Latifolii 



Herbaceous perennials frequenting woodlands and borders 

 of thickets. Steins rather tall, up to about 10 dm., more or less 

 branched, not succulent, sparingly pubescent with short ap- 

 pressed hairs. Basal leaves smaller than those of the middle 

 part of the stem, the petioles not elongated. Flowers violet, sub- 

 symmetrical at base. Plants of the Pacific slope. 



This is part of the section Rivnlares of Piper's Flora of 

 Washington, also made to include the Polyphylli. But the 

 name Rivnlares can not stand, for none of the plants mentioned 

 there are related to L. rivularis.
