of Brown in Parry's \si Voyage. Mr. Brown describes the 

 scapes as an inch, or an inch and a half high ; here they 

 attain four or five inches. Wahlenberg's figure is rather 

 smaller; but in other respects very characteristic. 



CoCHLEARIA.

 Parry's 2d Voy. App. ined. 



Of a Cochlearia there are two specimens, but having only 

 root-leaves. These however are exactly similar to what I 

 have seen of C. fenesirata ; and as most, if not all, the Cock- 

 learice which I have received from the Arctic regions are 

 referable to that species, so I think it not unlikely that this 

 will have the same character when found in fruit.

This species does not appear to have been found in any 

 of the previous Arctic Voyages of Discovery. I have re- 

 ceived it, however, from Greenland. It is an inhabitant of 

 the northern parts of the continent of North America, in 

 Labrador (Colmaster), Lapland and Greenland. The speci- 

 men in the collection has its upper cauline leaves very broad 

 and coarsel}"- toothed.
