This is a very common plant in Europe, from whence it has 

 migrated to this, as well as to almost every other region of the 

 globe. Thus, it has been found in India and the Mauritius, 

 and at Magellan's straits and the Cape of Good Hope. In 

 the specimens met with in this Island, the leaves towards the 

 bottom of the stem are petiolated, obovato-oblong, attenuated 

 at the base ; those of the stem, lanceolate-sagittate ; all of them 

 acute, toothed, hispid with stellated hairs. Seeds 10 in each 

 cell ; under the glass minutely punctulated. 



V. SISYMBRIUM. Hedge-mustard. 



Pod rounded or angular. Cotyledons incumbent, 

 (Oil) sometimes oblique, plane. Calyx patent, some- 

 times erect. Brown. 



Name, from ciauppgiov, the designation of some plant probably 

 allied to this genus. 



1 . Sisymbrium officinale. Common Hedge-mustard. 



Pods subulate pubescent closely pressed to the 

 main-stalk, leaves muricated hairy, stem hispid. 

 Brown.

FL. Throughout the year. 



There cannot be a doubt but that this is identical with the 

 species which bears the above designation, and which is com- 

 mon in every part of Europe. The only point of difference is, 

 that the pods, in our Jamaica specimens, are, when young, under 

 the glass sparingly puberulous, but afterwards glabrous. This 

 is the case, according to Pursh, in the specimens collected by 

 him in South Carolina.
