A BUNCH OF HERBS. 213 



Ground nut (Apios tuberosa}. 

 Adder's-tongue Pogonia (P. ophioglossoides). 

 Horned bladderwort ( Utricularla cornuta). 



The last-named, horned bladderwort, is perhaps 

 the most fragrant flower we have. In a warm, moist 

 atmosphere, its odor is almost too strong. It is a 

 plant with a slender, leafless stalk or scape less than 

 a foot high, with two or more large yellow hood or 

 helmet-shaped flowers. It is not common, and be- 

 longs pretty well north, growing in sandy swamps 

 and along the marshy margins of lakes and ponds. 

 Its perfume is sweet and s^icy in an eminent degree. 

 I have placed in the above list several flowers that 

 are intermittently fragrant, like the hepatica, or liver- 

 leaf. This flower is the earliest, as it is certainly one 

 of the most beautiful, to be found in our woods, and 

 occasionally it is fragrant. Group after group may 

 be inspected, ranging through all shades of purple 

 and blue, with some perfectly white, and no odor be 

 detected, when presently you will happen upon a lit- 

 tle brood of them that have a most delicate and deli-

 oosestrife growing along streams and on other wet 

 places, with tall bushy stalks, dark-green leaves, and 

 pale axillary yellow flowers (probably European). 

 A handful of these flowers will sometimes exhale a 

 sweet fragrance ; at other times, or from another lo- 

 cality, they are scentless. Our evening primrose is 

 thought to be uniformly sweet-scented, but the past 

 season I examined many specimens, and failed to find
