or all indented. Pouches roundish, fleshy, much larger than those of 
C. officinalis, and terminated by a longer style about two-thirds of a line 
in length. Woodw. (This species likewise varies in the size and shape 
of its parts, but is always smooth and rather fleshy, scarcely half the size 
of C. officinalis. Pouches all over strongly marked with a net work of 
prominent veins, scarcely at all to be perceived in those of the more 
common kind. E. Bot. E.)

* (This species is supposed to possess, though perhaps in an inferior degree, the same 
medicinal virtues as C. officinalis. They are considered to promote the fluid secretions ; 
and to open glandular obstructions. They are much employed in the scorbutic dis¬ 
orders prevalent in northern countries. Some authors have conjectured this, (or our other 
officinal species), to be the real Herba Britannica of Pliny, from the use of which the army 
of Caesar derived great benefit in their sufferings from seurvy whilst in Germany. Olaus 
Magnus also 0011(111118 its efficacy. E.)
