from Antarctic America. The Chilian specimens, which also have 

 very short and densely csespitose stems, are in mature fruit, with the 

 pods dehiscent, and their valves considerably longer than the calyx; 

 they belong therefore to a variety which Dr. Hooker has indicated. 

 None of our plants show any trace of the four bracts on the peduncle, 

 which Kunth's Sagina Quitensis is said to bear.

This species, which is admirably figured and characterized by Dr. 

 Hooker, is more rigid and pungent than any of its congeners.

The essential character of this genus inheres in the petaloid bodies 

 which Chamisso and Schlechtendal took for true petals, and incau- 

 tiously described as alternate with the sepals; whereas they stand
