The var. (3. 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 2è or 34 broad, spotted like those of the plant from the
United States. The flowers are from 24 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 distinguished
from J . castaneus by the broad sepals of», 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.
