LARGER BUR-MARIGOLD.— In the last edition of the **Manual," Prof. 
Gray ascribes to Bidens chrysanthemoides a maximum height of two and a 
half feet. The writer has recently observed this species growing to the 
prodigious height of from six to eight and two-thirds feet. The locality 
of these large specimens is near a spring in Pratt Co., Illinois. We tried 
the maximum size allowed it by our authors, as in ind do many other 
ul 
ree to five, rather than “two to three," as Professor Gray says. 
But scores of other species might be doni which seem constantly 
to outgrow themselves on our western soils. The flora of the United 
States as it is now known seems remarkable for various forms of the. 
same species; and although future studies will probably identify as dis- 
tinct species many forms now regarded as only varieties, yet remarkable 
differences in the size of the same species in different localities will be a 
more notable feature of our flora when the plants of the east and the 
west, the north and the south, shall have been more thoroughly studied 
and more diligently compared. — EDWARD L. Greene, Decatur, I llinois. 
Tur YELLOW-FLOWERED SARRACENIA PURPUREA. — The remarks of Mr. 
Tracy, on page 327 of the NATURALIST, have somewhat surprised me, as 
the form of Sarracenia purpurea L., there des ee though rather rare, 
has been long and well known. (See Gray’s Manual, ete.) This is, I er 
Eaton, a a. purpurea, var. hete 
rophylla Torr. Under the latter e d in PUA Wc it says it has 
been found at Northampton, Mass. It may be interesting to state in this 
connection, as showing its diti E Pune I collected this form (a 
specimen of which I preserve in my herbarium) more than two o years ago, 
on the south shore of Lake Superior, about thirty miles east of Marquette, 
Michigan. It grew with the common form. In my plant the leaves were 
without purple veins, or had them but very few and pale.
