 Floating Poa. 
 Spec. Char.  Panicle  branched;  spikets  long,  and  cylindrical,  containing  many  florets;  
 calyx  smooth. 
 As  an harbinger of better days,  the floating Poa first strikes our attention,  mantling the water with  
 its long  and  handsome foliage,  vegetating amid the chilling airs of our  retiring winters,  and we frequently  
 see the shallow pools  and stagnant waters  margined with  its luxuriant foliage,  when the surrounding  
 fields  are destitute o f food.  "This grass  stands  in the Species Plantarum  as Festuca,  but in  
 the Hortus Cliffordiensis is  associated with Poa.  Haller,  whose thirst for innovation  (or  sometimes  
 perhaps  pointed  deviation  from  his  early friend Linnaeus)  often  induced  him to assign  a  station for  
 plants, which.his better judgment would have known to have been erroneous in another,  has however  
 with propriety ranked this plant with the Poae, the formation of the calyx justifying his arrangement. 
 ■  -This .sweet  and nutritious grass is  a temptation  to the poor hungry beast scarcely  to be resisted,  
 and we  see bullocks,  and  the  field-fed  horse,  wading deep with  much  danger  to  obtain  this  early  
 delicacy:  swine are likewise very fond of  it,  and will gratify their appetites when they are  able.  •  -  
 Perhaps  none  of. our grasses point  out  so  obviously the  advantages  of  irrigation, when practicable,  
 as this plant, the grand  desideratum  being early food:  our springs are frequently late,  f winter lingers  
 in the  lap of May,’ and a black  spring  is mortality;  *  Lolium perenne (grades)  is  looked up to,  and  
 justly,  but  it  comes  not  sufficiently early;  whereas  the  floating Poa,  by  natural  irrigation,  affords  
 much herbage  even in the winter months,  and in  some  places  where  circumstances  have permitted  
 this  grass  and Aira  aquatica  to  increase,  they have been  so abundant,  that  an  idea  has  often  suggested  
 itself that it might have been mown with advantage as soiling,  and conveyed to the firmer grass  
 lands for cattle to eat:  but how far it may be possible to render it subservient to this purpose, practice,  
 combined with judgment, can best determine:  but, at any rate, encouraging the growth o f Poa fluitans  
 in marshy places,  cannot but be attended with advantage,  in enabling waste  and idle land to produce  
 an early and valuable food. 
 The seeds  of this plant  are  made use  of in some places on  the  continent  as  a nutritious addition  
 to soups,  &c.  under the name of Manna seeds.  It has been  a received opinion that the seeds of  Poa  
 fluitans,  although plump and healthy, by some defect or another were not productive o f their species;  
 this  idea  however  is  not justly adopted,  as  the germinating powers  are  equally perfect in them as in  
 any of our grasses,  and, by the earth being kept perfectly moist, they will vegetate and become plants.

 *  We knew  a Norfolk former,  in  the well remembered spring  of  1790  (after  the  severe winter  had exhausted his  
 turnips), who was  necessitated to destroy above 300 lambs,  the  ewes being too weak from want of food to support their  
 young ones.
