Involucrated Oreas. PI. ^ to 1 inch. 



Cult. This plant should be grown in small pots, in a mixture 

 of peat and sand, and treated as other alpine plants ; it can be 

 propagated by dividing the plants at the roots or by seeds. Not 

 worth cultivating except in general collections.

1 C. BU'RSA-PASTO'RIS (Mcench. meth. 271.) O- H. Native

 the rest of the order, and it is rather glutinous to the taste.

Shepherd's-Purse. Fl. March, Nov. Britain. PI. to 1 ft. 



Cult, The Shepherd' s-Purse is well known as a very trouble- 

 some weed in gardens, but it is easily kept under by hoeing the 

 ground in dry hot weather, at or before it comes into flower, 

 but if suffered to seed it will become exceedingly troublesome.

 This plant has got about 20 other synonymous names, but they 

 have now become perfectly obsolete. Sepals roundish, with 

 white membranous margins. Stems spreading, quite flat to the 

 ground. This plant was formerly gathered and used as a salad; 

 but has since been deservedly neglected, the whole herb being 

 nauseously acrid and fetid, and must require much boiling to 

 render it eatable.
