  Oak  \Oak\  ([=o]k),  n.  [OE.  oke,  ok  ak  AS  [=a]c;  akin  to  D. 
  eik,  G.  eiche,  OHG.  eih,  Icel.  eik,  Sw  ek  Dan.  eeg.] 
  1.  (Bot.)  Any  tree  or  shrub  of  the  genus  {Quercus}.  The  oaks 
  have  alternate  leaves,  often  variously  lobed,  and 
  staminate  flowers  in  catkins.  The  fruit  is  a  smooth  nut, 
  called  an  {acorn},  which  is  more  or  less  inclosed  in  a 
  scaly  involucre  called  the  cup  or  cupule.  There  are  now 
  recognized  about  three  hundred  species,  of  which  nearly 
  fifty  occur  in  the  United  States,  the  rest  in  Europe, 
  Asia,  and  the  other  parts  of  North  America,  a  very  few 
  barely  reaching  the  northern  parts  of  South  America  and 
  Africa.  Many  of  the  oaks  form  forest  trees  of  grand 
  proportions  and  live  many  centuries.  The  wood  is  usually 
  hard  and  tough,  and  provided  with  conspicuous  medullary 
  rays,  forming  the  silver  grain.
