44 WEEDS AND USEFUL PLANTS. 



Obs. This plant, a native of Canada, and the country further north, 

 is cultivated in the gardens, near Philadelphia, under the name of 

 " Scurvy-Grass," and is becoming spontaneous farther south. The 

 leaves afford a tolerable salad, but not equal to the common cress (Lepi- 

 dium sativum, L.,) nor to the Water-cress (Nasturtium officinale, R. Br.) 

 There is another and stouter species (B. vulgar is, R. Br., probably 

 naturalized), growing along our streams, which is sometimes used as a 

 salad, but it is bitterish and inferior in quality to this.

[An ancient Greek name, applied to this genus.] 



Silique somewhat terete ; 4-6 sided ; valves 1 - 3-nerved. Seeds 

 oblong, marginless. Annual or perennial herbs. Leaves various. 



L S. officina'le, Scop. Lower leaves runcinate, upper ones some- 

 what hastate ; racemes slender and virgate ; siliques erect, awl-shaped,

 Aug. Fr. Aug. - Oct. 



Obs. This foreigner is completely naturalized, and somewhat trouble- 

 some as a weed. It was formerly held in some repute, in Europe, as a 

 remedy for coughs, the hoarseness of singers, &c. (whence its French 

 name) ; but its virtues were doubtless overrated, and it is now regarded 

 by tidy farmers in this country merely as a plant to be expelled from 

 their premises. 



4. BRAS 'SIC A, L. CABBAGE. TURNIP. 



[Supposed to be from Bresic, the Celtic name for the Cabbage.]

 a central nerve. Seeds in a single series, globose. Foreign plants : 

 mostly biennial herbs, with a short stem and long flowering branches.
