From The Free On-line Dictionary of Computing (18 March 2015) :

  tree
  
      A directed acyclic graph; i.e. a graph
     wherein there is only one route between any pair of nodes,
     and there is a notion of "toward top of the tree" (i.e. the
     root node), and its opposite direction, toward the leaves.
     A tree with n nodes has n-1 edges.
  
     Although maybe not part of the widest definition of a tree, a
     common constraint is that no node can have more than one
     parent.  Moreover, for some applications, it is necessary to
     consider a node's daughter nodes to be an ordered list,
     instead of merely a set.
  
     As a data structure in computer programs, trees are used in
     everything from B-trees in databases and file systems, to
     game trees in game theory, to syntax trees in a human or
     computer languages.
  
     (1998-11-12)
  

From Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  TREE. A woody plant, which in respect of thickness and height grows greater 
  than any other plant. 
       2. Trees are part of the real estate while growing, and before they are 
  severed from the freehold; but as soon as they are cut down, they are 
  personal property. 
       3. Some trees are timber trees, while others do not bear that 
  denomination. Vide Timber, and 2 Bl. Com. 281. 
       4. Trees belong to the owner of the land where they grow, but if the 
  roots go out of one man's land into that of another, or the branches spread 
  over the adjoining estates, such roots or branches may be cut off by the 
  owner of the land into which they thus grow. Rolle's R. 394; 3 Bulst. 198; 
  Vin. Ab. Trees, E; and tit. Nuisance, W 2, pl. 3; 8 Com. Dig. 983; 2 Com. 
  Dig. 274; 10 Vin. Ab. 142; 20 Viii. Ab. 415; 22 Vin. Ab. 583; 1 Supp. to 
  Ves. jr. 138; 2 Supp. to Ves. jr. 162, 448; 6 Ves. 109. 
       5. When the roots grow into the adjoining land, the owner of such land 
  may lawfully claim a right to hold the tree in common with the owner of the 
  land where it was planted; but if the branches only overshadow the adjoining 
  land, and the root does not enter it, the tree wholly belongs owner of the 
  estate where the roots grow. 1 Swift's Dig. 104; 1 Hill. Ab. 6; 1 Ld. Raym. 
  737. Vide 13 Pick. R. 44; 1 Pick., R. 224; 4 Mass. R. 266; 6 N. H. Rep. 430;

  897; S. C. 8 D. & R. 651. When the tree grows directly on the boundary line, 
  so that the line passes through it, it is the property of both owners, 
  whether it be marked as a boundary or not. 12 N. H. Rep. 454. 
  
  

From The Devil's Dictionary (1881-1906) :

  TREE, n.  A tall vegetable intended by nature to serve as a penal
  apparatus, though through a miscarriage of justice most trees bear
  only a negligible fruit, or none at all.  When naturally fruited, the
  tree is a beneficient agency of civilization and an important factor
  in public morals.  In the stern West and the sensitive South its fruit
  (white and black respectively) though not eaten, is agreeable to the
  public taste and, though not exported, profitable to the general
  welfare.  That the legitimate relation of the tree to justice was no
  discovery of Judge Lynch (who, indeed, conceded it no primacy over the
  lamp-post and the bridge-girder) is made plain by the following
  passage from Morryster, who antedated him by two centuries:
  
          While in yt londe I was carried to see ye Ghogo tree, whereof
      I had hearde moch talk; but sayynge yt I saw naught remarkabyll in
      it, ye hed manne of ye villayge where it grewe made answer as
      followeth:
          "Ye tree is not nowe in fruite, but in his seasonne you shall
      see dependynge fr. his braunches all soch as have affroynted ye
      King his Majesty."
          And I was furder tolde yt ye worde "Ghogo" sygnifyeth in yr
      tong ye same as "rapscal" in our owne.
                                                 _Trauvells in ye Easte_
