 and  not  scorched  even  by  sirocco-like  blasts.  Its   vast  abundance'  
 over  extensive  salt-bush  plains  of  the Australian  interior,  to  the  exclusion  
 of almost  every other bush  except A. halimoides, indicates the  
 facility with which  this  species  gets  disseminated  of  its  own  accord.  
 Splendid  wool  is  produced  in  regions  where  A.  vesicarium  and A.  
 halimoides  almost  monopolize  the  ground  for  enormous  stretches. 
 ■ With  other woody  species  easily multiplied  from  cuttings  also  ;  but,  
 as  remarked  by Naudin,  producing  thousands  of  fruits  in  less  than  
 three  months  after  sowing,  and,  as  stated  by Millardet, has  become  
 the marvel  of  the Delta  of the Rhone. 
 A tr o p a   B e llad o n n a ,  Linné. 
 The  “ Deadly  Nightshade.”  Southern  and  Middle  Europe  and  
 Western  Asia  ascending  the  Himalayas  to  12,000  feet.  A most  
 important  perennial  medicinal  herb.  The  highly powerful  atropin  
 is  derived  from  it,  besides  another  alkaloid,  the  belladonnin.  The  
 action  of  belladonna  is mydriatic, thus of  great moment  in ophthalmic  
 surgery.  The  eifect  in  other  respects is  very complicated and  heroic.  
 Speaking briefly,  it is  a  narcotic  of  first  rank  ;  amongst  its  uses  are  
 those  against  asthma,  various  spasms,  epilepsy  ;  but  the whole  range  
 of  its  efficacy  cannot be  discussed  in  pages  like  these.  I t   is  an  antidote  
 to  various  vegetable poisons.

 California.  A  shrub,  attaining  a  height  of  10  feet  ;  keeps  the  
 bees  buzzing  with  activity  about  its  flowers  for  honey  during  the  
 whole  spring  [A.  J .   Cook].  The  same  can  be  said  of  A.  Palmeri  
 (Gray)  and  some  other species  of  this  genus. 
 A v e n a   e la tio r,  Linné.  (Arrhenathemm  elatnis,  Beauvois.) 
 The  tall Meadow-Oatgrass.  Europe, Middle Asia,  North-Africa.  
 Indigenous  in  Norway  to  lat.  68°  11'  [Schnebeler],  This  grass  
 should  not be  passed altogether  on  this  occasion, although it becomes  
 easily  irrepressible  on  account  of  its wide-creeping  roots.  I t   should  
 be  chosen  for dry and  barren tracts of country, having proved through  
 its  deeply  penetrating  roots  to  resist  occasional  droughts better than  
 rye-grass.  Hon.  J .  L. Dow  regards  it  as  one  of  the  very  best  of  
 grasses  for  sandy  soil.  Yields  more  green  feed  in  the  Southern  
 States  of  North-America  during  winter  than  most  other  grasses  
 [Loring],  The  hulk  yielded  by  it  is  great  ;  it  submits  well  to  
 -depasturing,  and  gives  two  or  three  crops  of  hay  annually—thus,  a  
 total up  to  80  cwt.  [Steb le r].  I t   is,  however, not  so much  relished  
 bj'  animals  as many other grasses,  and  should never be  sown by itself. 
 A v e n a   f a tu a ,  Linné. 
 Wild. Oats.  Europe, Northern Africa, Northern and Middle Asia,,  
 eastward  as  far  as  Japan.  The  experiments  of  Professors Buckman  
 aud Haussknecht  indicate  th a t  our  ordinary  cultivated  Oat  (Avena 
 sativa L .)  is  descended  from  this  plant..  Cultivated  in  California  for  
 fodder,  as  indeed  it was  in  ancient  times,  but requiring  early cutting,  
 as  it matures  and  sheds  its  seeds  in July.  For  this  reason  it  is  also  
 hard  to  exterminate  it  in  grain-fields,  where  it  sometimes  proves  
 quite  troublesome, unless  by  change  of  crops. 
 A v e n a   fla v e s c e n s ,  Linné,  (ynsciam^oerescens, Beauvois.) 
 Yellowish  Oat-grass.  Europe,  Northern  Africa,  Middle  and  
 Northern  Asia,  eastward  as  far  as  Japan.  One  of  the  best  of  
 perennial meadow-grasses,  living  on  dry  soil  ;  fitted  also  for  alpine  
 regions.  Lawson  observes  th a t  it  yields  a  considerable  bulk  of  fine  
 foliage,  and  th a t  it  is  eagerly  sought  by  sheep,  but  that  it  thrives  
 best  intermixed with  other  grasses.  I t   likes  particularly  limestone  
 soil,  where  it  forms  a  most  valuable  imdergrass,  but  is  not  adapted  
 for  poor  sand,  nor  will  it  stand  well  the  traversing  of  grazing  
 animals  [Langethal].  I t   is  richer  in  potash  than  many  other  
 grasses  [Stebler.] 
 A v e n a   p ra te n s is , Linné. 
 Meadow  Oat-grass.  Europe,  Northern  Asia.  Indigenous  in  
 Norway to  lat.  66°  40'  [Schuebeler],  I t   thrives well  on  dry  clayey  
 soil, is well  adapted  also  for  alpine mountains, where  it would  readily  
 establish  itself,  even  on heathy moors.  I t   produces  a  sweet  fodder,  
 but not  in  so  great  quantity  as  several  other  less  nutritious  grasses.  
 I t   is  perennial,  and  reoommended  by Langethal  for  such  ground  as  
 contains  some  lime,  being  thus  as  valuable  as  Festuca  ovina.  
 Eligible  also for meadows, especially under  a  system  of irrigation. 
 A v e n a   p u b e s c e n s , Linné, 
 Downy Oat-grass.  Europe, Northern, and Middle Asia.  A sweet  
 perennial  grass,  requiring  dry  but  good  soil  containing  lime ;  it  is  
 nutritious  and  prolific,  and  one  of  the  earliest  kinds,  but  not well  
 resisting  traffic.  Several  good  Oat-grasses  are  peculiar  to  North-  
 America  and  other parts  of  the  globe.  The  relative  value  for fodder  
 is  in  many  cases  not  exactly  known,  nor  does  the  limit  assigned  to  
 this  volume  allow  of  their being  enumerated  specially. 
 A v e n a   s a tiv a , Linné.* 
 The  Common  Oats.  In   Middle  Europe  cultivated  before  the  
 Christian  era  and  in  Switzerland  already  at  the  Bronze-age.  A.  
 de  Candolle regards  it  as  probably  indigenous  to Eastern  temperate  
 Europe,  particularly  the Austrian Empire,  thence  perhaps  extending  
 to  Siberia.  Prof.  Haussknecht,  on  linguistic  researches,  favours  the  
 idea,  that  the A.  sativa was  gradually derived from A.  fatua (Linné),  
 the Wild Oats  of Europe  and Northern  Asia;  thus it is  realty also of  
 British  origin.  Annual.  Important  for  fodder,  green or  as  grain—
