THE  SHADDOCK,  GRAPE  FRUIT  AND  FORBIDDEN  ~ 
FRUIT. 
By  Chas.  H.  LaWau,. 
Shaddock  and  Grape  Fruit,  Citrus  decumana,  Willd.;  Forbidden 
Fruit,  Citrus  Paradisi,  Macf.;  natural  order,  Rutaceae. 
In  October,  1895,  the  author  of  the  following  communication  was 
requested  by  Prof.  Trimble  to  take  up  the  subject  of  the  grape  fruit 
or  shaddock,  and,  after  reviewing  the  literature,  to  write  a  paper 
considering  the  subject  from  its  botanical,  economical,  pharmaceut- 
ical and  chemical  standpoints.  Before  submitting  the  results  of  his 
work,  the  author  wishes  to  confess  his  inability  to  do  justice  to  the 
subject,  the  magnitude  of  which  was  fully  appreciated  shortly  after 
the  work  was  commenced.  It  is  hoped  that  this  apology  will  atone 
for  any  incompleteness  which  may  be  evident  to  those  who  are 
thoroughly  familiar  with  the  subject. 
In  considering  the  flora  of  a  given  locality,  the  customary  method 
of  procedure  is  to  arrange  the  plants  in  the  following  order  :  (1) 
Indigenous  plants;  (2)  Plants  which  have  become  perfectly  natural- 
ized ;  (3)  Plants  under  successful  cultivation.  According  to  this 
order  of  preference,  the  members  of  the  Citrus  genus  would  be  of 
tertiary  importance  in  most  sub-tropical  countries,  which  is  clearly 
incorrect,  as  the  commercial  value  of  the  fruits  of  this  family  enti- 
tles them,  in  many  instances,  to  be  considered  as  primary  features 
in  the  flora  of  any  locality. 
Although  the  genus  is  of  such  a  widespread  character  at  the 
present  time,  it  was  originally  indigenous  to  a  small  portion  of  Asia.
