I noticed in a recent number of the Monthly some notes on the number of different species of plants that were found in going a mile in New York in comparison with California, and being curious to see how New Jersey compared with them I counted them on several occasions. The greatest number found was from the little village of Green Bank in Burlington county, one mile along a road across the Mullica river into Atlantic county, where I found two hundred and twenty-seven. On another occasion, in a place with less variety of soil, I found one hundred and ninety-eight. I did not count some plants that had escaped, and I counted ferns and lycopods of which there were six. Hammonton, N. J., Oct. 7th, 1885.
