Sect. II. General Catalogue of Shrubs. 

 6570. In our general catalogue qf shrubs we have included several species, which, from 

 their growing with single naked stems, and forming -a spreading head at some height from 

 the ground, are correctly denominated low trees. Amygdalus communis, and various 

 species of Crataegus, L. (now Mespilus, Sm. and \V. ), may be referred to as examples. 

 As our object is to form such arrangements as will afford most facility to the gardener 

 in adjusting his plants as to height, color of the flower, and time of inflorescence, we 

 have included all woody plants which do not exceed twenty feet in height under shrubs ; 

 and all those that exceed that height (excepting the climbers and twiners) we have al- 

 lowed to retain their places in the tables of trees. Here, as before, the most ornamental 

 species and those which continue longest in bloom are distinguished by appropriate 

 marks (s and 3).
