been set down, one may be puzzled to decide whether the re- 

 maining forms are true denizens of the region or not, but a 

 little investigation will usually show that one locality has more 

 claim tO' a given species than any other. Just because a few 

 cat-tails are found in ;a bog is no sign that they are naturally 

 bog plants. They are really marsh plants though a few may 

 linger in a bog for some time. To discover the interest there is 

 in arranging plants according to habitat, set down a list of the 

 bog plants of your region, taking care that no plant except 

 those that naturally grow in cranberry or sphagnum bogs is 

 admitted to the list. 



Color Forms of Lilium Canadense. — There are no red 

 specimens of Lilium Canadense — if you leave it to the books. 

 Harper's ''Guide to the Wild Flowers" calls them golden yel- 

 low, Mathews ''Field-book of American Wildflowers" names 

 them buff-yellow. Gray and Wood both call the flowers yellow 

 or orange, while Britton alone hints that they may be red. 

 Most of the botanical books are made in the East where this 

 lily is nearly always yellow, which may account for the color 

 attributed to it, but notwithstanding this, the flowers are prac- 

 tically always red in northeastern Illinois and in southern 

 New York. Possibly the difference in color is after all a north- 

 and-south difference, the flowers being yellow in the southern 

 part of the plant's range and red further north. The flora of 

 eastern New England has many elements of more southern 

 regions in it and its lilies should naturally be yellow. Further 

 notes on the distribution of the color forms of this species are 

 needed. Meanwhile we have twoi additional notes on the sub^ 

 ject. Mr. Leston A. Wheeler, Townshend, Vermont, writes 

 "As regards the color forms of the meadow lily mentioned in 

 the February number of the American Botanist, it may be oi 

 interest tO' note that in West River valley both the red and the 

 yellow flowered forms occur. On July 10th of the present 

 year, in company with a friend, I found both forms and noted
