This species, first observed in Scotland, is widely diffused, nor 
does it differ in habit in its various localities,—the typical form, 
as found in maritime sandy shores, and the erect taller form from 
higher altitudes, being observable in all. But in the Rocky 
Mountains, while the habit is typical, the perigynium is not in¬ 
flated, and is regularly nerved. In Europe, Greenland, India, 
and South America, the perigynium is inflated, and in the dried 
state lies loosely in folds over the achenium. The leaves are com¬ 
monly involute, occasionally at base plane, from \ to 1 lin. broad. 
In the ‘ Flora Rossica’ the 0. Curaica of Kunth is referred to it, 
but I have preferred to give a distinct description and figure of 
that plant. I have authentic specimens of both the South Ame¬ 
rican plants, which are undistinguishable from C. incurva.

The only specimen I have seen is in Herb. Hooker. The deli- . 
cate, nerveless, light green perigynium is like that of O. divulsa; 
but the bracts and short stigmata essentially differ from it.

I have only seen one specimen of this plant in Herb. Tucker- 
man, given to him by Schouw, with the name provisionally ap¬ 
plied to it by Hrejer. It is singular that Bertoloni should ally it 
to the Ferruyinem, “ media inter C. tenuem. Host, et C. Scopolii, 
Gaudin,” and yet not refer C. platystachya to the same group, 
as the affinity of the two is so evident.

tis sessilibus erectis atro-purpureis concoloribus, termi¬
