Douglas.—Three to four feet high, herbaceous. Stem rounded. Flowers large, white, clustered. The leaves
bear a considerable resemblance to those of E. occidental, but the flowers are totally different, larger than
is usual in this Genus, each of many florets, and with the stigmas less exserted than usual. I possess only
a solitary specimen.
