. - ?is (Mustard). 



1. 8. arverui* (Wild Mustard, Cherlock). Pod* with 

 many angles, rugged, longer than the awl-shaped beak ; 

 leaves toothed, rough. A common weed in corn-fields, 

 and sometimes springing up profiisely from ground 

 which has recently been disturbed, though unknown 

 there before, FL all the summer. Annual. 



2. & alba (White Mustard). Pod* bristly, rugged, 

 spreading, shorter than the flat two-edged beak ; leaves 

 pinnatifid. Waste ground ; flower* large, yellow. The 

 young leaves of this species are used as salad. FL June. 



3. S. nigra (Common Mustard). Pod* quadrangular, 

 smooth, slightly beaked, dose pressed to the stalk; 

 lower leaves lyrate ; upper linear, pointed, entire, 

 smooth. Taller than either of the preceding, bat bear- 

 ing smaller flowers. The seeds yield the mustard of our 

 tables. FL June, July. Annual. 



The Mustard-tree of Scripture is supposed, by some 

 authors, to be a species of Sindpis closely resembling 

 the British plants of the same genus. But inasmuch as 

 this plant, though more luxuriant than any with which 

 we are acquainted, never attains the dimensions of a 

 tree, it has with some probability been conjectured that 

 the plant in question is the khardal of the Arabs, a tree 

 abounding near the aea of Galilee, which bears numerous 

 blanches, and small seeds, having the flavour and pro- 

 perties of Mostazd.
