'I'm- iare and interesting plant was long ago proposed as a 

 distinct genus by the late Mr. Rafinesque. It is allied both to 

 Fritillaria and to Lilium, It differs from both in the want of 

 nectaries. Unfortunately the fruit is not known, so that it can- 

 not be compared with those genera in an important character. 

 Our specimens are all two-flowered. The root is flat, orbicular, 

 and toothed round the border, with a cluster of little tubers on the 

 upper side at the base of the stem. The leaves are linear, and 

 from two to four inches long. The flowers are yellow, nodding, 

 about an inch in length, somewhat obconical, or funnel-form, and 

 entirely destitute of a nectariferous groove. The stigma is simple 

 and undivided. 



According to Mr. Nuttall, Fritillaria iulipoefolia of Caucasus is 

 another species of this genus. I have also specimens of what may 

 prove to be a third species, collected by Colonel Fremont on the 

 Feather River, California; for the style, though thickened at the 

 summit, is undivided, and the nectary is wanting: but there are 

 several flowers in a loose racemose panicle.
