in their upper epidermis but not unfrequently I could not detect any trace 

 of them. The length of the style and of the pedicel varies to a certain de- 

 gree, and the shape of the gland is not always alike. These variations need 

 further study. As to the Yukon plant at Dawson Miss Eastwood in afield 

 note makes the following statement: '* In habit it is variable but is generally 

 tall and erect with dark red glossy stems. Some bushes have pendent 

 branches, and some have almost fastigiate branches. It often becomes 10- 



feet hitrh, and forms a creat deal of the W
