 Alpine  and Arctic Europe, Asia  and North-America.  Deserves  to  
 be  transferred  to  other  higher  mountains  as  a  nutritious  perennial  
 pasture-grass.  P.  Sndetica  (Haeiike)  and P.  hybrlda  (Gandin)  are  
 mentioned  also  as  excellent  alpine  grasses. 
 P o a   a q u a tic a ,  Linné.  {Olyceria aquatica.  Smith.) 
 Europe, Northern  and  Middle  Asia, North-America.  This  conspicuous  
 water-grass  attains  a  height  of about  6  feet.  I t  is perennial,  
 and deserves  naturalisation  in  onr  swamps.  I t   produces a  large  bulk  
 of  foliage,  and  may  be  disseminated  for  fodder-purposes.  On  the  
 testimony  of  Dr.  Cnrl,  this  is  one  of the  best  feeding  grasses  in New  
 Zealand. 
 P o a   a r a c h n ife ra ,  Torrey.* 
 The  Blue  Grass  of  Texas.  Prairies  of  Louisiana  and  Texas  
 Perennial,  with  creeping roots.  I t   spreads  rapidly,  surpasses  iu  sizè  
 the  Kentucky  Blue  Grass  (Poa  pratensis),  and  is  known  to  have  
 grown  10  inches  in ten  days.  Stock  of  all  kinds  have  a  predilection  
 for  it.  The winters  of  Texas  do  not even  nip  it,  but  it  dies  down  
 during  summer  ;  it  is  never  quite  tramped  out  [G.  Hogan],  I t  bears  
 heavy  pasturing,  and  can  also  be  utilised  for  lawns  and  as  a  forest-  
 grass  [S.  Ta lly ].  For  permanent  pasture,  this  promises  to  be  one  of  
 the  very  best grasses  yet  brought  to  the  attention  of  the  Southern  
 States  (Dr. Vasey]. 
 P o a   Bergii,  Hieronymus. 
 La  Plata-States.  Supplies  excellent  fodder  there,  with  some  
 species  of the  section Eragrostis. 
 P o a   BiUardieri,  Steudel. 
 Extra-tropioal Australia.  A  perennial  rigid  grass,  of  some  value  
 for  saline meadows. 
 P o a   b u lb o s a ,  Linné. 
 Europe,  North-Africa,  extra-tropic  Asia.  A  perennial  species.  
 Dr  J . Aitchison  singles  it  out  for  laudation  as  a  profuse  pastiire-  
 and  hay-grass  in Afghanistan.  Closely  allied  to  it  is P .  alpina, L. 
 P o a   cæ sp ito s a ,  G.  Forster. 
 Extra-tropical  Australia  and  New  Zealand,  ascending  alpine  
 rievations.  A  tufty  extremely variable  grass,  available  tliroughont  
 the  year  for  pasture-feed, when  young  or when  offering  flowering  or  
 seeding-stalks,  or  when  presenting  tender  varieties  ;  the  rougher 
 varieties  utilised  by  the  aborigines  for  nets  and  cordage.  Resisting  
 drought.  Well  worthy  of  being  naturalised  in  other  parts  of  the  
 globe.  Refer for  further  information  on  this  and  other N.Z.  grasses  
 to  J .  Buchanan’s  special  work,  in which  P.  anceps  (Forster)  is  also  
 mentioned  as  important.

 P o a   C h in en sis,  Koenig.  (Leptochloa Chinensis,  Nees.) 
 Southern  and  Eastern  Asia,  East-Australia.  Recommended  by  
 Mr.  F. M.  Bailey  as  a  valuable  pasture-grass,  perhaps  on  account  of  
 its  tender panicles. 
 P o a   Colensoi,  J . Hooker. 
 New  Zealand,  up  to  5,000  feet.  This  tufty  grass  is  greedily  
 devoured  by  sheep, which  thrive well  on it.  Holds  its  ground well,  
 being  of  great vitality  [D.  Petrie]. 
 P o a   c om p re s s a ,  Linné. 
 Europe,  North-  and  West-Asia.  A  perennial  grass,  valuable  for  
 pastures.  Will  grow  in  pure  sand.  Has withstood  prolonged  and  
 severe  drought  [Edw.  Quin].  Also  a very  eligible  lawn-grass. 
 P o a   d ig ita ta ,  B.  Brown. 
 South-Eastern  and  Central  Australia.  Valuable  for  fixing  wet  
 river-banks  and  slopes.  I t   forms  large  stools.  Cattle  and  horses  
 relish  the young shoots. 
 P o a   d is ta n s ,  Linné. 
 Europe, North-Africa, Middle  and Northern Asia, North-America.  
 Perennial.  I t   is  one  of  the  limited  number  of  tender  grasses  
 suited  for  moist  saline  soil,  and  thus  affords  pasturage  on  coast-  
 marshes. 
 P o a   flu ita n s ,  Soopoli.  (Festucafluitans.  Linné;  Glyceriafluitans,  R.  Brown.) 
 The Manna-grass.  Europe,  North-Africa,  Middle  and  Northern  
 Asia,  North-America,  East-Australia,  New  Zealand.  Perennial.  
 Excellent  for  stagnant water  and  slow-flowing  streams.  Waterfowl  
 are  very fond  of  it.  The  foliage  is  tender.  The  seeds  are  sweet  
 and  palatable,  and  in  many  countries  are  used for porridge.  This  
 grass  is  indigenous  in Norway northward  to  lat. 69° 9'  [Schuebeler].
