FUMARIACE^. 



Dicentratmiftora, Kelloggined., (by Professor Thomas 0. Porter.) Dwarf, 

 3-5'; scape 1-flowerecl, furnished with one or two linear bracts ; flowers 

 6-7" long, apparently purple; sepals oblong, obtuse, 3-4" long, deep 

 purple; outer petals contracted in the middle, the lower half with short 

 rounded spurs, the upper hooded part oblong and, widely recurved, 

 spreading ; inner i)etals abruptly expanded above the claw into sharp 

 triangular wings, not crested. Summit of a mountain near Ogden, 

 Utah Territory, and in the Teton Range at 10,000 feet altitude. Mr. 

 Coulter says, " It grows on the mountain tops where the snow 

 has just melted, or even rarely in the snow itself. No leaves or any 

 trace of them were found, although the plant was collected both in June 

 and August. I had described this plant as a new species, and named 

 it D. nivalis, when I learned from Dr. Gray that it had been discovered 

 in the Sierra iTevada, as early as 1870, by Mr. Kellogg, who was about 

 publishing it as D. uni flora.
