The branching, straggling, common mustard, with bright 
yellow flowers (one-third inch broad) in raceme, replaced by 
upright, three-quarter inch pods. The lower leaves have large

Summer. 
An annual, or biennial, rarely over two and one-half feet 
high, stem stiffly hairy below, flowers Jew, pale and large (some- 
times three-fourths inch across); its pods are sometimes two 
inches long and suggest pea-pods, on account of constrictions 
between the seeds. The leaves are coarse and rough, the lower 
with a large terminal lobe and small lobes below. Fields and 
yards. The Latin raphanus means radish. , 
Wild Mustard. Charlock (Brassica arvensis). Mustard

A small-flowered (one-half to two-thirds inch), sparingly

the lower with short, flat stalks, the upper practically without 
stalks. Common in open places. 
Hedge Mustard {Sisymbrium officinale). Mustard family. 
May to September. 
An upright, stiffly branching mustard from one to three feet 
tall. The flowers are very small, less than one-sixth inch broad; 
few are in blossom at once. The flowers are replaced by small 
linear pods, pressed close to the stem. Leaves long and pointed, 
pinnately cut with lobes turned backward, lower leaves with 
stalks. Waste ground.
