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 friend 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 Impaticns 

 fuha, but they all afford interesting observations to the curious 

 student. 



Besides its value in connection with its scientific lessons, it has 

 a direcdy 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 toxicoden- 

 dron. 



In its geographical range it Is confined on the Adantic slope 

 of our country to that pordon 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 pordon 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.
