4lf TRIANDRIA. 



ment. ^lagnificent and valuable works 

 on this family have been published in Ger- 

 many by the celebrated Schreber and by 

 Dr. Host. The 17. Grceca also is rich in 

 this department, to which the late Dr. Sib- 

 thorp paid great attention. Much is to be 

 expected from scientific agriculturists ; but 

 Nature so absolutely, in general, accom- 

 modates each grass to its own soil and sta- 

 tion, that nothing is more diflicult than to 

 overcome their habits, insomuch that few 

 grasses can be generally cultivated at plea- 

 sure. 



3. Trigipua is chiefly composed of little 

 pink-like plants, or Cari/ophijllcce, as Ho- 

 losteum^ Engl. Bot, t. 27- 



Tilhea muscosa, t. Il6, has the number 

 proper to this order, but the rest of the 

 genus bears every part of the fructification 

 in fours. This in Linna^an lansfuafre is ex- 

 pressed by saying the flower of Tillcca is 

 qnadrijidia^'% four-cleft, and T, muscosa 

 excludes, or lays aside, one fourth of the 

 fructification.
