74 IIORTUS GRAMINEUS WOBIJ UN E N S IS. 



This Cataloiiuc contains about one thousand five hundred 

 distinct species and varieties of the proper grasses, of which, 

 upwards of one hundred and fifty are indigenous to Great 

 Britain ; but, as the discoveries of botanists still continue 

 to add to the number of new species and varieties, the term 

 complete cannot be applied to this enumeration. The highly 

 valuable and important works of Sir James Edward Smith, 

 of Brown, Humboldt and Bonpland, Decandolle, Poiret, 

 La Gasca, and other eminent botanists, have of late pre- 

 sented to the attention of the agriculturist many new species 

 of grasses.
