In woods, hedges and pastures, frequent. 



Perennial. March, April. 



Root rather woody. Stem none, but the long, trailing, leafy scyons 

 spread very far, throwing out abundance of fibrous radicles. 

 Leaves of a darker green, and more rounded heart-like figure 

 than the preceding, veiny and somewhat wrinkled, but smooth 

 above, though slightly downy underneath. Footstalks nearly 

 smooth. Stipulas lanceolate, with taper-pointed teeth. Flotver- 

 stalks taller than the leaves, with a pair of narrow bracteas above 

 their middle, smooth. Flower drooping, deep purplish blue; 

 pale and streaked in the mouth ; with orange-tipped, uncon- 

 nected anthers ; its scent well known, and universally accepta- 

 ble, though sometimes causing headache. The Jlowers in /3 are 

 white, with a blueish spwr. A double variety, highly fragrant, 

 is cultivated in gardens. 



Mr. Curtis has observed the later flowers, of this and V. hirta, to 

 be often destitute of petals, which is the case with several foreign 

 species. 



3. V. palustris. Marsh Violet.

 branous, nearly entire. Flower-stalks square, with a pair of
