44 IMPATIENS FULVA.—SPOTTED TOUCH-ME-NOT, OR SNAP-WEED, 
1877 of the same serial Mr. W. W. Bailey, of Providence, R. I, 
remarks on a friénd of his finding “the sacs all perforated by 
bumble-bees,” and adds: “You may remember that Dr. Gray 
says this is only likely to happen in a profusely flowering species.” 
Another writer somewhere, but the exact reference not at hand, 
remarks that it has been reported that the leaves hang down at 
nightfall, and become horizontal soon after daylight—a statement 
the writer of this has confirmed by actual observation. Many 
of these behaviors are by no means confined to the /izpatiens 
fulva, but they all afford interesting observations to the curious 
student. 
Besides its value in connection with its scientific lessons, it has 
a directly practical use to man, for Mr. Nuttall, on the authority 
of Dr. Barton, says it is sometimes used for dyeing salmon color; 
and it is said by others to be useful when applied to portions of 
the skin poisoned by the common poison vine, Rhus loxtcoden- 
adroi. 
In its geographical range it is confined on the Atlantic slope 
of our country to that portion east of the Mississippi and Mis- 
souri, except to a small tract within Arkansas, growing chiefly in 
low or damp places. According to Torrey and Gray it is also 
found on the north-western portion of the Pacific slope. 
Dr. Darlington gives as the prevailing common names 
“Tawny Impatiens” and “Spotted Snap-weed;” the last being 
more easily understood by people who are not botanists, we have 
proposed for adoption.
