Hab, Banks of the Columbia. Scouler. Douglas. — Somewhat allied, especially in habit, to C. macropkylla, 

 ( Gmel. Sib. v. 3. t. 62,) which diiFers in having smaller leaflets, from 5-7 on each leaf, and which are dis- 

 tinctly, and with considerable regularity, serrated; whereas, In our C, anyulata, there are few and distant 

 angular teeth and segments. I have seen it only in Mr, Douglas and Dr, Scouler's collections, who observe 

 that it is not uncommon about Fort Vancouver, on the Columbia.

Hab. From Canada to the Rocky Mountains, and to the shores of the Arctic Sea. Drummond. Dr, 

 mdiardson. Unalaschba. Chamisso. Columbia. Scouler, — Those who have been'in the habit of observing 

 C, hirsutOi as it grows with us, in different soils and situations, and at different seasons of the year, are well 

 aware how liable it is to vary in size and ramification, in the direction of its stems, in the breadth and 

 length and toothing of the leaflets, and somewhat too in the size of its flower. Even the style is more or 

 less distinct, sometimes quite obsolete. The same states occur in North America, whence have arisen the C 

 virginica and C. pennsylvanica ; this latter being eaten in Charleston, South Carolina, Mr. Elliott tells ui, 

 like the garden Cress, as is our C. hirsuta. My specimens of them quite correspond with our European 

 states of the plant. I have placed a mark of doubt against the C. parviflora of Linn., because Sir James E. 

 Smith says it is clearly a distinct species; yet he refers to Gmelin's Fl Sibirica, v. 3. t. 64-, which perfectly 

 accords with many of my American and English specimens, such as are but varieties of C. hirsuta. The 

 species is probably very extensively distributed over the g-Iobe. I have it from Nepal and from Chile. * It 

 exists, too, in Persia.
