1. Oxalis Oregana, Nutt. in Torr. & Oray. 



Hab. Puget Sound. — There is but a solitary specimen of this plant 

 in the collection, and the flower is un expanded. It is certainly very 

 like 0. acetosella, but seems pretty constantly to differ in the charac- 

 ters assigned to it by Mr. Nuttall. The flowers are bright rose-color 

 externally, and paler inside. Bracteoles of the peduncles connate at 

 the base. 



2. Oxalis strict a, Linn. 



Hab. Bay of San Francisco and other parts of California. — Diffused 

 under many forms and names over a large part of the world.
