This we had taken for the Vilfa algida, {Phippsia, Br.) but it is larger, and certainly the V. monandra 

 of Trinius, who observes that it is the var. of P. algida, mentioned by Mr. Brown, as found by Mr. Nelson, 

 at Tschutski. Chamisso also discovered it in the Bay of St. Lawrence.

There are two states of this plant, as it appears to us, in the Collection ; a purple-flowered one, with 

 usually a single flower only in each calyx, and a yellow-flowered var., with two flowers in each calyx, 

 one upon a rather long stalk. In other respects, the characters are the same. The lower branches of the 

 panicle are often horizontally patent, sometimes completely deflexed.
