The var. £. only is in Mr Douglas' collection, and what is remarkable, no form of this species appears to 

 have been elsewhere observed on the west side of the Rocky Mountains. The stem is from eight to fifteen 

 inches high, the leaves three or four inches long, and 2 J or Si broad, spotted like those of the plant from the 

 United States. The flowers are from 2| to 3 inches long, and purple, as figured in the Botanical Magazine.

We have only the second variety from California. In the Flor. Bor. Am. this was principally distinguish- 

 ed from J. castaneus by the broad sepals of a, and the capsule as long as the perianth. In J. castaneus, 

 however, the sepals are only about half the length of the capsule, and are entirely brown, membranous and 

 3-nerved.
