Observations.— Jn wetting the plant for examination, the leaves 

 nearly all fall off, far more so than in FruUania fragilifolia. The 

 plant has a reddish color, the lobule very large and underleaves small. 

 I found iiuincrous involucres but no perianths. Gemmae are very 

 abundant on the margin of the leaves.
