up to that time the season 

 was about three weeks later than that of 1880.
